The Semantics of Degree Relatives

Wed, 25 Mar 2026 00:00:00 +0000

Relative clauses can range over degrees, just as they can range over individuals. But this class of degree relatives is rarely studied uniformly across the diverse constructions they help form. As a result, there have been a number of construction-specific proposals to model the semantics of degree relatives: in equatives, amount relatives, and wh -exclamatives. The goals of this article are to review a standard semantics of relativization writ large, to supplement it with standard assumptions from degree semantics, and to explain how the previously strange behavior of a variety of constructions formed from degree relatives comes out as a natural consequence of a handful of straightforward assumptions. Specifically, I argue that degree relatives are just relative clauses that range over degrees, and that these degree readings of relative clauses are available wherever we have ( a ) the appropriate morphology (e.g., a relativizer that can range over degrees), ( b ) a context of...

Manner implicatures and how to spot them

Wed, 25 Mar 2026 00:00:00 +0000

The goal of this paper is to help develop a general picture of conversational implicature (Grice, 1975) by looking beyond scalar implicature to see how the phenomenon behaves in a general sense. I focus on non-scalar Quantity implicatures and Manner implicatures. I review canonical examples of Manner implicature, as well as a more recent, productive one involving gradable adjective antonym pairs (Rett, 2015). Based on these data, I argue that Manner implicatures—and conversational implicatures generally—are distinguishable primarily by their calculability; their reinforceability; their discourse sensitivity (to the Question Under Discussion; Roberts, 1990; van Kuppevelt, 1995; Simons et al., 2011); and their embeddability (under negation, propositional attitude verbs, quantifiers, etc.). I use these data to draw conclusions about the usefulness of implicature-specific operators and about ways to compositionally represent conversational implicatures.

Book review of Yoad Winter’s Elements of formal semantics (2016)

Wed, 25 Mar 2026 00:00:00 +0000

Yoad Winter’s (2016) new textbook, “Elements of formal semantics”, is a formally sophisticated introduction to semantic theory. It treats standard beginner topics (e.g. transitivity, quantifiers, relative clauses) carefully and efficiently, using a directly compositional lambda calculus.

Evaluativity across adjective and construction types: An experimental study

Wed, 25 Mar 2026 00:00:00 +0000

An adjectival construction is evaluative if and only if it conveys that the property associated with the adjective exceeds a relevant threshold. The questions of which adjectival constructions are evaluative and why have formed the foundation for semantic theories of these constructions and of adjectives themselves (Klein 1980, von Stechow 1984), although it has been alleged that these theories are based on an incomplete picture of the phenomenon of evaluativity (Bierwisch 1989, Rett 2008a). We present the first experimental tests of the scope and nature of evaluativity across adjectival constructions and adjective types. These studies confirm that evaluativity is conditioned by adjective type (relative or absolute, Kennedy & McNally 2005) and is not restricted to the positive construction. However, they also show several new and surprising aspects of evaluativity: that it is perhaps better characterized as a gradable property than a binary one; that the ways in which...

The Semantics of Emotive Markers and Other Illocutionary Content

Wed, 25 Mar 2026 00:00:00 +0000

Abstract I identify a class of expressions called ‘emotive markers,’ exemplified by fortunately and alas, which encode not-at-issue information about the speaker’s emotive attitude towards the content of the utterances they occur in. I argue that there are important differences emotive markers and other encoders of not-at-issue content, in particular utterance modifiers like frankly or evidential adverbs like apparently. In contrast to these, emotive markers can result in Moore’s Paradox and always range over their local argument. I conclude that the contribution of emotive markers should be treated as ‘illocutionary content’, on par with the speaker’s other Discourse Commitments (Gunlogson, 2001), and I model this analysis in the dynamic sub-sentential update framework in Farkas & Bruce (2010).

Children's comprehension of syntactically encoded evidentiality

The semantics of many, much, few, and little

Wed, 25 Mar 2026 00:00:00 +0000

Abstract The words many, much, few, and little (and their cross‐linguistic counterparts) are quite unusual semantically. They have traditionally been characterized as quantifiers (like every ) or adjectives (like tall ); however, these analyses can only account for instances of these terms in which they encode information about an individual or a set of individuals, as they do when they occur prenominally (in e.g., much traffic ). Recent degree‐semantic analyses instead characterize the meaning of these words in terms of intervals or sets of degrees; this accounts for their canonical uses and uses in which they don't appear to be ranging over individuals (as in their differential use, e.g., much taller ).

Weight and final vowels in the English stress system

Thu, 18 Dec 2025 00:00:00 +0000

This paper presents both dictionary evidence and experimental evidence that the quality of a word's final vowel plays a role in assigning main stress in English. Specifically, a final [i] pushes main stress leftwards – three-syllable words ending with [i] have a strong tendency to take antepenultimate stress. This pattern is compared with the Latin Stress Rule for English, according to which words with heavy penultimate syllables should have penultimate stress. Both pressures are shown to be productive in experiments. Two analyses of the final-[i] generalisation are tested, one using the ‘cloned’ constraint N on-fin F t [i], and one using the ‘parochial’ constraint A ntepenult [i], which directly penalises [i]-final words which do not have antepenultimate stress. Although it is has less typological support, A ntepenult [i] is argued for on the grounds that it correctly predicts participants' behaviour on words with both a heavy penult and a final [i], which are extremely rare...

Learning Accurate Onset Clusters: Perception Lags Behind Production.

Thu, 18 Dec 2025 00:00:00 +0000

This study investigates young school-aged children's knowledge (at 4-7 years) of accurate English word-initial onset clusters. By this age, we expect children to be mostly accurate in producing #CC clusters (rather than repairing them with deletion or epenthesis). We ask how well can they recognize and reject cluster repair errors, in both real and nonce word tasks. The results suggest that these learners' cluster judgment skills lag behind their cluster production abilities, and that asymmetries in error types do not overall align between the two domains. Perceptual errors are made most often when comparing clusters with epenthesis repairs, not deletion, and the cluster's sonority profile does not directly influence error rates. After comparing these findings with similar results from adult L2 English speakers as well, we discuss the ways in which issues like recoverability, salience, and contiguity can account for our findings. We also suggest that more work on phonological...

Violations of Lab-Learned Phonological Patterns Elicit a Late Positive Component

Thu, 18 Dec 2025 00:00:00 +0000

The experimental study of artificial language learning has become a widely used means of investigating the predictions of theories of language learning and representation. Although much is now known about the generalizations that learners make from various kinds of data, relatively little is known about how those representations affect speech processing. This paper presents an event-related potential (ERP) study of brain responses to violations of lab-learned phonotactics. Novel words that violated a learned phonotactic constraint elicited a larger Late Positive Component (LPC) than novel words that satisfied it. Similar LPCs have been found for violations of natively acquired linguistic structure, as well as for violations of other types of abstract generalizations, such as musical structure. We argue that lab-learned phonotactic generalizations are represented abstractly and affect the evaluation of speech in a manner that is similar to natively acquired syntactic and phonological...

San Martín Peras Mixtec

Thu, 11 Dec 2025 00:00:00 +0000

San Martín Peras Mixtec (autonym: Tu’un Nta’vi or Tu’un Savi) is an Otomanguean language spoken by roughly 11,500 people in the municipality of San Martín Peras, in Oaxaca, Mexico (Instituto Nacional de Estadística y Geografía, 2020), as shown in Figure 1. The municipality is in the district of Juxtlahuaca, bordering the state of Guerrero. As of 2020, approximately 97% of the population of the municipality over three years old is a speaker of an Indigenous language. Of those that speak an Indigenous language, approximately 60% also speak Spanish, meaning that around 37% of the total population is monolingual in Mixtec (Instituto Nacional de Estadística y Geografía, 2020). Despite these figures, it is difficult to estimate the total number of native speakers of the language, as many community members have migrated to other parts of Mexico and the United States, especially to several towns in California (Mendoza, 2020).

Laryngeal reduction and mora deletion in Mixtec

Thu, 11 Dec 2025 00:00:00 +0000

This paper describes a process of laryngeal reduction in San Mart´ın Peras Mixtec (SMPM; ISO: jmx), an Otomanguean language spoken in Oaxaca and by diasporic communities throughout Mexico and the US. In this process, roots containing a laryngealized vowel often appear in a highly reduced form in fast speech. Laryngeal reduction is gradient, dependent on speech rate, and lacks a phonologically-defined conditioning environment, giving it the characteristics of a phonetic process. However, it is at least sometimes correlated with a phonological process of mora deletion, as evidenced by the fact that some highly reduced laryngealized roots—but no unreduced laryngealized roots—undergo a phonolog-ical tone sandhi alternation that applies only to mono-moraic rising tones. The phonological process of mora deletion is argued to be conditioned by the same phonetic factors that drive laryngeal reduction, constituting an instance of a phonological process triggered by purportedly phonetic factors.

