The that-trace effect and island boundary-gap effect are the same: Demonstrating equivalence with null hypothesis significance testing and psychometrics
This paper demonstrates a novel approach in experimental syntax, leveraging psychometric methods to resolve a decades-old puzzle. Specifically, gaps in subject position are more acceptable than gaps in object position in non-islands, while the reverse is true in islands (the Island Boundary-Gap Effect). Attempts at explaining this asymmetry generally attribute it to a violation of the same constraint that renders gaps unacceptable after the overt complementizer `that' (the That-Trace Effect). However, the two effects involve distinct syntactic structures, and there is no a priori reason to believe they are the same beyond the elegance of a unified account. One limitation has been the difficulty of testing for equivalence in the Null Hypothesis Significance Testing framework: when two constructs behave similarly, it generally constitutes an uninterpretable null result. Experiments 1 and 2 use standard experimental methods to circumvent this problem, but ultimately provide evidence that is at best just consistent with equivalence. Experiment 3 demonstrates a novel approach which shows that individual differences in the That-Trace Effect correlate with individual differences in the Island Boundary-Gap Effect, after removing correlated variance from carefully-chosen controls. This psychometric approach provides positive evidence that the two effects do indeed derive from the same underlying phenomenon.

Is reanalysis selective when regressions are consciously controlled?
The selective reanalysis hypothesis of Frazier and Rayner (1982) states that when faced with the need to reanalyze a syntactic ambiguity, readers direct their eyes towards the region in the sentence inducing the ambiguity (e.g., Since Jay always jogs a mile seems like a short distance to him). Given the mixed evidence for this proposal in the literature, we investigated the possibility that selective reanalysis is tied to conscious awareness of the garden-path effect. To this end, we adapted the well-known self-paced reading paradigm to allow for regressive as well as progressive key presses. Assuming that regressions in such a paradigm are consciously controlled, we found no evidence for selective reanalysis, but rather for occasional extensive, heterogeneous rereading of garden-path sentences. We discuss the implications of our findings for the selective reanalysis hypothesis, the role of awareness in sentence processing, as well as the usefulness of the bidirectional self-paced reading method for sentence processing research.

Lexicalization in the developing parser
We use children's noun learning as a probe into the nature of their syntactic prediction mechanism and the statistical knowledge on which that prediction mechanism is based. We focus on verb-based predictions, considering two possibilities: children's syntactic predictions might rely on distributional knowledge about specific verbs–i.e. they might be lexicalized–or they might rely on distributional knowledge that is general to all verbs. In an intermodal preferential looking experiment, we establish that verb-based predictions are lexicalized: children encode the syntactic distributions of specific verbs and use those distributions to make predictions, but they do not assume that these can be assumed of verbs in general.

The processing of ambiguous pronominal reference is sensitive to depth of processing
Previous studies on the processing of ambiguous pronominal reference have led to contradictory results: some suggested that ambiguity may hinder processing (Stewart, Holler, & Kidd, 2007), while others showed an ambiguity advantage (Grant, Sloggett, & Dillon, 2020) similar to what has been reported for structural ambiguities. This study provides a conceptual replication of Stewart et al. (2007, Experiment 1), to examine whether the discrepancy in earlier results is caused by the processing depth that participants engage in (cf. Swets, Desmet, Clifton, & Ferreira, 2008). We present the results from a word-by-word self-paced reading experiment with Dutch sentences that contained a personal pronoun in an embedded clause that was either ambiguous or disambiguated through gender features. Depth of processing of the embedded clause was manipulated through offline comprehension questions. The results showed that the difference in reading times for ambiguous versus unambiguous sentences depends on the processing depth: a significant ambiguity penalty was found under deep processing but not under shallow processing. No significant ambiguity advantage was found, regardless of processing depth. This replicates the results in Stewart et al. (2007) using a different methodology and a larger sample size for appropriate statistical power. These findings provide further evidence that ambiguous pronominal reference resolution is a flexible process, such that the way in which ambiguous sentences are processed depends on the depth of processing of the relevant information. Theoretical and methodological implications of these findings are discussed.

Agreement attraction error and timing profiles in continuous speech
Studies of agreement attraction in language production have shown that speakers systematically produce verb agreement errors in the presence of a local noun whose features differ from that of the agreement controller. However, in attraction experiments, these errors only ever occur in a subset of trials. In the present study, we applied a naturalistic scene-description paradigm to investigate how attraction affects the distribution of errors and the time-course of correctly inflected verbs. We conducted our experiment both in the lab and in an unsupervised web-based setting. The results were strikingly similar across the experimental settings for both the error and timing analyses, demonstrating that it is possible to conduct production experiments via the internet with a high level of similarity to those done in the lab. The experiments replicated the basic number attraction effect, though they elicited comparable interference from both singular and plural local nouns, challenging common assumptions about a strong plural markedness effect in attraction. We observed slowdowns before correct verbs that paralleled the distribution of agreement errors, suggesting that the process resulting in attraction can be active even when no error is produced. Our results are easily captured by a model of agreement attraction in which errors arise at the point of computing agreement, rather than reflecting earlier errors made during initial encoding of the subject number.

