Less studied is gene-by-environment interplay with income inequality as the environmental exposure. Here, we examine the association between childhood exposure to inequality and individual differences in adult depressive symptoms, testing for moderation of genetic influences by inequality using polygenic indices for major depressive disorder, as well as twin models. METHODS: The research participants were 69,924 members of twin studies from four developed countries, born between 1893 and 1979, aged 22-103 years at depressive symptom assessment. Genotyping was available for 6,256 participants. Income inequality was operationalized as share of income accruing to the top 1% for each country when the participants were between age 5 and 15 years. RESULTS: Childhood income inequality was associated with depressive symptom scores in adulthood, adjusting... https://escholarship.org/uc/item/68c924z0 Wed, 17 Jun 2026 00:00:00 +0000 Petkus, Andrew J Reynolds, Chandra A https://orcid.org/0000-0001-6502-7173 Finch, Brian K Thomas, Kyla Beam, Christopher R Catts, Vibeke S Ericsson, Malin Finkel, Deborah G Franz, Carol E https://orcid.org/0000-0002-8987-1755 Kremen, William S Larsen, Lisbeth Aagaard Martin, Nicholas G McGue, Matt Mosing, Miriam A Neiderhiser, Jenae M Nygaard, Marianne Pedersen, Nancy L Thalamuthu, Anbupalam Whitfield, Keith E Gatz, Margaret Consortium, the IGEMS https://escholarship.org/uc/item/9th8c22k Cognitive decline, in healthy older adults without cognitive impairment or dementia, has been associated with numerous microstructural alterations in brain tissue using magnetic resonance imaging (MRI). Prior studies have primarily linked age-related cognitive decline to alterations in white matter tissue, but methodological advances in diffusion-weighted imaging (dMRI) data acquisition and modeling now allow for these analyses to be extended to gray matter tissue. Here, using a sample of 152 healthy adults (18-88 years of age), we used a multicompartment dMRI model to assess (1) age-related differences in gray matter microstructure of functionally defined networks and (2) whether microstructural alterations accounted for age-related differences in episodic memory and speed-dependent fluid cognition. We observed significant age-related alterations in gray matter tissue in the form of nonlinear, age-related increases and decreases in intracellular and dispersed diffusion, respectively,... https://escholarship.org/uc/item/9th8c22k Thu, 11 Jun 2026 00:00:00 +0000 Merenstein, Jenna L Bennett, Ilana J https://orcid.org/0000-0002-5330-4679 Madden, David J https://escholarship.org/uc/item/8f63b4kw Adults of all ages are worse at recognizing pairs of items that were previously seen together relative to the individual items, and this paired-associative memory deficit is exacerbated in aging. Less is known about memory for higher associative loads, which place greater demands on binding processes that link items into a cohesive memory trace, among other processes (e.g., working memory, recollection). In this study, adults across the lifespan (n&nbsp;=&nbsp;250, 18-78&nbsp;years) completed a novel recognition task in which they studied word pairs, triplets, and quadruplets and were tested on their memory for repeated, recombined, and novel word sets. Associative memory deficits were seen in adults of all ages as fewer correct responses to repeated sets (hits), more incorrect responses to recombined sets (recombined false alarm, FA), and larger differences between these measures (associative memory) at higher set sizes.

Despite frailty's prevalence in older adults, there is limited research on its neural substrates. Methods: In this study, we used connectome-based predictive modeling (CPM) to find a linear relationship between task-based connectomes taken from tasks that involved similar handgrip manipulations and a separate measure of physical frailty: the maximum grip strength in older adults. Results: We observed that the task-based connectomes were able to explain individual differences in grip strength, with the Subcortical and Cerebellum network, particularly the caudate nucleus functional connectivity, being the strongest predictor. Discussion: These findings demonstrate that task-based functional connectomes can serve as personalized markers for predicting individual... https://escholarship.org/uc/item/7hn5j4hf Thu, 11 Jun 2026 00:00:00 +0000 Ghaffari, Amin Abouzaki, Majd Romero, Yasmine Sun, Andrew Seitz, Aaron https://orcid.org/0000-0003-4936-9303 Langley, Jason Bennett, Ilana J https://orcid.org/0000-0002-5330-4679 Hu, Xiaoping https://escholarship.org/uc/item/6bh2b8ms The presence of neurofibrillary tangles containing hyper-phosphorylated tau is a characteristic of Alzheimer's disease (AD) pathology. The positron emission tomography (PET) radioligand sensitive to tau neurofibrillary tangles (¹⁸F-AV1451) also binds with iron. This off-target binding effect may be enhanced in older adults on the AD spectrum, particularly those with amyloid-positive biomarkers. Here, we examined group differences in ¹⁸F-AV1451 PET after controlling for iron-sensitive measures from magnetic resonance imaging (MRI) and its relationships to tissue microstructure and cognition in 40 amyloid beta positive (Aβ+) individuals, 20 amyloid beta negative (Aβ-) with MCI and 31 Aβ- control participants. After controlling for iron, increased ¹⁸F-AV1451 PET uptake was found in the temporal lobe and hippocampus of Aβ+ participants compared to Aβ- MCI and control participants.