English-Learning Infants’ Developing Sensitivity to Intonation Contours

Wed, 27 Aug 2025 00:00:00 +0000

In four experiments, we investigated when and how English-learning infants perceive intonation contours that signal prosodic units. Using visual habituation, we probed infants’ ability to discriminate disyllabic sequences with a fall versus a rise in pitch on the final syllable, a salient cue used to distinguish statements from questions. First, we showed that at 8 months, English-learning infants can distinguish statement falls from question rises, as has been reported previously for their European Portuguese-learning peers who have extensive experience with minimal pairs that differ just in pitch rises and falls. Next, we conducted three experiments involving 4-month-olds to determine the developmental roots of how English-learning infants begin to tune into these intonation contours. In Experiment 2, we showed that unlike 8-month-olds, monolingual English-learning 4-month-olds are unable to distinguish statement and question intonation when they are presented with segmentally...

Infants discover English suffixes allomorph by allomorph.

Wed, 27 Aug 2025 00:00:00 +0000

Recent research has shown that 6-month-olds relate novel words suffixed with -s, like babs, that are embedded in passages, with just the stem bab, demonstrating an early sensitivity to morphological relatedness. This study builds on these findings by investigating the role of allomorphy in early morphological acquisition. We tested whether infants relate novel words suffixed with [-z] and [-s] allomorphs of the -s suffix and their stems. We find that English-learning 6-month-olds relate novel words suffixed with the [-z], but not [-s], allomorph with stems, providing evidence for an acquisition trajectory where infants discover morphemes one allomorph at a time.

The UCI Phonotactic Calculator: An online tool for computing phonotactic metrics

Wed, 16 Jul 2025 00:00:00 +0000

This paper presents the UCI Phonotactic Calculator (UCIPC), a new online tool for quantifying the occurrence of segments and segment sequences in a corpus. This tool has several advantages compared to existing tools: it allows users to supply their own training data, meaning it can be applied to any language for which a corpus is available; it computes a wider range of metrics than most existing tools; and it provides an accessible point-and-click interface that allows researchers with more modest technical backgrounds to take advantage of phonotactic models. After describing the metrics implemented by the calculator and how to use it, we present the results of a proof-of-concept study comparing how well different types of metrics implemented by the UCIPC predict human responses from eight published nonce word acceptability judgment studies across four different languages. These results suggest that metrics that take into account the relative position of sounds and include word...

An outline of the narrative grammar of electronic dance music

Wed, 21 May 2025 00:00:00 +0000

We argue that electronic dance music (EDM) exhibits a parallel structural organization to that which has been proposed for cartoons (comics) after the model of hierarchical structure proposed in theoretical linguistics. According to this parallel, both systems are governed by general cognitive mechanisms for the narrative organization of tension and release, which are not modality-specific. We show that notions from visual narrative analysis, such as an Establisher–Initial–Peak–Release template, can be applied directly to EDM tracks as an Intro/Breakdown–Buildup–Core–Outro/Cut template. In doing so, we focus on how to formally define and operationalize relevant notions such as Breakdown, Buildup, and Core. As part of our analysis, we show that the scene-setting Establisher segments of visual narratives map onto two distinct categories in EDM: they correspond to intro sections at the beginning of a track and to breakdown sections in the middle of a track; we strengthen the analogy...

Is Second Language Attrition Inevitable After Instruction Ends? An Exploratory Longitudinal Study of Advanced Instructed Second Language Users

Wed, 14 May 2025 00:00:00 +0000

Abstract: Most second language acquisition (SLA) research has documented the processes involved in learning second/foreign languages, with few studies focusing on the durability of attained second language (L2) skills once instructed learners/users are no longer receiving formal instruction. The current study examines the effects of continued exposure and peak instructional attainment on the long‐term evolution of advanced, instructed L2 learners’ skills following a longitudinal mixed‐methods research design. Participants (n = 28) completed an oral proficiency test, an oral interview, and a vocabulary knowledge test at multiple times over an 8‐year period, 6 years of which were postinstruction. Results showed that continued exposure contributes to long‐term retention (and some further development) of oral proficiency and fluency and that peak attainment at the end of formal instruction is also an important variable for some areas of L2 performance. Additionally, even the participants...

Functional characterization of the language network of polyglots and hyperpolyglots with precision fMRI

Thu, 20 Mar 2025 00:00:00 +0000

How do polyglots-individuals who speak five or more languages-process their languages, and what can this population tell us about the language system? Using fMRI, we identified the language network in each of 34 polyglots (including 16 hyperpolyglots with knowledge of 10+ languages) and examined its response to the native language, non-native languages of varying proficiency, and unfamiliar languages. All language conditions engaged all areas of the language network relative to a control condition. Languages that participants rated as higher proficiency elicited stronger responses, except for the native language, which elicited a similar or lower response than a non-native language of similar proficiency. Furthermore, unfamiliar languages that were typologically related to the participants' high-to-moderate-proficiency languages elicited a stronger response than unfamiliar unrelated languages. The results suggest that the language network's response magnitude scales with the degree...

Watching videos of a drawing hand improves students’ understanding of the normal probability distribution

Mon, 17 Feb 2025 00:00:00 +0000

Understanding normal probability distributions is a crucial objective in mathematics and statistics education. Drawing upon cognitive psychology research, this study explores the use of drawings and visualizations as effective scaffolds to enhance students' comprehension. Although much research has documented the helpfulness of drawing as a research tool to reveal students’ knowledge states, its direct utility in advancing higher-order cognitive processes remains understudied. In Study 1, qualitative methods were utilized to identify common misunderstandings among students regarding canonical depictions of the normal probability distribution. Building on these insights, Study 2 experimentally compared three instructional videos (static slides, dynamic drawing, and dynamic drawings done by a visible hand). The hand drawing video led to better learning than the other versions. Study 3 examined whether the benefits from observing a hand drawing could be reproduced by a dynamic cursor...

Semantic projection recovers rich human knowledge of multiple object features from word embeddings

Fri, 31 Jan 2025 00:00:00 +0000

How is knowledge about word meaning represented in the mental lexicon? Current computational models infer word meanings from lexical co-occurrence patterns. They learn to represent words as vectors in a multidimensional space, wherein words that are used in more similar linguistic contexts—that is, are more semantically related—are located closer together. However, whereas inter-word proximity captures only overall relatedness, human judgements are highly context dependent. For example, dolphins and alligators are similar in size but differ in dangerousness. Here, we use a domain-general method to extract context-dependent relationships from word embeddings: ‘semantic projection’ of word-vectors onto lines that represent features such as size (the line connecting the words ‘small’ and ‘big’) or danger (‘safe’ to ‘dangerous’), analogous to ‘mental scales’. This method recovers human judgements across various object categories and properties. Thus, the geometry of word embeddings...

The Natural Stories corpus: a reading-time corpus of English texts containing rare syntactic constructions.

Thu, 21 Nov 2024 00:00:00 +0000

It is now a common practice to compare models of human language processing by comparing how well they predict behavioral and neural measures of processing difficulty, such as reading times, on corpora of rich naturalistic linguistic materials. However, many of these corpora, which are based on naturally-occurring text, do not contain many of the low-frequency syntactic constructions that are often required to distinguish between processing theories. Here we describe a new corpus consisting of English texts edited to contain many low-frequency syntactic constructions while still sounding fluent to native speakers. The corpus is annotated with hand-corrected Penn Treebank-style parse trees and includes self-paced reading time data and aligned audio recordings. We give an overview of the content of the corpus, review recent work using the corpus, and release the data.

Broca’s Area Is Not a Natural Kind

Thu, 21 Nov 2024 00:00:00 +0000

Theories of human cognition prominently feature 'Broca's area', which causally contributes to a myriad of mental functions. However, Broca's area is not a monolithic, multipurpose unit - it is structurally and functionally heterogeneous. Some functions engaging (subsets of) this area share neurocognitive resources, whereas others rely on separable circuits. A decade of converging evidence has now illuminated a fundamental distinction between two subregions of Broca's area that likely play computationally distinct roles in cognition: one belongs to the domain-specific 'language network', the other to the domain-general 'multiple-demand (MD) network'. Claims about Broca's area should be (re)cast in terms of these (and other, as yet undetermined) functional components, to establish a cumulative research enterprise where empirical findings can be replicated and theoretical proposals can be meaningfully compared and falsified.

The Small and Efficient Language Network of Polyglots and Hyper-polyglots

Thu, 21 Nov 2024 00:00:00 +0000

Acquiring a foreign language is challenging for many adults. Yet certain individuals choose to acquire sometimes dozens of languages and often just for fun. Is there something special about the minds and brains of such polyglots? Using robust individual-level markers of language activity, measured with fMRI, we compared native language processing in polyglots versus matched controls. Polyglots (n = 17, including nine "hyper-polyglots" with proficiency in 10-55 languages) used fewer neural resources to process language: Their activations were smaller in both magnitude and extent. This difference was spatially and functionally selective: The groups were similar in their activation of two other brain networks-the multiple demand network and the default mode network. We hypothesize that the activation reduction in the language network is experientially driven, such that the acquisition and use of multiple languages makes language processing generally more efficient. However, genetic...