(How) Visual properties affect the perception and description of transitive events
In a non-verbal aesthetic judgement task and a pre-registered production task, we tested how the orientation of the patient relative to the agent in a visual scene affects the perception and description of the depicted transitive event. Previous research has shown that a visual property like the position of the patient relative to the agent can affect speakers’ verbalization of events. Here, we investigated whether orientation constitutes another factor besides position that affects scene description. While speakers of German displayed an overall preference for scenes in which agent and patient faced each other, these scenes needed more time for sentence planning than the same scenes that showed the patient looking in the same direction and thus away from the agent. Moreover, we elicited more patient-initial sentences for face-to-face scenes than for same-direction scenes. The increase in patient-initial sentences was comparable to the increase in patient-initial sentences for scenes with left-positioned patients as compared to right-positioned patients. Based on our findings, we argue that manipulations of both position and orientation can change the prominence of the patient. The more prominent the patient (facing the agent, being placed to the left of the agent), the more likely speakers are to choose the patient as the sentence-initial subject. Hence, subtle changes of visual properties may affect not only how speakers perceive an event but also how they describe an event. Our findings are of relevance for a range of tasks that use visual materials.

Why bother? What our eyes tell about psych verb (non) causative constructions
We present an eyetracking study that investigates how linking is achieved during real-time comprehension of Spanish sentences with causative psych verbs and alternative case marking. This group of verbs lead to verbs’ argument structures that require direct or inverse syntax-to-semantics linking according to the type of case marking assigned to their object. The study aimed at disentangling whether processing inverse linking was more costly than direct linking, and exploring how incremental argument interpretation takes place when lexemes that accept several case markings are used. Results showed that during incremental comprehension, inverse linking is more difficult than direct linking, irrespective of word order. As for argument interpretation, the current study partially replicated the results of previous studies conducted in this language using different verb types. Findings are discussed under the light of different psycholinguistic models addressing case marking processing and incremental linking.

Comparing infrared and webcam eye tracking in the Visual World Paradigm
Visual World eye tracking is a temporally fine-grained method of monitoring attention, making it a popular tool in the study of online sentence processing. Recently, while infrared eye tracking was mostly unavailable, various web-based experiment platforms have rapidly developed webcam eye tracking functionalities, which are now in urgent need of testing and evaluation. We replicated a recent Visual World study on the incremental processing of verb aspect in English using ‘out of the box’ webcam eye tracking software (jsPsych; de Leeuw, 2015) and crowdsourced participants, and fully replicated both the offline and online results of the original study. We furthermore discuss factors influencing the quality and interpretability of webcam eye tracking data, particularly with regards to temporal and spatial resolution; and conclude that remote webcam eye tracking can serve as an affordable and accessible alternative to lab-based infrared eye tracking, even for questions probing the time-course of language processing.

Complexity vs. salience of alternatives in implicature: A cross-linguistic investigation
Scalar implicature depends on the activation of alternatives. For instance, in English, finger implicates 'not thumb', suggesting that thumb is an activated alternative. Is this because it is more specific (Quantity) and equally short (Manner)? Indeed, toe doesn't imply 'not big toe', perhaps because big toe is longer. As L. Horn points out, this Quantity/Manner explanation predicts that if English had the simplex Latin word pollex meaning 'thumb or big toe', then the asymmetry would disappear. But would it suffice for that word to exist in the language, or would the word also have to be sufficiently salient? We explore this question in four languages that are sometimes said to lack a single-word alternative for thumb: Spanish (which does have pulgar 'thumb or big toe' (< pollex), though it is a non-colloquial form), Russian, Persian, and Arabic. To gauge the salience of various ways of describing digits, we use a fill-in-the-blank production task. We then measure the availability of implicatures using a forced choice comprehension task. We find cross-linguistic differences in implicature, and moreover that implicature calculation tracks production probabilities more closely than structural complexity of the alternatives. A comparison between two Rational Speech Act models—one in which the speaker replicates our production data and a standard one in which the speaker chooses based on a standard cost/accuracy trade-off—shows that comprehension is more closely tied to production probability than to the complexity of alternatives.