The current study extends these findings to human cognitive aging and suggests that magnetic resonance imaging (MRI) techniques like quantitative relaxometry can be used to study iron and its effects in vivo . The effects of iron on microstructure and memory performance were examined using a combination of quantitative relaxometry and multi-compartment diffusion imaging in 35 young (21.06 ± 2.18 years) and 28 older (72.58 ± 6.47 years) adults, who also completed a memory task. Replicating past work, results revealed age-related increases in iron content (R 2 *) and diffusion, and decreases in memory performance. Independent of age group, iron content was significantly related to restricted (intracellular) diffusion in regions with low-moderate iron (hippocampus, caudate) and to all diffusion metrics in... https://escholarship.org/uc/item/3bv183c6 Thu, 11 Jun 2026 00:00:00 +0000 Venkatesh, Anu Daugherty, Ana M Bennett, Ilana J https://orcid.org/0000-0002-5330-4679 https://escholarship.org/uc/item/2g16p0xp This study aimed to provide a complete characterization of age group differences in cortical lobar, hippocampal, and subcortical gray matter microstructure using a multi-compartment diffusion-weighted MRI (DWI) approach with parameters optimized for gray matter (Neurite Orientation Dispersion and Density Imaging, NODDI). 76 younger (undergraduate students) and 64 older (surrounding communities) adults underwent diffusion-, T1-, and susceptibility-weighted MRI. Results revealed eight unique patterns across the 12 regions of interest in the relative direction and magnitude of age effects across NODDI metrics, which were grouped into three prominent patterns: cortical gray matter had predominantly higher free diffusion in older than younger adults, the hippocampus and amygdala had predominantly higher dispersion of diffusion and intracellular diffusion in older than younger adults, and the putamen and globus pallidus had lower dispersion of diffusion in older than younger adults.... https://escholarship.org/uc/item/2g16p0xp Thu, 11 Jun 2026 00:00:00 +0000 Greenman, Danielle Bennett, Ilana J https://orcid.org/0000-0002-5330-4679 https://escholarship.org/uc/item/1458p9sj <p>Healthy aging is accompanied by declines in the ability to learn associations between events, even when their relationship cannot be described. Previous functional magnetic resonance imaging (fMRI) studies have attributed these implicit associative learning (IAL) deficits to differential engagement of the hippocampus and basal ganglia in older relative to younger adults in early and late stages of the task, respectively. However, these task stages have been confounded with age group differences in learning performance that emerge later and to a lesser degree in older adults. To disentangle the effects of task stage from learning stage (i.e., when there is significant evidence of learning) on age group differences in the neural substrates of IAL, we acquired fMRI data while 28 younger (20.8 ± 2.3 years) and 22 older (73.6 ± 6.8 years) healthy adults completed the Triplets Learning Task, in which the location of two cues predicted the location of a target with high (HF) or low... https://escholarship.org/uc/item/1458p9sj Thu, 11 Jun 2026 00:00:00 +0000 Merenstein, Jenna Louise Petok, Jessica R Bennett, Ilana J https://orcid.org/0000-0002-5330-4679 https://escholarship.org/uc/item/1458d4j5 OBJECTIVE: Elevated kurtosis values have been observed in subcortical grey matter structures of patients with neurodegenerative diseases.