The Domain-General Multiple Demand (MD) Network Does Not Support Core Aspects of Language Comprehension: A Large-Scale fMRI Investigation

Thu, 21 Nov 2024 00:00:00 +0000

Aside from the language-selective left-lateralized frontotemporal network, language comprehension sometimes recruits a domain-general bilateral frontoparietal network implicated in executive functions: the multiple demand (MD) network. However, the nature of the MD network's contributions to language comprehension remains debated. To illuminate the role of this network in language processing in humans, we conducted a large-scale fMRI investigation using data from 30 diverse word and sentence comprehension experiments (481 unique participants [female and male], 678 scanning sessions). In line with prior findings, the MD network was active during many language tasks. Moreover, similar to the language-selective network, which is robustly lateralized to the left hemisphere, these responses were stronger in the left-hemisphere MD regions. However, in contrast with the language-selective network, the MD network responded more strongly (1) to lists of unconnected words than to sentences,...

Differential Tracking of Linguistic vs. Mental State Content in Naturalistic Stimuli by Language and Theory of Mind (ToM) Brain Networks

Thu, 21 Nov 2024 00:00:00 +0000

Language and social cognition, especially the ability to reason about mental states, known as theory of mind (ToM), are deeply related in development and everyday use. However, whether these cognitive faculties rely on distinct, overlapping, or the same mechanisms remains debated. Some evidence suggests that, by adulthood, language and ToM draw on largely distinct-though plausibly interacting-cortical networks. However, the broad topography of these networks is similar, and some have emphasized the importance of social content / communicative intent in the linguistic signal for eliciting responses in the language areas. Here, we combine the power of individual-subject functional localization with the naturalistic-cognition inter-subject correlation approach to illuminate the language-ToM relationship. Using functional magnetic resonance imaging (fMRI), we recorded neural activity as participants (n = 43) listened to stories and dialogues with mental state content...

Non-literal language processing is jointly supported by the language and theory of mind networks: Evidence from a novel meta-analytic fMRI approach

Thu, 21 Nov 2024 00:00:00 +0000

Going beyond the literal meaning of language is key to communicative success. However, the mechanisms that support non-literal inferences remain debated. Using a novel meta-analytic approach, we evaluate the contribution of linguistic, social-cognitive, and executive mechanisms to non-literal interpretation. We identified 74 fMRI experiments (n = 1,430 participants) from 2001 to 2021 that contrasted non-literal language comprehension with a literal control condition, spanning ten phenomena (e.g., metaphor, irony, indirect speech). Applying the activation likelihood estimation approach to the 825 activation peaks yielded six left-lateralized clusters. We then evaluated the locations of both the individual-study peaks and the clusters against probabilistic functional atlases (cf. anatomical locations, as is typically done) for three candidate brain networks-the language-selective network (Fedorenko, Behr, & Kanwisher, 2011), which supports language processing, the...

Lack of selectivity for syntax relative to word meanings throughout the language network

Thu, 21 Nov 2024 00:00:00 +0000

To understand what you are reading now, your mind retrieves the meanings of words and constructions from a linguistic knowledge store (lexico-semantic processing) and identifies the relationships among them to construct a complex meaning (syntactic or combinatorial processing). Do these two sets of processes rely on distinct, specialized mechanisms or, rather, share a common pool of resources? Linguistic theorizing, empirical evidence from language acquisition and processing, and computational modeling have jointly painted a picture whereby lexico-semantic and syntactic processing are deeply inter-connected and perhaps not separable. In contrast, many current proposals of the neural architecture of language continue to endorse a view whereby certain brain regions selectively support syntactic/combinatorial processing, although the locus of such "syntactic hub", and its nature, vary across proposals. Here, we searched for selectivity for syntactic over lexico-semantic processing...

Activity in the fronto-parietal multiple-demand network is robustly associated with individual differences in working memory and fluid intelligence.

Thu, 21 Nov 2024 00:00:00 +0000

Numerous brain lesion and fMRI studies have linked individual differences in executive abilities and fluid intelligence to brain regions of the fronto-parietal multiple-demand (MD) network. Yet, fMRI studies have yielded conflicting evidence as to whether better executive abilities are associated with stronger or weaker MD activations and whether this relationship is restricted to the MD network. Here, in a large-sample (n = 216) fMRI investigation, we found that stronger activity in MD regions - functionally defined in individual participants - was robustly associated with more accurate and faster responses on a spatial working memory task performed in the scanner, as well as fluid intelligence measured independently (n = 114). In line with some prior claims about a relationship between language and fluid intelligence, we also found a weak association between activity in the brain regions of the left fronto-temporal language network during an independent passive...

The Language Network Reliably “Tracks” Naturalistic Meaningful Nonverbal Stimuli

Wed, 20 Nov 2024 00:00:00 +0000

The language network, comprised of brain regions in the left frontal and temporal cortex, responds robustly and reliably during language comprehension but shows little or no response during many nonlinguistic cognitive tasks (e.g., Fedorenko & Blank, 2020). However, one domain whose relationship with language remains debated is semantics-our conceptual knowledge of the world. Given that the language network responds strongly to meaningful linguistic stimuli, could some of this response be driven by the presence of rich conceptual representations encoded in linguistic inputs? In this study, we used a naturalistic cognition paradigm to test whether the cognitive and neural resources that are responsible for language processing are also recruited for processing semantically rich nonverbal stimuli. To do so, we measured BOLD responses to a set of ∼5-minute-long video and audio clips that consisted of meaningful event sequences but did not contain any linguistic content. We then...

The neural architecture of language: Integrative modeling converges on predictive processing

Wed, 20 Nov 2024 00:00:00 +0000

The neuroscience of perception has recently been revolutionized with an integrative modeling approach in which computation, brain function, and behavior are linked across many datasets and many computational models. By revealing trends across models, this approach yields novel insights into cognitive and neural mechanisms in the target domain. We here present a systematic study taking this approach to higher-level cognition: human language processing, our species' signature cognitive skill. We find that the most powerful "transformer" models predict nearly 100% of explainable variance in neural responses to sentences and generalize across different datasets and imaging modalities (functional MRI and electrocorticography). Models' neural fits ("brain score") and fits to behavioral responses are both strongly correlated with model accuracy on the next-word prediction task (but not other language tasks). Model architecture appears to substantially contribute to neural fit. These...

Probabilistic atlas for the language network based on precision fMRI data from >800 individuals

Wed, 20 Nov 2024 00:00:00 +0000

Two analytic traditions characterize fMRI language research. One relies on averaging activations across individuals. This approach has limitations: because of inter-individual variability in the locations of language areas, any given voxel/vertex in a common brain space is part of the language network in some individuals but in others, may belong to a distinct network. An alternative approach relies on identifying language areas in each individual using a functional ‘localizer’. Because of its greater sensitivity, functional resolution, and interpretability, functional localization is gaining popularity, but it is not always feasible, and cannot be applied retroactively to past studies. To bridge these disjoint approaches, we created a probabilistic functional atlas using fMRI data for an extensively validated language localizer in 806 individuals. This atlas enables estimating the probability that any given location in a common space belongs to the language network, and thus...

Robust Effects of Working Memory Demand during Naturalistic Language Comprehension in Language-Selective Cortex

Wed, 20 Nov 2024 00:00:00 +0000

To understand language, we must infer structured meanings from real-time auditory or visual signals. Researchers have long focused on word-by-word structure building in working memory as a mechanism that might enable this feat. However, some have argued that language processing does not typically involve rich word-by-word structure building, and/or that apparent working memory effects are underlyingly driven by surprisal (how predictable a word is in context). Consistent with this alternative, some recent behavioral studies of naturalistic language processing that control for surprisal have not shown clear working memory effects. In this fMRI study, we investigate a range of theory-driven predictors of word-by-word working memory demand during naturalistic language comprehension in humans of both sexes under rigorous surprisal controls. In addition, we address a related debate about whether the working memory mechanisms involved in language comprehension are language specialized...

Incremental Language Comprehension Difficulty Predicts Activity in the Language Network but Not the Multiple Demand Network

Wed, 20 Nov 2024 00:00:00 +0000

What role do domain-general executive functions play in human language comprehension? To address this question, we examine the relationship between behavioral measures of comprehension and neural activity in the domain-general "multiple demand" (MD) network, which has been linked to constructs like attention, working memory, inhibitory control, and selection, and implicated in diverse goal-directed behaviors. Specifically, functional magnetic resonance imaging data collected during naturalistic story listening are compared with theory-neutral measures of online comprehension difficulty and incremental processing load (reading times and eye-fixation durations). Critically, to ensure that variance in these measures is driven by features of the linguistic stimulus rather than reflecting participant- or trial-level variability, the neuroimaging and behavioral datasets were collected in nonoverlapping samples. We find no behavioral-neural link in functionally localized MD regions;...