Cross-lingual priming of cognates and interlingual homographs from L2 to L1
The aim of the current study was to explore whether lexical processing in a bilingual’s first language (L1) can be influenced by recent experience in their second language (L2). We focussed on word forms that exist in both their languages, and have either the same meaning (cognates) or a different meaning (interlingual homographs). Our previous experiments provided evidence for the reverse form of cross-lingual priming: processing of interlingual homographs in a bilingual’s L2 is delayed by recent experience with these words in their L1, while processing of cognates can be speeded up (Poort et al., 2016; Poort & Rodd, 2019b). In the current experiment, Dutch–English bilinguals (n = 106) first encountered cognates (n = 50), interlingual homographs (n = 50) and translation equivalents (n = 50) embedded in English sentences. After a 15 minute delay they made Dutch semantic relatedness judgements to these target words. Significant cross-lingual priming was observed for the interlingual homographs, but not for the cognates. The magnitude of this L2-to-L1 priming effect did not differ from our earlier L1-to-L2 priming effect (Poort & Rodd, 2019b). We also addressed subsidiary questions regarding the (unprimed) processing of cognates and interlingual homographs. Consistent with our previous findings (Poort & Rodd, 2019b), we found a large interlingual homograph inhibition effect in an L1 semantic relatedness task, but no evidence for a cognate facilitation effect in this task. These findings together emphasise the high level of cross-lingual interaction in the bilingual mental lexicon, especially in language-switching contexts.

The role of prosodic focus in the reanalysis of garden path sentences: Depth of semantic processing impedes the revision of an erroneous local analysis
Research on post-repair representations of garden path sentences has found that readers systematically arrive at misinterpretations even after displaying evidence of reanalysis (Christianson et al., 2001; Ferreira et al., 2001). These comprehension errors have been attributed to the semantic interpretation associated with the incorrect parse persisting past disambiguation, but less is known about the mechanism driving this phenomenon (Sturt, 2007; Slattery et al., 2013). A speeded auditory comprehension experiment examined the depth of semantic processing as an independent influence on the strength of semantic persistence, drawing on known effects of pitch accent on the processing of focus-related semantic meaning (Fraundorf et al., 2010). Participants heard garden path sentences with early/late-closure ambiguity (e.g., While Anna dressed the baby stopped crying) with a sharply rising pitch accent on either the unambiguous adjunct subject or the ambiguously transitive adjunct verb, followed by a comprehension question that probed whether the incorrect late-closure analysis persisted. Since the pitch accent is often a strong cue for semantic focus when it occurs in prosodically marked phrase-medial positions, we reasoned that a deeper semantic processing would be facilitated for the late-closure analysis only when the verb receives a pitch accent. Findings indicate that a pitch accent on the verb significantly decreased accuracy without a corresponding increase on response time, suggesting that a deeper semantic processing of the erroneous parse can strengthen its resistance to revision without necessarily interfering with the process of structure-building.

The effect of speaker reliability on adult cross-situational word learning
Word learning is guided by the statistical co-occurrence between spoken words and potential referents, through which learners gradually map labels to objects across situations. Given that word learning does not occur in a vacuum, rather in a communicative context, it is relevant to evaluate the role that speakers play. Because we do not evaluate the information provided by every person equally, it is reasonable to think that someone who makes lexical errors is not a reliable speaker from whom to learn new words. The current study focuses on speaker reliability in adult cross-situational word learning (CSWL). In two experiments we investigated the extent to which adults attend to the reliability of the speaker and how this affects word learning in a CSWL task. We varied the consistency with which a speaker mapped novel words to familiar objects. We hypothesized (1) that the speakers’ reliability would be judged differently depending on their past object-labeling accuracy, and (2) that new words would be more difficult to learn when presented by an unreliable speaker. Experiment 1 shows that the unreliable speaker was assessed as less reliable, compared to the reliable speaker, but this effect disappeared in Experiment 2, when participants were taught new words by two speakers, a reliable and an unreliable one. Furthermore, we found no evidence to support the hypothesis that being exposed to an unreliable speaker impairs CSWL in adults. We discuss the relevance of these findings and the importance of further research on the role of speaker reliability in CSWL.

Children’s acquisition of new/given markers in English, Hindi, Mandinka and Spanish: Exploring the effect of optionality during grammaticalization
We investigated the effect of optionality on the acquisition of new/given markers, with a special focus on grammaticalization as a stage of optional use of the emerging form. To this end, we conducted a narrative-elicitation task with 5-year-old children and adults across four typologically-distinct languages with different new/given markers: English, Hindi, Mandinka and Spanish. Our starting assumption was that the Hindi numeral ‘ek’ (one) is developing into an indefinite article, which should delay children’s acquisition because of its optional use to introduce discourse referents. Supporting the Optionality Hypothesis, Experiment 1 revealed that obligatory markers are acquired earlier than optional markers. Experiment 2 focused on Hindi and showed that 10-year-old children’s use of ‘ek’ to introduce discourse characters was higher than 5-year-olds’ and comparable to adults’, replicating this pattern of results in two different cities in Northern India. Lastly, a follow-up study showed that Mandinka-speaking children and adults made use of all available discourse markers when tested on a familiar story, rather than with pictorial prompts, highlighting the importance of using culturally-appropriate methods of narrative elicitation in cross-linguistic research. We conclude by discussing the implications of article grammaticalization for common ground management in a speech community.