This has important implications for functional magnetic resonance imaging (fMRI) studies in aging as the presence of iron may influence both neuronal functioning as well as the measured fMRI (BOLD) signal, and these effects will vary across age groups and brain regions. To test this hypothesis, the current study examined the effect of iron on age group differences in task-related activity within each basal nuclei and the hippocampus. Twenty-eight younger and 22 older adults completed an associative learning task during fMRI acquisition. Iron content (QSM, R₂*) was estimated from a multi-echo gradient echo sequence. As previously reported, older adults learned significantly less than younger adults and age group differences in iron content were largest in the basal ganglia (putamen, caudate).... https://escholarship.org/uc/item/0bd5p26g Thu, 11 Jun 2026 00:00:00 +0000 Petok, Jessica R Merenstein, Jenna L Bennett, Ilana J https://orcid.org/0000-0002-5330-4679 https://escholarship.org/uc/item/3844m9kj <h4>Objective</h4>Neural tube defects (NTDs) are congenital anomalies caused by failure of neural tube closure during pregnancy and contribute to childhood morbidity and mortality.

In two studies, we investigated the link between cultural tightness and sociopolitical ideologies, beliefs, and personality traits within the United States and across 56 nations. We relied on two separate operationalizations of cultural tightness and aggregated self-reported sociopolitical ideologies, beliefs, and personality trait data from tens of thousands of geolocated internet respondents. Regression analyses suggest that more culturally tight U.S. states are less open, more conscientious, and higher in the need for certainty. Tighter states also more strongly endorse racial stereotyping, right-wing authoritarianism, and other system-justifying beliefs, but less weakly endorse egalitarianism. In addition, tighter nations are lower in extraversion and creativity. Taken together, we find that cultural tightness is a parsimonious predictor of regional... https://escholarship.org/uc/item/04d287c8 Thu, 21 May 2026 00:00:00 +0000 Wilson, Liz https://orcid.org/0000-0002-8068-980X Calanchini, Jimmy https://orcid.org/0000-0003-1959-143X https://escholarship.org/uc/item/41w6w2sc ObjectiveElevated kurtosis values have been observed in subcortical grey matter structures of patients with neurodegenerative diseases.

Some uncertainty is stressful and anxiety-provoking, some is comforting and protective, and some can even be pleasurable. This chapter addresses the various ways people manage uncertainty about the future. We first consider situations in which uncertainty is aversive, namely during stressful waiting periods. People regularly wait for feedback about their academic, professional, personal, and financial prospects, and most people find these waiting periods to be unpleasantly fraught with worry. Two theoretical models, the Uncertainty Navigation Model and the newer Emotion-Motivation-Obstruction (EMO) model, guide our coverage of aversive uncertainty and provide a roadmap to the subjective experiences, health consequences, and coping efforts such situation entail. We then turn to situations in which uncertainty is desirable. People regularly avoid information to which they have ready access, even when acquiring the information may benefit... https://escholarship.org/uc/item/01d2d9rm Thu, 7 May 2026 00:00:00 +0000 Sweeny, Kate Howell, Jennifer L https://escholarship.org/uc/item/5p33b3sp ObjectivesSuccess in life often requires patience.

The present research extends beyond individuals to investigate relationships among regional economic conditions, regional cognitive control, and intergroup bias. We aggregated 2.9 million US-based participants’ geolocated responses on the Black/White Implicit Association Test, then applied the Process Dissociation Procedure to estimate state-level cognitive control and racial evaluations across the years 2005 to 2019. Black populations’ cognitive control was weaker in states where Black residents faced more adverse economic conditions, but stronger in states where White residents faced more adverse economic conditions.

However, there is considerable diversity in Muslim youth: the vast majority immigrating from or have parents from various geographic regions: Southeast Asia, Middle East, North Africa, Europe, etc. A few studies have reported group differences with discrimination regarding the Muslim population. Given the different cultural contexts and intersections of identities, more research is needed to better understand how the diversity of Muslim youth in the U.S. may require different tailored interventions and prevention programs that foster positive learning outcomes. This review paper starts by reviewing research reporting factors impacting the well-being of Muslim youth.

Although research on the beneficial effects of flow is widespread, its multidisciplinary nature has precluded a clear consensus on their nature and strength. Results from a meta-analysis revealed a moderately strong, positive relationship between flow and well-being, consistent with our hypothesis. Features of the well-being measure moderated the association, such that eudaimonic measures showed a stronger association than did hedonic measures, and among hedonic measures, measures of cognitive well-being were more strongly associated with flow than affective measures. Measures of positive aspects of well-being were also more strongly associated with flow than measures of negative aspects. The association was surprisingly robust to features of the flow measure and activity, the design of the study, and characteristics of the sample.