The language network ages well: Preserved selectivity, lateralization, and within-network functional synchronization in older brains

Tue, 19 Nov 2024 00:00:00 +0000

Healthy aging is associated with structural and functional brain changes. However, cognitive abilities differ from one another in how they change with age: whereas executive functions, like working memory, show age-related decline, aspects of linguistic processing remain relatively preserved (Hartshorne et al., 2015). This heterogeneity of the cognitive-behavioral landscape in aging predicts differences among brain networks in whether and how they should change with age. To evaluate this prediction, we used individual-subject fMRI analyses ('precision fMRI') to examine the language-selective network (Fedorenko et al., 2024) and the Multiple Demand (MD) network, which supports executive functions (Duncan et al., 2020), in older adults (n=77) relative to young controls (n=470). In line with past claims, relative to young adults, the MD network of older adults shows weaker and less spatially extensive activations during an executive function task and reduced within-network functional...

More on (the Lack of) Reconstruction in English Tough-Constructions

Abstract: This squib presents three new arguments that the matrix subject in English tough-constructions cannot reconstruct into the embedded gap. The first two arguments reexamine data in the literature purported to show such reconstruction. Upon closer scrutiny, we argue that these data in fact involve short reconstruction below a modal or generic operator in the matrix clause, and not genuine long reconstruction into the embedded gap. The third argument is that property positions, which independently require reconstruction, are unable to host tough-gaps. This ban on long reconstruction in English tough-constructions follows without further ado on a base-generation analysis.

Improper case

Thu, 20 Jun 2024 00:00:00 +0000

Abstract: This paper argues that case assignment is impossible in configurations that parallel generalized improper-movement configurations. Thus, like improper movement, there is “improper case.” The empirical motivation comes from (i) the interaction between case and movement and (ii) crossclausal case assignment in Finnish. I propose that improper case is ruled out by theBan on Improper Case: a DP in [Spec, XP] cannot establish a dependent-case relationship with a lower DP across YP if Y is higher than X in the functional sequence. I show that this constraint falls under a strong version of theWilliams Cycle(Williams 1974, 2003, 2013; van Riemsdijk and Williams 1981) and is derived under Williams’s (2003, 2013) analysis of embedding.

Dependent-case assignment could be AGREE

Thu, 20 Jun 2024 00:00:00 +0000

Preminger (to appear) claims that an AGREE-based theory of case assignment undergenerates because it cannot handle attested dependent-case patterns. This paper argues that dependent-case assignment can in fact be modelled using the operation AGREE, building on independently motivated assumptions. Therefore, an AGREE-based theory of case assignment does not undergenerate.

Not all reconstruction effects are syntactic

Thu, 20 Jun 2024 00:00:00 +0000

Abstract: This paper argues that not all reconstruction effects can be reduced to a syntactic mechanism that selectively interprets copies at LF. The argument is based on the novel observation that some but not all reconstruction effects induce Condition C connectivity in Hindi-Urdu. We contend that Hindi-Urdu requires the hybrid approach to reconstruction developed on independent grounds by Lechner (1998, 2013, 2019), where both copy neglect (a syntactic mechanism) and higher-type traces (a semantic mechanism) are available as independent interpretive mechanisms. We show that the interaction of these two modes of reconstruction derives the intricate reconstruction facts in Hindi-Urdu.

How to vocode: Using channel vocoders for cochlear-implant research

Thu, 11 Apr 2024 00:00:00 +0000

The channel vocoder has become a useful tool to understand the impact of specific forms of auditory degradation-particularly the spectral and temporal degradation that reflect cochlear-implant processing. Vocoders have many parameters that allow researchers to answer questions about cochlear-implant processing in ways that overcome some logistical complications of controlling for factors in individual cochlear implant users. However, there is such a large variety in the implementation of vocoders that the term "vocoder" is not specific enough to describe the signal processing used in these experiments. Misunderstanding vocoder parameters can result in experimental confounds or unexpected stimulus distortions. This paper highlights the signal processing parameters that should be specified when describing vocoder construction. The paper also provides guidance on how to determine vocoder parameters within perception experiments, given the experimenter's goals and research questions,...

A meta-analytic review of morphological priming in Semitic languages

Wed, 27 Mar 2024 00:00:00 +0000

Two types of discontinuous morphemes are thought to be the basic building blocks of words in Semitic languages: roots and templates. However, the role of these morphemes in lexical access and representation is debated. Priming experiments, where reaction times to target words are predicted to be faster when preceded by morphologically-related primes compared to unrelated control primes, provide conflicting evidence bearing on this debate. We used meta-analysis to synthesise the findings from 229 priming experiments on 4710 unique Semitic speakers. With Bayesian modelling of the aggregate effect sizes, we found credible root and template priming in both nouns and verbs in Arabic and Hebrew. Our results show that root priming effects can be distinguished from the effects of overlap in form and meaning. However, more experiments are needed to determine if template priming effects can be distinguished from overlap in form and morphosyntactic function.

The everyday speech environments of preschoolers with and without cochlear implants.

Wed, 27 Mar 2024 00:00:00 +0000

Children who receive cochlear implants develop spoken language on a protracted timescale. The home environment facilitates speech-language development, yet it is relatively unknown how the environment differs between children with cochlear implants and typical hearing. We matched eighteen preschoolers with implants (31-65 months) to two groups of children with typical hearing: by chronological age and hearing age. Each child completed a long-form, naturalistic audio recording of their home environment (appx. 16 hours/child; >730 hours of observation) to measure adult speech input, child vocal productivity, and caregiver-child interaction. Results showed that children with cochlear implants and typical hearing were exposed to and engaged in similar amounts of spoken language with caregivers. However, the home environment did not reflect developmental stages as closely for children with implants, or predict their speech outcomes as strongly. Home-based speech-language interventions...

6–month–olds are sensitive to English morphology

Wed, 27 Mar 2024 00:00:00 +0000

Each language has its unique way to mark grammatical information such as gender, number and tense. For example, English marks number and tense/aspect information with morphological suffixes (e.g., -s or -ed). These morphological suffixes are crucial for language acquisition as they are the basic building blocks of syntax, encode relationships, and convey meaning. Previous research shows that English-learning infants recognize morphological suffixes attached to nonce words by the end of the first year, although even 8-month-olds recognize them when they are attached to known words. These results support an acquisition trajectory where discovery of meaning guides infants' acquisition of morphological suffixes. In this paper, we re-evaluated English-learning infants' knowledge of morphological suffixes in the first year of life. We found that 6-month-olds successfully segmented nonce words suffixed with -s, -ing, -ed and a pseudo-morpheme -sh. Additionally, they related nonce words...

Disentangling the Role of Biphone Probability From Neighborhood Density in the Perception of Nonwords

Wed, 27 Mar 2024 00:00:00 +0000

In six experiments we explored how biphone probability and lexical neighborhood density influence listeners' categorization of vowels embedded in nonword sequences. We found independent effects of each. Listeners shifted categorization of a phonetic continuum to create a higher probability sequence, even when neighborhood density was controlled. Similarly, listeners shifted categorization to create a nonword from a denser neighborhood, even when biphone probability was controlled. Next, using a visual world eye-tracking task, we determined that biphone probability information is used rapidly by listeners in perception. In contrast, task complexity and irrelevant variability in the stimuli interfere with neighborhood density effects. These results support a model in which both biphone probability and neighborhood density independently affect word recognition, but only biphone probability effects are observed early in processing.

Constraints on Acceleration in Bilingual Development: Evidence from Word Segmentation by Spanish Learning Infants

Wed, 27 Mar 2024 00:00:00 +0000

We have previously shown that bilingual Spanish and English-learning infants can segment English iambs, two-syllable words with final stress (e.g., guiTAR), earlier than their monolingual peers. This is consistent with accelerated development in bilinguals and was attributed to bilingual infants' increased exposure to iambs through Spanish; about 10% of English content words start with an unstressed syllable, compared to 40% in Spanish. Here, we evaluated whether increased exposure to a stress pattern alone is sufficient to account for acceleration in bilingual infants. In English, 90% of content words start with a stressed syllable (e.g., KINGdom), compared to 60% in Spanish. However, we found no evidence for accelerated segmentation of Spanish trochees by Spanish-English bilingual infants compared to their monolingual Spanish-learning peers. Based on this finding, we argue that merely increased exposure to a linguistic feature in one language does not result in accelerated development...

A Multilab Study of Bilingual Infants: Exploring the Preference for Infant-Directed Speech

Wed, 27 Mar 2024 00:00:00 +0000

From the earliest months of life, infants prefer listening to and learn better from infant-directed speech (IDS) than adult-directed speech (ADS). Yet, IDS differs within communities, across languages, and across cultures, both in form and in prevalence. This large-scale, multi-site study used the diversity of bilingual infant experiences to explore the impact of different types of linguistic experience on infants' IDS preference. As part of the multi-lab ManyBabies 1 project, we compared lab-matched samples of 333 bilingual and 385 monolingual infants' preference for North-American English IDS (cf. ManyBabies Consortium, 2020: ManyBabies 1), tested in 17 labs in 7 countries. Those infants were tested in two age groups: 6-9 months (the younger sample) and 12-15 months (the older sample). We found that bilingual and monolingual infants both preferred IDS to ADS, and did not differ in terms of the overall magnitude of this preference. However, amongst bilingual infants who were...