Processing reflexive pronouns when they don’t announce themselves
In two experiments we investigated the comprehension of pronoun forms in Chamorro, a verb-initial Austronesian language that does not distinguish morphologically between reflexive anaphors and pronominals. In Experiment 1, on object pronouns, we found that comprehenders had a preference for reflexive interpretations despite the fact that the pronoun form was not morphologically marked as reflexive. In Experiment 2, on possessor pronouns, we found that this preference was much weaker. We conclude that when a morphological distinction between reflexive anaphors and pronominals is absent, comprehenders do prefer to assign reflexive interpretations. However, this pressure is defeasible and moderated by morphosyntactic and semantic factors, such as the competition between null and overt pronoun forms and the verb’s argument structure.

Conscious rereading is confirmatory: Evidence from bidirectional self-paced reading
Rereading during sentence processing can be confirmatory, in which case it serves to increase readers' certainty in their current interpretation, or it can be revisionary, in which case it serves to correct a misinterpretation (Christianson, Luke, Hussey, & Wochna, 2017). The distinction is particularly relevant in garden-path sentences, which have been argued to trigger revisionary rereading (Frazier & Rayner, 1982). In two web-based experiments that compare garden-path sentences with other linguistic constructions, we investigate deliberate rereading in the recently-proposed bidirectional self-paced reading (BSPR) paradigm (Paape & Vasishth, 2022). Our results show evidence for selective rereading only in very difficult garden-path sentences. Additionally, our results suggest that conscious, selective rereading is confirmatory: Readers find garden-path sentences less rather than more acceptable after selective rereading, suggesting that they reread either to confirm their initial analysis or to confirm the perceived ungrammaticality of the sentence. We discuss the role of conscious awareness in dealing with different types of linguistic inconsistency.

Syntactic and semantic mismatches in English number agreement
In English, it is possible for a morphologically singular collective noun like government to control both singular (syntactic) agreement and plural (semantic) agreement in the same sentence (e.g. The government has praised themselves). It has been claimed that sentences with the opposite pattern of agreeing elements are ungrammatical (e.g. *The government have praised itself), and there is a corresponding asymmetry in corpus frequencies of these two configurations. Across two acceptability judgement experiments, we show that the acceptability contrast is affected by the relative order of the two agreeing elements, with degraded acceptability in the case where the first agreeing element shows plural agreement and the second shows singular agreement, relative to the opposite configuration. This pattern is found both when the agreeing verb precedes the reflexive, and when the reflexive precedes the verb. Overall, the results suggest that the initial formation of a semantic agreement dependency between an agreement target and a collective controller makes subsequent morpho-syntactic agreement with the same controller less accessible. We argue that any theoretical account of these results would require an important role for incremental processing.

Does nonbinary they inherit the binary pronoun production system?
The English pronoun system is undergoing a change in progress as singular they is used more frequently to refer to specific individuals, especially those who identify as nonbinary. How does this change affect the language production system? Research has shown that the production of he/she pronouns is supported by salient discourse status and inhibited in contexts where the pronoun would be ambiguous. In an analysis of naturally-occurring written texts, we test whether they production patterns with he/she production, controlling for discourse context. Results show that the overall rate of pronoun use is lower for references to nonbinary individuals than for references to binary individuals. This difference is not explained by the potential ambiguity of a referent in context. We speculate that relative unfamiliarity with nonbinary they and nonbinary gender may inhibit the activation of they during production, or may lead writers to avoid using a form that may not be familiar to their addressees.

Prediction in the maze: Evidence for probabilistic pre-activation from the English a/an contrast
The idea that comprehenders predict upcoming linguistic content has become core to many theories of language processing. Experimental studies exploiting morphosyntactic and phonotactic constraints on a word form preceding a high cloze target word have been key to underpinning predictive accounts of comprehension, but investigating these tight sequential contrasts with traditional behavioral methods is difficult. The maze task, with its more focal measure of incremental processing, may provide a cheap and easy methodology to study early cues to prediction. An experiment investigating the a/an contrast (DeLong, Urbach, & Kutas, 2005; Nieuwland, et al., 2018) using A-maze (Boyce, Futrell, & Levy, 2020) finds that unexpected articles, as well as nouns, elicit slower focal response times. Response times are also shown to be inversely related to noun cloze probabilities, with slower responders showing larger effects of expectation. This study demonstrates that the maze task can be sensitive to expectation and is a useful alternative methodology for investigating prediction in comprehension.