When people face delays in achieving their goals, they may become impatient—and when they believe they are the cause of those delays, they may feel impatient with themselves. In this paper, we present a novel theoretical approach to understanding such moments of self‐impatience, adapted from the process model of patience . This approach positions self‐impatience as an emotional response to self‐caused delays that are unreasonable or inappropriate. To be patient with oneself, then, means to successfully regulate the feeling or consequences of self‐impatience. We outline our theoretical model of self‐patience, the process model of self‐patience , highlighting where it overlaps with and deviates from the original model. We then close with suggestions for future research that derive from our theoretical proposals. https://escholarship.org/uc/item/7d8064r8 Sun, 1 Mar 2026 00:00:00 +0000 Susoeff, Sophia Sweeny, Kate https://escholarship.org/uc/item/36n166qd Humans actively seek information to reduce uncertainty, providing insight on how our decisions causally affect the world. While we know that episodic memories can help support future goal-oriented behaviors, little is known about how hypothesis testing during exploration influences episodic memory. To investigate this question, we designed a hypothesis testing paradigm, in which participants figured out rules to unlock treasure chests. Using this paradigm, we characterized how hypothesis testing during exploration influenced memory for the contents of the treasure chests. We found that there was an inverted U-shaped relationship between decision uncertainty and memory, such that memory was best when decision uncertainty was moderate. An exploratory analysis also showed that surprising outcomes lead to lower memory confidence independent of accuracy. These findings support a model in which moderate decision uncertainty during hypothesis testing enhances incidental information encoding. https://escholarship.org/uc/item/36n166qd Mon, 16 Feb 2026 00:00:00 +0000 Shen, Xinxu Ballard, Ian C https://orcid.org/0000-0003-1814-3141 Smith, David V Murty, Vishnu P https://escholarship.org/uc/item/00w6986q Do goals, beliefs, and desires affect visual experience? This question has long been controversial in cognitive science. There exists extensive literature documenting motivational effects on perceptual reports, but these findings could reflect biases in what people report seeing rather than what they see. Here, we propose that examining the underlying neurocomputational processes can provide new perspectives on this longstanding debate. We review evidence suggesting that motivation biases both perception and action, but does so via distinct neural systems: amygdala and locus coeruleus (LC)-norepinephrine (NE) activity enhances sensory representations for desirable stimuli, while striatal dopamine biases action selection toward goal-congruent actions. The neurocomputational approach provides a framework to advance a mechanistic understanding of motivated seeing and how these biases are shaped by context. https://escholarship.org/uc/item/00w6986q Mon, 16 Feb 2026 00:00:00 +0000 Kim, Haena Ballard, Ian C https://orcid.org/0000-0003-1814-3141 Leong, Yuan Chang https://escholarship.org/uc/item/7wx8m5zv Between 1819 and the 1970s, the U.S. government forced Native American children to attend boarding schools with the explicit purpose of assimilating them into White American culture. In this article, we examined whether the cultural legacy of historical Native American boarding schools persists locally in the aggregated racial biases of modern-day residents. Using the data of 290,593 Project Implicit visitors, we found that counties where Native American boarding schools were located in the past show lower levels of modern-day racial prejudice against Native Americans and view Native Americans as more U.S. American/less foreign compared to counties without historical boarding schools. Our findings provide a nuanced perspective on the ways in which historical injustices can manifest in physical, social, and cultural environments. https://escholarship.org/uc/item/7wx8m5zv Tue, 3 Feb 2026 00:00:00 +0000 Primbs, Maximilian A Calanchini, Jimmy https://escholarship.org/uc/item/72x2w84s Abstract Patience has been a consistent source of interest and inspiration for generations of thinkers and writers. In this article, I delineate the tenets of a comprehensive framework for understanding patience, the process model of patience (Sweeny, Personality and Social Psychology Review , 2025, 29, 145), that positions impatience as a common and unpleasant emotion and patience as a targeted form of emotion regulation. I then outline potential applications of the model for consumer decisions, service experiences, and marketing contexts and close with practical recommendations to optimize consumer behavior in contexts where impatience is likely to arise. https://escholarship.org/uc/item/72x2w84s Thu, 29 Jan 2026 00:00:00 +0000 Sweeny, Kate https://escholarship.org/uc/item/2459x4rw This investigation tests whether people higher in trait patience navigate stressful waiting periods with greater emotional well-being and less maladaptive coping. In one exploratory study (N&nbsp;=&nbsp;799) and three conceptual replications (Ns&nbsp;=&nbsp;217, 410, 411), undergraduates completed a baseline survey assessing trait patience before entering a laboratory paradigm where they experienced uncertainty while awaiting feedback on their intelligence (Study 1), social skills (Study 2), health risk (Study 3), and attractiveness (Study 4). Participants completed measures of worry, positive and negative emotion, distraction, and suppression during the wait. Mini meta-analysis findings show that patient people worry less and feel less negative and more positive emotion when waiting for personally-relevant news, while avoiding the relatively maladaptive coping strategies of distraction and suppression, with the strongest associations emerging for positive emotion. https://escholarship.org/uc/item/2459x4rw Thu, 29 Jan 2026 00:00:00 +0000 Sweeny, Kate Schnitker, Sarah A https://escholarship.org/uc/item/995647pv Multinomial processing tree (MPT) models can provide novel insights into the cognitive processes underlying a wide variety of social cognitive judgments and behaviors. In previous research, MPT models have been used to disentangle the contributions of multiple latent processes to tasks configured to assess moral reasoning, processing fluency, decision-making, implicit biases, and social categorization, among many other topics. However, until recently, MPT models were limited in their application to categorical data. New methodological advances extend traditional MPT estimation methods by incorporating reaction time data, thereby expanding the breadth and depth of questions that can be investigated. This article provides a user-friendly step-by-step tutorial for response-time extended MPT methods with annotated code and data, using the Implicit Association Test as a working example. https://escholarship.org/uc/item/995647pv Thu, 6 Nov 2025 00:00:00 +0000 Wilson, Liz Hartmann, Raphael Klauer, Karl Christoph Laukenmann, Ruben Calanchini, Jimmy https://escholarship.org/uc/item/6ws9r0n7 Introduction to the Special Issue: Tutorials on Novel Methods and Analyses in Social Cognition, Part 1 https://escholarship.org/uc/item/6ws9r0n7 Thu, 6 Nov 2025 00:00:00 +0000 Calanchini, Jimmy Degner, Juliane Smith, Colin Tucker https://escholarship.org/uc/item/0dr5f1xn Introduction to the Special Issue: Tutorials on Novel Methods and Analyses in Social Cognition, Part 2 https://escholarship.org/uc/item/0dr5f1xn Thu, 6 Nov 2025 00:00:00 +0000 Smith, Colin Tucker Degner, Juliane Calanchini, Jimmy https://escholarship.org/uc/item/1qs144pr Purpose: Evidence on the impact of the coronavirus disease 2019 (COVID-19) pandemic on outcomes in patients with ovarian cancer patients is limited. We compared remission outcomes in patients with ovarian cancer before and during the pandemic. Patients and Methods: This retrospective cohort study included patients diagnosed with epithelial ovarian cancer between 01/01/2017 and 06/30/2021 at Kaiser Permanente Southern California. Pre and post pandemic periods were designated using March 4, 2020, as the cut-off. Stage I-IV patients who completed chemotherapy and/or surgery as first-line treatment were included. Data on remission outcomes (complete and clinical remission) were abstracted by manual chart reviews. Complete remission was defined as no evidence of disease; clinical remission included both complete and partial response to treatment. Modified Poisson regression was used to evaluate the association of pandemic and remission. Effect modification by race/ethnicity was evaluated.