Spectral and temporal measures of coarticulation in child speech

Sun, 25 Feb 2024 00:00:00 +0000

Speech produced by children is characterized by a high fundamental frequency which complicates measurement of vocal tract resonances, and hence coarticulation. Here two whole-spectrum measures of coarticulation are validated, one temporal and one spectral, that are less sensitive to these challenges. Using these measures, consonant-vowel coarticulation is calculated in the speech of a large sample of 4-year-old children. The measurements replicate known lingual coarticulatory findings from the literature, demonstrating the utility of these acoustic measures of coarticulation in speakers of all ages.

Information conveyed by voice qualitya)

Wed, 21 Feb 2024 00:00:00 +0000

The problem of characterizing voice quality has long caused debate and frustration. The richness of the available descriptive vocabulary is overwhelming, but the density and complexity of the information voices convey lead some to conclude that language can never adequately specify what we hear. Others argue that terminology lacks an empirical basis, so that language-based scales are inadequate a priori. Efforts to provide meaningful instrumental characterizations have also had limited success. Such measures may capture sound patterns but cannot at present explain what characteristics, intentions, or identity listeners attribute to the speaker based on those patterns. However, some terms continually reappear across studies. These terms align with acoustic dimensions accounting for variance across speakers and languages and correlate with size and arousal across species. This suggests that labels for quality rest on a bedrock of biology: We have evolved to perceive voices in terms...

Neurophysiological dynamics of phrase-structure building during sentence processing

Sat, 9 Sep 2023 00:00:00 +0000

Although sentences unfold sequentially, one word at a time, most linguistic theories propose that their underlying syntactic structure involves a tree of nested phrases rather than a linear sequence of words. Whether and how the brain builds such structures, however, remains largely unknown. Here, we used human intracranial recordings and visual word-by-word presentation of sentences and word lists to investigate how left-hemispheric brain activity varies during the formation of phrase structures. In a broad set of language-related areas, comprising multiple superior temporal and inferior frontal sites, high-gamma power increased with each successive word in a sentence but decreased suddenly whenever words could be merged into a phrase. Regression analyses showed that each additional word or multiword phrase contributed a similar amount of additional brain activity, providing evidence for a merge operation that applies equally to linguistic objects of arbitrary complexity. More...

On Peer Review

Tue, 4 Jul 2023 00:00:00 +0000

PURPOSE: This letter briefly reviews ideas about the purpose and benefits of peer review and reaches some idealistic conclusions about the process. METHOD: The author uses both literature review and meditation born of long experience. RESULTS: From a cynical perspective, peer review constitutes an adversarial process featuring domination of the weak by the strong and exploitation of authors and reviewers by editors and publishers, resulting in suppression of new ideas, delayed publication of important research, and bad feelings ranging from confusion to fury. More optimistically, peer review can be viewed as a system in which reviewers and editors volunteer thousands of hours to work together with authors, to the end of furthering human knowledge. CONCLUSION: Editors and authors will encounter both peer-review cynics and idealists in their careers, but in the author's experience the second are far more prevalent. Reviewers and editors can help increase the positive benefits of...

Perceptual consequences of changes in epilaryngeal area and shape

Tue, 4 Jul 2023 00:00:00 +0000

The influence of epilaryngeal area on glottal flow and the acoustic signal has been described [Titze, J. Acoust. Soc. Am. 123, 2733-2749 (2008)], but it is not known how (or whether) changes in epilaryngeal area influence perceived voice quality. This study examined these relationships in a kinematic vocal tract model. Epilaryngeal constrictions and expansions were simulated at the levels of the aryepiglottic folds and the ventricular folds in the context of four glottal configurations representing normal vibration to severe vocal fold paralysis, for the three corner vowels /a/, /i/, and /u/. Minimum and maximum glottal flow, maximum flow declination rate, spectral slope, cepstral peak prominence, and the harmonics-to-noise ratio were measured, and listeners completed a perceptual sort-and-rate task for all samples. Epilaryngeal constriction and expansion caused salient differences in voice quality. The location of constriction was also perceivable. Vowels simulated with aryepiglottic...

Towards understanding speaker discrimination abilities in humans and machines for text-independent short utterances of different speech styles

Thu, 29 Jun 2023 00:00:00 +0000

Little is known about human and machine speaker discrimination ability when utterances are very short and the speaking style is variable. This study compares text-independent speaker discrimination ability of humans and machines based on utterances shorter than 2 s in two different speaking styles (read sentences and speech directed towards pets, characterized by exaggerated prosody). Recordings of 50 female speakers drawn from the UCLA Speaker Variability Database were used as stimuli. Performance of 65 human listeners was compared to i-vector-based automatic speaker verification systems using mel-frequency cepstral coefficients, voice quality features, which were inspired by a psychoacoustic model of voice perception, or their combination by score-level fusion. Humans always outperformed machines, except in the case of style-mismatched pairs from perceptually-marked speakers. Speaker representations by humans and machines were compared using multi-dimensional scaling (MDS)....

Effects of Laryngeal Vibratory Asymmetry and Neuromuscular Compensation on Voice Quality

Thu, 22 Jun 2023 00:00:00 +0000

INTRODUCTION: Vibratory asymmetry and neuromuscular compensation are often seen in laryngeal neuromuscular pathology. However, the ramifications of these findings on voice quality are unclear. This study investigated the effects of varying levels of vibratory asymmetry and neuromuscular compensation on cepstral peak prominence (CPP), an analog of voice quality. STUDY DESIGN: In vivo canine phonation model. METHODS: Varying degrees of vocal fold vibratory asymmetry were achieved by stimulating one recurrent laryngeal nerve (RLN) over 11 levels from threshold to maximal muscle activation. For each of these levels, phonation was induced at systematically varied combinations of neuromuscular compensation: three levels each of contralateral RLN stimulation (80%, 90%, and 100% of maximal), superior laryngeal nerve (SLN) activation (0%, 50%, and 100% of maximal), and airflow levels (500, 700, and 900 mL/s). Vocal fold symmetry was determined by assessing the opening phase of the vibratory...

Perceptual Evaluation of Vocal Fold Vibratory Asymmetry

Wed, 21 Jun 2023 00:00:00 +0000

OBJECTIVES: Laryngeal vibratory asymmetry occurring with paresis may result in a perceptually normal or abnormal voice. The present study aims to determine the relationships between the degree of vibratory asymmetry, acoustic measures, and perception of sound stimuli. STUDY DESIGN: Animal Model of Voice Production, Perceptual Analysis of Voice. METHODS: In an in vivo canine model of phonation, symmetric and asymmetric laryngeal vibration were obtained via graded unilateral recurrent laryngeal nerve (RLN) stimulation simulating near paralysis to full activation. Phonation was performed at various contralateral RLN and bilateral superior laryngeal nerve stimulation levels. Naïve listeners rated the perceptual quality of 182 unique phonatory samples using a visual sort-and-rate task. Cepstral peak prominence (CPP) was calculated for each phonatory condition. The relationships among vibratory symmetry, CPP, and perceptual ratings were evaluated. RESULTS: A significant relationship...

Validating a psychoacoustic model of voice quality

Fri, 16 Jun 2023 00:00:00 +0000

No agreed-upon method currently exists for objective measurement of perceived voice quality. This paper describes validation of a psychoacoustic model designed to fill this gap. This model includes parameters to characterize the harmonic and inharmonic voice sources, vocal tract transfer function, fundamental frequency, and amplitude of the voice, which together serve to completely quantify the integral sound of a target voice sample. In experiment 1, 200 voices with and without diagnosed vocal pathology were fit with the model using analysis-by-synthesis. The resulting synthetic voice samples were not distinguishable from the original voice tokens, suggesting that the model has all the parameters it needs to fully quantify voice quality. In experiment 2 parameters that model the harmonic voice source were removed one by one, and the voice tokens were re-synthesized with the reduced model. In every case the lower-dimensional models provided worse perceptual matches to the quality...

Exposure to a second language in infancy alters speech production

Thu, 15 Jun 2023 00:00:00 +0000

We evaluated the impact of exposure to a second language on infants' emerging speech production skills. We compared speech produced by three groups of 12-month-old infants while they interacted with interlocutors who spoke to them in Spanish and English: monolingual English-learning infants who had previously received 5 hours of exposure to a second language (Spanish), English- and Spanish-learning simultaneous bilinguals, and monolingual English-learning infants without any exposure to Spanish. Our results showed that the monolingual English-learning infants with short-term exposure to Spanish and the bilingual infants, but not the monolingual English-learning infants without exposure to Spanish, flexibly matched the prosody of their babbling to that of a Spanish- or English-speaking interlocutor. Our findings demonstrate the nature and extent of benefits for language learning from early exposure to two languages. We discuss the implications of these findings for language organization...

No evidence for differences among language regions in their temporal receptive windows

Mon, 12 Jun 2023 00:00:00 +0000

The "core language network" consists of left frontal and temporal regions that are selectively engaged in linguistic processing. Whereas functional differences among these regions have long been debated, many accounts propose distinctions in terms of representational grain-size-e.g., words vs. phrases/sentences-or processing time-scale, i.e., operating on local linguistic features vs. larger spans of input. Indeed, the topography of language regions appears to overlap with a cortical hierarchy reported by Lerner et al. (2011) wherein mid-posterior temporal regions are sensitive to low-level features of speech, surrounding areas-to word-level information, and inferior frontal areas-to sentence-level information and beyond. However, the correspondence between the language network and this hierarchy of "temporal receptive windows" (TRWs) is difficult to establish because the precise anatomical locations of language regions vary across individuals. To directly test this correspondence,...

Impact of Vocal Tract Resonance on the Perception of Voice Quality Changes Caused by Varying Vocal Fold Stiffness

Fri, 9 Jun 2023 00:00:00 +0000

Experiments using animal and human larynx models are often conducted without a vocal tract. While it is often assumed that the absence of a vocal tract has only small effects on vocal fold vibration, it is not actually known how sound production and quality are affected. In this study, the validity of using data obtained in the absence of a vocal tract for voice perception studies was investigated. Using a two-layer self-oscillating physical model, three series of voice stimuli were created: one produced with conditions of left-right symmetric vocal fold stiffness, and two with left-right asymmetries in vocal fold body stiffness. Each series included a set of stimuli created with a physical vocal tract, and a second set created without a physical vocal tract. Stimuli were re-synthesized to equalize the mean F0 for each series and normalized for amplitude. Listeners were asked to evaluate the three series in a sort-and-rate task. Multidimensional scaling analysis was applied to...

Speaker discrimination performance for “easy” versus “hard” voices in style-matched and -mismatched speech

Thu, 8 Jun 2023 00:00:00 +0000

This study compares human speaker discrimination performance for read speech versus casual conversations and explores differences between unfamiliar voices that are "easy" versus "hard" to "tell together" versus "tell apart." Thirty listeners were asked whether pairs of short style-matched or -mismatched, text-independent utterances represented the same or different speakers. Listeners performed better when stimuli were style-matched, particularly in read speech-read speech trials (equal error rate, EER, of 6.96% versus 15.12% in conversation-conversation trials). In contrast, the EER was 20.68% for the style-mismatched condition. When styles were matched, listeners' confidence was higher when speakers were the same versus different; however, style variation caused decreases in listeners' confidence for the "same speaker" trials, suggesting a higher dependency of this task on within-speaker variability. The speakers who were "easy" or "hard" to "tell together" were not the same...

fMRI reveals language-specific predictive coding during naturalistic sentence comprehension

Thu, 8 Jun 2023 00:00:00 +0000

Much research in cognitive neuroscience supports prediction as a canonical computation of cognition across domains. Is such predictive coding implemented by feedback from higher-order domain-general circuits, or is it locally implemented in domain-specific circuits? What information sources are used to generate these predictions? This study addresses these two questions in the context of language processing. We present fMRI evidence from a naturalistic comprehension paradigm (1) that predictive coding in the brain's response to language is domain-specific, and (2) that these predictions are sensitive both to local word co-occurrence patterns and to hierarchical structure. Using a recently developed continuous-time deconvolutional regression technique that supports data-driven hemodynamic response function discovery from continuous BOLD signal fluctuations in response to naturalistic stimuli, we found effects of prediction measures in the language network but not in the domain-general...

Vocal Fundamental Frequency and Sound Pressure Level in Charismatic Speech: A Cross-Gender and -Language Study

Tue, 30 May 2023 00:00:00 +0000

OBJECTIVES/HYPOTHESES: Charismatic leaders use vocal behavior to persuade their audience, achieve goals, arouse emotional states, and convey personality traits and leadership status. This study investigates voice fundamental frequency (f0) and sound pressure level (SPL) in female and male French, Italian, Brazilian, and American politicians to determine which acoustic parameters are related to cross-gender and cross-cultural common vocal abilities, and which derive from culture-, gender-, and language-specific vocal strategies used to adapt vocal behavior to listeners' culture-related expectations. STUDY DESIGN: Speech corpora were collected for two formal communicative contexts (leaders address followers or other leaders) and one informal communicative context (dyadic interaction), based on the persuasive goals inherent in each context and on the relative status of the listeners and speakers. Leaders' acoustic voice profiles were created to show differences in f0 and SPL manipulation...

Young infants’ discrimination of subtle phonetic contrasts

Fri, 19 May 2023 00:00:00 +0000

It is generally accepted that infants initially discriminate native and non-native contrasts and that perceptual reorganization within the first year of life results in decreased discrimination of non-native contrasts, and improved discrimination of native contrasts. However, recent findings from Narayan, Werker, and Beddor (2010) surprisingly suggested that some acoustically subtle native-language contrasts might not be discriminated until the end of the first year of life. We first provide countervailing evidence that young English-learning infants can discriminate the Filipino contrast tested by Narayan et al. when tested in a more sensitive paradigm. Next, we show that young infants learning either English or French can also discriminate comparably subtle non-native contrasts from Tamil. These findings show that Narayan et al.'s null findings were due to methodological choices and indicate that young infants are sensitive to even subtle acoustic contrasts that cue phonetic...

Information Structure Preferences in Focus-Sensitive Ellipsis: How Defaults Persist

Mon, 15 May 2023 00:00:00 +0000

We compare the roles of overt accent and default focus marking in processing ellipsis structures headed by focus-sensitive coordinators (such as Danielle couldn't pass the quiz, let alone the final/Kayla). In a small auditory corpus study of radio transcripts, we establish that such structures overwhelmingly occur with contrastive pitch accents on the correlate and remnant ( the quiz and the final, or Danielle and Kayla), and that there is a strong bias to pair the remnant with the most local plausible correlate in production. In two auditory naturalness ratings experiments, we observe that marking a non-local correlate with contrastive pitch accent moderates, but does not fully overturn, the bias for local correlates in comprehension. We propose that the locality preference is due to a sentence-final default position for sentence accent, and that auditory processing is subject to "enduring focus," in which default positions for focus continue to influence the focus structure...

Comparing Measures of Voice Quality From Sustained Phonation and Continuous Speech

Fri, 5 May 2023 00:00:00 +0000

Purpose: The question of what type of utterance-a sustained vowel or continuous speech-is best for voice quality analysis has been extensively studied but with equivocal results. This study examines whether previously reported differences derive from the articulatory and prosodic factors occurring in continuous speech versus sustained phonation. Method: Speakers with voice disorders sustained vowels and read sentences. Vowel samples were excerpted from the steadiest portion of each vowel in the sentences. In addition to sustained and excerpted vowels, a 3rd set of stimuli was created by shortening sustained vowel productions to match the duration of vowels excerpted from continuous speech. Acoustic measures were made on the stimuli, and listeners judged the severity of vocal quality deviation. Results: Sustained vowels and those extracted from continuous speech contain essentially the same acoustic and perceptual information about vocal quality deviation. Conclusions: Perceived...

Abstract linguistic structure correlates with temporal activity during naturalistic comprehension

Wed, 3 May 2023 00:00:00 +0000

Neurolinguistic accounts of sentence comprehension identify a network of relevant brain regions, but do not detail the information flowing through them. We investigate syntactic information. Does brain activity implicate a computation over hierarchical grammars or does it simply reflect linear order, as in a Markov chain? To address this question, we quantify the cognitive states implied by alternative parsing models. We compare processing-complexity predictions from these states against fMRI timecourses from regions that have been implicated in sentence comprehension. We find that hierarchical grammars independently predict timecourses from left anterior and posterior temporal lobe. Markov models are predictive in these regions and across a broader network that includes the inferior frontal gyrus. These results suggest that while linear effects are wide-spread across the language network, certain areas in the left temporal lobe deal with abstract, hierarchical syntactic representation...

Modeling the voice source in terms of spectral slopesa)

Tue, 2 May 2023 00:00:00 +0000

A psychoacoustic model of the voice source spectrum is proposed. The model is characterized by four spectral slope parameters: the difference in amplitude between the first two harmonics (H1-H2), the second and fourth harmonics (H2-H4), the fourth harmonic and the harmonic nearest 2 kHz in frequency (H4-2 kHz), and the harmonic nearest 2 kHz and that nearest 5 kHz (2 kHz-5 kHz). As a step toward model validation, experiments were conducted to establish the acoustic and perceptual independence of these parameters. In experiment 1, the model was fit to a large number of voice sources. Results showed that parameters are predictable from one another, but that these relationships are due to overall spectral roll-off. Two additional experiments addressed the perceptual independence of the source parameters. Listener sensitivity to H1-H2, H2-H4, and H4-2 kHz did not change as a function of the slope of an adjacent component, suggesting that sensitivity to these components is robust....