Although MDMA is considered to enhance social connection to a greater extent than other stimulant drugs, few studies have compared MDMA to other stimulants. In addition, previous studies have focused on social positivity effects (e.g., increased trust) for specific in-lab interaction partners without considering more generalized social positivity effects (e.g., trust in one's community). AIMS: We tested the effects of MDMA on subjective ratings of well-being and global social connection, including feelings of trust toward one's community and society. The effects of MDMA were compared to a prototypic stimulant, methamphetamine (MA). METHODS: Across two studies, we examined differences in subjective well-being and global social well-being 90 minutes after a conversation on MDMA (study 1; <i>N</i> = 15; 100 mg) and after a conversation... https://escholarship.org/uc/item/0d96m72r Thu, 9 Oct 2025 00:00:00 +0000 Martinez, Ramona L Radošić, Nina Molla, Hanna de Wit, Harriet Lyubomirsky, Sonja https://orcid.org/0000-0003-0727-5595 https://escholarship.org/uc/item/4c37z9m3 A Multimethod Approach to Women's Experiences of Reproductive Health Screening https://escholarship.org/uc/item/4c37z9m3 Thu, 25 Sep 2025 00:00:00 +0000 Ghane, Arezou Sweeny, Kate Dunlop, William L https://escholarship.org/uc/item/05t1f0hm The Developing Belief Network is a global research collaborative studying religious development in diverse social-cultural settings, with a focus on the intersection of cognitive mechanisms and cultural beliefs and practices in early and middle childhood.

Consequently, teams with a higher (vs. lower) percentage of individuals from working-class contexts perform better. However, the COVID-19 pandemic has fundamentally changed the way teams work together, leading to a rise in asynchronous and remote teamwork. Here, we ask: Does the way people work together matter for the benefits documented in prior work? In this registered report, we examined meeting mode-that is, the extent to which teams work together synchronously and in-person (vs. asynchronously and remotely)-as an important boundary condition for the performance of people from working-class contexts in teams. We hypothesize and, in exploratory analyses, find preliminary support for the idea that the beneficial effects of working together for students from working-class contexts are diminished when teams work together primarily asynchronously and remotely.

We examine whether the manner in which economic inequality and policy are framed—in terms of either upper-socio-economic-class advantages or lower-socio-economic-class disadvantages—influences individuals’ reactions to inequality. Across five studies, framing redistributive policy (Study 1) as disadvantage-reducing (versus advantage-reducing) and economic inequality (Studies 2–5) as lower-class disadvantages (versus upper-class advantages or a control frame) enhances support for action to reduce inequality. Moreover, increased support is partly driven by perceptions that inequality is more unjust if framed as lower-class disadvantages. Using diverse methodologies (for example, social media engagement on Facebook) and nationally representative samples of self-reported upper-class and lower-class individuals, this work suggests that... https://escholarship.org/uc/item/2g93225f Wed, 10 Sep 2025 00:00:00 +0000 Dietze, Pia Craig, Maureen A https://escholarship.org/uc/item/2d48q2j0 The visual system takes advantage of redundancy in the world by extracting summary statistics, a phenomenon known as ensemble perception. Ensemble representations are formed for low-level features like orientation and size and high-level features such as facial identity and expression. Whereas recent research has shown that the visual system forms intact ensemble representations even when faces are partially occluded via solid bars, how ensemble perception is impacted with the addition of naturalistic objects such as face masks or sunglasses is largely unknown. To investigate this, we conducted a series of experiments using continuous report tasks in which faces (either varying in identity or expression) were partially occluded with a surgical mask or sunglasses and participants had to report the average face using a face wheel. We found evidence that participants could still accurately extract the average even when a significant portion of it was occluded with either face masks... https://escholarship.org/uc/item/2d48q2j0 Thu, 28 Aug 2025 00:00:00 +0000 Hendley, Hayden Schill Hassani, Natalia K Pallis Brady, Timothy F https://orcid.org/0000-0001-5924-5211 https://escholarship.org/uc/item/90n34580 <p>In daily life, we frequently feel for objects without vision using our sense called Haptics. Much of the research that has been done focused on single-handed searches with no agreed-upon conclusion on whether two hands are better than one. Here, we asked if there is a clear advantage, disadvantage, or no difference in simultaneous bimanual compared to sequential unimanual search. Participants felt for a unique target amongst uniformed distractors with their left hand only, right hand only, and with both hands simultaneously. Additionally, we asked how performance might vary when the distinguishing feature of the unique target was the same or different between the hands. Simultaneous bimanual search showed significantly more efficient search than the sequential unimanual search. Surprisingly, there was no appreciable difference between performance when searching for targets with the same and different features.