The glottaltopogram: A method of analyzing high-speed images of the vocal folds

Sat, 29 Apr 2023 00:00:00 +0000

Laryngeal high-speed videoendoscopy is a state-of-the-art technique to examine physiological vibrational patterns of the vocal folds. With sampling rates of thousands of frames per second, high-speed videoendoscopy produces a large amount of data that is difficult to analyze subjectively. In order to visualize high-speed video in a straightforward and intuitive way, many methods have been proposed to condense the three-dimensional data into a few static images that preserve characteristics of the underlying vocal fold vibratory patterns. In this paper, we propose the "glottaltopogram," which is based on principal component analysis of changes over time in the brightness of each pixel in consecutive video images. This method reveals the overall synchronization of the vibrational patterns of the vocal folds over the entire laryngeal area. Experimental results showed that this method is effective in visualizing pathological and normal vocal fold vibratory patterns.

Keep it local (and final): Remnant preferences in “let alone” ellipsis

Tue, 18 Apr 2023 00:00:00 +0000

The let alone construction (John can't run a mile, let alone a marathon) differs from standard coordination structures (with and or but) by requiring ellipsis of the second conjunct--for example, a marathon is the remnant of an elided clause [[see text] a marathon]. In support of an ellipsis account, a corpus study of British and American English finds that let alone exhibits a Locality bias, as the second conjunct preferentially contrasts with the nearest lexical item of the same syntactic type. Two self-paced reading studies show that the Locality bias is active during online processing, but must be reconciled with indicators of semantic contrast and discourse information. Further, a sentence-rating study shows that the Locality bias interacts with a Finality bias that favours placing the let alone phrase at the end of a clause, which sometimes necessitates a nonlocal contrast. Together, the results show how a general bias in ellipsis for local contrasts is affected by discourse...

Acoustic voice variation in spontaneous speech

Wed, 14 Dec 2022 00:00:00 +0000

This study replicates and extends the recent findings of Lee, Keating, and Kreiman [J. Acoust. Soc. Am. 146(3), 1568-1579 (2019)] on acoustic voice variation in read speech, which showed remarkably similar acoustic voice spaces for groups of female and male talkers and the individual talkers within these groups. Principal component analysis was applied to acoustic indices of voice quality measured from phone conversations for 99/100 of the same talkers studied previously. The acoustic voice spaces derived from spontaneous speech are highly similar to those based on read speech, except that unlike read speech, variability in fundamental frequency accounted for significant acoustic variability. Implications of these findings for prototype models of speaker recognition and discrimination are considered.

Eighteen-month-old infants represent nonlocal syntactic dependencies

Mon, 8 Nov 2021 00:00:00 +0000

The human ability to produce and understand an indefinite number of sentences is driven by syntax, a cognitive system that can combine a finite number of primitive linguistic elements to build arbitrarily complex expressions. The expressive power of syntax comes in part from its ability to encode potentially unbounded dependencies over abstract structural configurations. How does such a system develop in human minds? We show that 18-mo-old infants are capable of representing abstract nonlocal dependencies, suggesting that a core property of syntax emerges early in development. Our test case is English wh-questions, in which a fronted wh-phrase can act as the argument of a verb at a distance (e.g., What did the chef burn?). Whereas prior work has focused on infants' interpretations of these questions, we introduce a test to probe their underlying syntactic representations, independent of meaning. We ask when infants know that an object wh-phrase and...

The puzzling nuanced status of who free relative clauses in English: a follow-up to Patterson and Caponigro (2015)

Mon, 16 Aug 2021 00:00:00 +0000

This squib challenges Patterson & Caponigro's (2015, this journal) claim that there are few acceptable free relative clauses with who. We show that free relatives with who are generally acceptable when they are ‘transparent’ free relatives or complements of a copula, and add further nuance to their findings concerning how the degree of acceptability of free relatives with who varies according to positional factors.

Stem similarity modulates infants' acquisition of phonological alternations

Phonemes have variant pronunciations depending on context. For instance, in American English, the [t] in pat [pæt] and the [d] in pad [pæd] are both realized with a tap [ɾ] when the -ing suffix is attached, [pæɾɪŋ]. We show that despite greater distributional and acoustic support for the [t]-tap alternation, 12-month-olds successfully relate taps to stems with a perceptually-similar final [d], not the dissimilar final-[t]. Thus, distributional learning of phonological alternations is constrained by infants' preference for the alternation of perceptually-similar segments. Further, the ability to relate variant surface forms emerges between 8- and 12-months. Our findings of biased learning provide further empirical support for a role for perceptual similarity in the acquisition of linguistically-relevant categories. We discuss the implications of our findings for phonological theory, language acquisition and models of the mental lexicon.

Against some approaches to long-distance agreement without AGREE

Thu, 22 Oct 2020 00:00:00 +0000

With the introduction of AGREE into Minimalism by Chomsky (2000), the relationship between the two elements in an agreement relationship went from being strictly local (Specifier-Head) to being unbounded (c-command with no intervening strong phase boundary) in order to accommodate long-distance agreement phenomena. Concern over the less restricted nature of the new approach led researchers to propose alternatives that eschewed the unbounded reach of AGREE, in the hope that a more restrictive theory might yet be salvaged. This chapter scrutinizes some of the most widely cited and fully developed of these alternative proposals (employing predicate inversion of expletives, restructuring, covert movement), applied to extensively studied spheres of data (English existentials, Icelandic agreement), and concludes that they are deeply, perhaps fatally, flawed. While Chomsky’s version of AGREE is far from providing a complete and satisfactory theory of agreement, it has yet to be shown...

Effects of consonantal constrictions on voice quality

Wed, 19 Aug 2020 00:00:00 +0000

A speech production experiment with electroglottography investigated how voicing is affected by consonants of differing degrees of constriction. Measures of glottal contact [closed quotient (CQ)] and strength of voicing [strength of excitation (SoE)] were used in conditional inference tree analyses. Broadly, the results show that as the degree of constriction increases, both CQ and SoE values decrease, indicating breathier and weaker voicing. Similar changes in voicing quality are observed throughout the course of the production of a given segment. Implications of these results for a greater understanding of source-tract interactions and for the phonological notion of sonority are discussed.

Quantifying Sources of Variability in Infancy Research Using the Infant-Directed-Speech Preference

Mon, 17 Aug 2020 00:00:00 +0000

Psychological scientists have become increasingly concerned with issues related to methodology and replicability, and infancy researchers in particular face specific challenges related to replicability: For example, high-powered studies are difficult to conduct, testing conditions vary across labs, and different labs have access to different infant populations. Addressing these concerns, we report on a large-scale, multisite study aimed at (a) assessing the overall replicability of a single theoretically important phenomenon and (b) examining methodological, cultural, and developmental moderators. We focus on infants’ preference for infant-directed speech (IDS) over adult-directed speech (ADS). Stimuli of mothers speaking to their infants and to an adult in North American English were created using seminaturalistic laboratory-based audio recordings. Infants’ relative preference for IDS and ADS was assessed across 67 laboratories in North America, Europe, Australia, and Asia using...

Acceptability ratings cannot be taken at face value

Wed, 27 May 2020 00:00:00 +0000

This chapter addresses how linguists’ empirical (syntactic) claims should be tested with non-linguists. Recent experimental work attempts to measure rates of convergence between data presented in journal articles and the results of large surveys. Three follow-up experiments to one such study are presented. It is argued that the original method may underestimate the true rate of convergence because it leaves considerable room for naïve subjects to give ratings that do not reflect their true acceptability judgments of the relevant structures. To understand what can go wrong, the experiments were conducted in two parts. The first part had visually presented sentences rated on a computer, replicating previous work. The second part was an interview where the experimenter asked the participants about the ratings they gave to particular items, in order to determine what interpretation or parse they had assigned, whether they had missed any critical words, and so on.

Toward a unified theory of voice production and perception

Sat, 16 May 2020 00:00:00 +0000

At present, two important questions about voice remain unanswered: When voice quality changes, what physiological alteration caused this change, and if a change to the voice production system occurs, what change in perceived quality can be expected? We argue that these questions can only be answered by an integrated model of voice linking production and perception, and we describe steps towards the development of such a model. Preliminary evidence in support of this approach is also presented. We conclude that development of such a model should be a priority for scientists interested in voice, to explain what physical condition(s) might underlie a given voice quality, or what voice quality might result from a specific physical configuration.

Intervention in tough-constructions revisited

Sat, 16 May 2020 00:00:00 +0000

AbstractIn this paper, we subject to closer scrutiny one particularly influential recent argument in favour of the long-movement analysis oftough-constructions. Hartman (2011, 2012a, 2012b) discovered that experiencer PPs lead to ungrammaticality intough-constructions, but not in expletive constructions. He attributes this ungrammaticality to defective intervention of A-movement, a movement step crucially postulated only in the long-movement analysis. He takes this as evidence thattough-constructions are derived via long movement. We make the novel observation that a PP intervention effect analogous to that intough-constructions also arises in constructions that do not involve A-movement, namely pretty-predicate constructions and gapped degree phrases. Consequently, the intervention effect does not provide an argument for an A-movement step intough-constructions or for the long-movement analysis, but rather for the base-generation analysis. We develop a uniform account of the...

Improving language mapping in clinical fMRI through assessment of grammar

Sat, 16 May 2020 00:00:00 +0000

INTRODUCTION: Brain surgery in the language dominant hemisphere remains challenging due to unintended post-surgical language deficits, despite using pre-surgical functional magnetic resonance (fMRI) and intraoperative cortical stimulation. Moreover, patients are often recommended not to undergo surgery if the accompanying risk to language appears to be too high. While standard fMRI language mapping protocols may have relatively good predictive value at the group level, they remain sub-optimal on an individual level. The standard tests used typically assess lexico-semantic aspects of language, and they do not accurately reflect the complexity of language either in comprehension or production at the sentence level. Among patients who had left hemisphere language dominance we assessed which tests are best at activating language areas in the brain. METHOD: We compared grammar tests (items testing word order in actives and passives, wh-subject and object questions, relativized...

Polarized Variation

Wed, 13 May 2020 00:00:00 +0000

In cases of exceptionality, there are usually many words that behave regularly, a smaller number that behave irregularly (the exceptions), and perhaps an even smaller number whose behavior varies. This paper presents several examples of exceptionality and variation that are polarized in this way: most items exhibit one behavior or the other consistently, with only a minority of items showing variation. The result is a U-shaped histogram of behavior rates. In some cases, this requires listing of surprisingly long units. There are, however, some cases of bell-shaped histograms, where most items show variation, and only a minority are consistent. Some simple simulations are presented to show how polarized variation can result when variation is between two categorical outcomes, and both types of variation can result when variation is along a phonetic continuum.

Gotta catch 'em all: Skills grading in undergraduate linguistics

Fri, 6 Mar 2020 00:00:00 +0000

Dissatisfied with traditional grading, we developed a grading system to directly assess whether students have mastered course material. We identified the set of skills students need to master in a course and provided multiple opportunities for students to demonstrate mastery of each skill. We describe in detail how we implemented the system for two undergraduate courses, Introductory Phonetics and Phonology I. Our goals were to decrease student stress, increase student learning and make students’ study efforts more effective, increase students’ metacognitive awareness, promote a growth mindset, encourage students to aim for mastery rather than partial credit, be fairer to students facing structural and institutional disadvantages, reduce our time spent on grading, and facilitate complying with new accreditation requirements. Our own reflections and student feedback indicate that many of these goals were met.

Non-native contrasts in Tongan loans

Fri, 6 Mar 2020 00:00:00 +0000

We present three case studies of marginal contrasts in Tongan loans from English, working with data from three speakers. Although Tongan lacks contrasts in stress or in CC vs. CVC sequences, secondary stress in loans is contrastive, and is sensitive to whether a vowel has a correspondent in the English source word; vowel deletion is also sensitive to whether a vowel is epenthetic as compared to the English source; and final vowel length is sensitive to whether the penultimate vowel is epenthetic, and if not, whether it corresponds to a stressed or unstressed vowel in the English source. We provide an analysis in the multilevel model of Boersma (1998) and Boersma & Hamann (2009), and show that the loan patterns can be captured using only constraints that plausibly are needed for native-word phonology, including constraints that reflect perceptual strategies.

Cue-shifting between acoustic cues: Evidence for directional asymmetry

Fri, 17 Jan 2020 00:00:00 +0000

Previous research shows that experience with co-varying cues is neither sufficient nor necessary for listeners to integrate them perceptually. Auditory Enhancement theorists explain this by positing that listeners integrate two cues more readily if the cues enhance each other's percept. To isolate the role of enhancement from that of experience, we forced English adult listeners to shift attention between two enhancing cues that they do not use phonemically, pitch and breathiness, by reversing the informativeness of the two cues in a cue weighting experiment. Listeners were able to shift attention from pitch to breathiness and vice versa if the two cues were in an enhancing relation. When this relationship was reversed, listeners could shift attention from pitch to breathiness but not in the opposite direction. Clearly, both the change in informativeness and the enhancing properties of the cues influenced the listeners’ re-weighting of these cues. However, the directional asymmetry...

Lexical stress constrains English-learning infants’ segmentation in a non-native language

Fri, 17 Jan 2020 00:00:00 +0000

Infants' ability to segment words in fluent speech is affected by their language experience. In this study we investigated the conditions under which infants can segment words in a non-native language. Using the Head-turn Preference Procedure, we found that monolingual English-learning 8-month-olds can segment bisyllabic words in Spanish (trochees and iambs) but not French (iambs). Our results are incompatible with accounts that rely on distributional learning, language rhythm similarity, or target word prosodic shape alone. Instead, we show that monolingual English-learning infants are able to segment words in a non-native language as long as words have stress, as is the case in English. More specifically, we show that even in a rhythmically different non-native language, English-learning infants can find words by detecting stressed syllables and treating them as word onsets or offsets.

Acoustic voice variation within and between speakers

Fri, 8 Nov 2019 00:00:00 +0000

Little is known about the nature or extent of everyday variability in voice quality. This paper describes a series of principal component analyses to explore within- and between-talker acoustic variation and the extent to which they conform to expectations derived from current models of voice perception. Based on studies of faces and cognitive models of speaker recognition, the authors hypothesized that a few measures would be important across speakers, but that much of within-speaker variability would be idiosyncratic. Analyses used multiple sentence productions from 50 female and 50 male speakers of English, recorded over three days. Twenty-six acoustic variables from a psychoacoustic model of voice quality were measured every 5 ms on vowels and approximants. Across speakers the balance between higher harmonic amplitudes and inharmonic energy in the voice accounted for the most variance (females = 20%, males = 22%). Formant frequencies and their variability accounted for an...

Why do children pay more attention to grammatical morphemes at the ends of sentences?

Tue, 6 Nov 2018 00:00:00 +0000

Children pay more attention to the beginnings and ends of sentences rather than the middle. In natural speech, ends of sentences are prosodically and segmentally enhanced; they are also privileged by sensory and recall advantages. We contrasted whether acoustic enhancement or sensory and recall-related advantages are necessary and sufficient for the salience of grammatical morphemes at the ends of sentences. We measured 22-month-olds' listening times to grammatical and ungrammatical sentences with third person singular -s. Crucially, by cross-splicing the speech stimuli, acoustic enhancement and sensory and recall advantages were fully crossed. Only children presented with the verb in sentence-final position, a position with sensory and recall advantages, distinguished between the grammatical and ungrammatical sentences. Thus, sensory and recall advantages alone were necessary and sufficient to make grammatical morphemes at ends of sentences salient. These general processing constraints...

Beyond trochaic shortening: A survey of Central Pacific languages

Mon, 11 Jun 2018 00:00:00 +0000

An underlying form like /maːli/ is problematic for a stress system requiring word-final, bimoraic trochees. The grammar must sacrifice word-finality or bimoraicity, [(máː)li] or [(máːli)] (tolerating HL#); place stress on the second half of the long vowel, [ma(áli)] (breaking); or shorten the vowel, [(máli)] (trochaic shortening). This article surveys the Central Pacific language family, which hosts the most famous cases of breaking (Tongan) and trochaic shortening (Fijian), and finds that while trochaic shortening is poorly attested, breaking and tolerance are common. There are three findings of theoretical interest. First, length alternations suggest it is difficult to learn contrastive information that is absent in the core member of the morphological paradigm. Second, lexicalization of whole words is a possible response to this difficulty. Third, there is divergence between a language’s root phonotactics and its alternations.

The word-level prosody of Samoan*

Tue, 10 Apr 2018 00:00:00 +0000

This paper documents and analyses stress and vowel length in Samoan words. The domain of footing, the Prosodic Word, appears to be a root and cohering suffixes; prefixes and most disyllabic suffixes form a separate domain. Vowel sequences that disrupt the normal stress pattern require constraints matching sonority prominence to metrical prominence, sensitive to degree of mismatch and to the number of vowels involved. Two suffixes unexpectedly have an idiosyncratic footing constraint, observable only in a limited set of words. We also discuss trochaic shortening and its asymmetrical productivity, and the marginal contrastiveness of some features in loans. While Samoan does not appear to be typologically unusual, it does offer arguments (i) in favour of alignment constraints on Prosodic Words rather than only on feet directly, and (ii) against simple cyclicity. Some of the strongest evidence comes from stress patterns of the rich inventory of phonotactically licit vowel sequences.