A total of 250 UC Riverside undergraduate participants viewed a series of pictures of the model’s silhouettes wearing Western-style wedding dresses and reported their perceptions (e.g., confident, original, shy, vain, fun) of the model in each picture. The wedding dresses varied in neckline (i.e., Sweetheart, V-Neck, Halter, High Neck) and silhouette (i.e., A-line, Mermaid, Fit and Flare, Ballgown). We found significant, reliable differences in how participants perceived the models as a function of dress silhouette and neckline. Specifically, participants perceived the models wearing the Fit and Flare silhouette to be especially confident, original, fun, and vain, but the models wearing the A-line silhouette to be the least confident, original, and fun. Furthermore, participants perceived the models wearing the V-neck neckline to be especially confident... https://escholarship.org/uc/item/7sd8m75t Mon, 11 Aug 2025 00:00:00 +0000 Hoang, Mindy Calanchini, Jimmy https://escholarship.org/uc/item/07f9w7fz <p>Community violence exposure increases risk for fear-based disorders, such as anxiety, potentially due to disrupted recall of extinguished fear, whereby stimuli previously associated with threat continue to produce a fear response long after they have been deemed safe.

This article investigates the extent to which the cultural legacy of racial hatred of the Klan has persisted over the years. We use data from large online databases, multiverse analyses, and spatial models to evaluate whether regions with more historical Klan activity show higher levels of modern-day racial bias, and more modern-day White Supremacist activity. We find that regions with more Ku Klux Klan activity in the 1920s show higher levels of modern White Supremacist activity but, unexpectedly, lower levels of modern implicit and explicit racial bias. We discuss the implications of these findings for models linking historical events with present-day attitudes and behavior, and for situational models of bias more broadly. https://escholarship.org/uc/item/9f4860mw Tue, 22 Jul 2025 00:00:00 +0000 Primbs, Maximilian A Wienk, Margaux NA Holland, Rob W Calanchini, Jimmy Bijlstra, Gijsbert https://escholarship.org/uc/item/99c2q87t A theoretical framework is offered to explain mood contagion processes in groups. Specifically, we describe and test a two-stage leader activation and member propagation (LAMP) model that starts with the activation of the contagion process by leaders (Stage 1), followed by the mutual propagation of the mood among members (Stage 2). Results from 102 self-managing groups provide support for the LAMP model. Group mood convergence was negatively related to attribute diversity (in extroversion and neuroticism) between the leader and group members (Stage 1) and among group members (Stage 2). In both stages, group members' susceptibility to emotional contagion and interpersonal attraction had positive main effects on group mood convergence, and moderated the relationship between attribute diversity and mood convergence in groups. The findings offer new insights into group mood convergence, as it unfolds over time. © 2013. https://escholarship.org/uc/item/99c2q87t Thu, 19 Jun 2025 00:00:00 +0000 Sy, Thomas Choi, Jin Nam https://escholarship.org/uc/item/8176p6vm Charismatic leadership: Eliciting and channeling follower emotions https://escholarship.org/uc/item/8176p6vm Thu, 19 Jun 2025 00:00:00 +0000 Sy, Thomas Horton, Calen Riggio, Ronald https://escholarship.org/uc/item/7hg2w614 Over four decades, research has demonstrated Pygmalion and Galatea effects (positive expectations leading to high performance) across various settings. In contrast, research on the parallel notion of Golem effects (negative expectations leading to low performance) has been largely overlooked. This study is the first to examine the relationship between group-level Implicit Followership Theories (GIFTs) and naturally occurring Golem effects. Integrating the literature on Implicit Followership Theories, self-fulfilling prophecies, and social identity, we propose that negative GIFTs can serve as proxies of expectations for followers that trigger Golem effects in workgroups. Data from 202 followers and 101 leaders provide support for our hypothesized multi-level model, revealing a top-down relationship between negative GIFTs and follower performance through their self-efficacy and effort.

We investigate the specific emotional content and structure of ITLEs. Five studies involving 1286 participants provide evidence for content, convergent, discriminant, criterion, and incremental validity, and internal consistency of the ITLEs instrument. ITLEs are represented by a first‐order structure (Cheer, Calm, Pride, Anger, Fear, and Remorse), and a second‐order structure (Positive and Negative ITLEs). Results revealed that female leaders elicited lower ratings on the Anger, Fear, and Remorse prototypes and higher ratings on the Cheer (but not Pride and Calm) prototype. Moreover, the relationship between ITLEs prototypes and leadership perceptions were moderated by management level, such that the relationship was significant only for high level leaders but not low level leaders.

Using parental report data on child word production from the MacArthur-Bates Communicative Development Inventory, we found evidence that while children produced words referring to imperceptible referents before age 2, such words were less likely to be produced relative to words with perceptible referents. For instance, blind (vs. sighted) children said fewer highly visual words like "blue" or "see"; deaf signing (vs. hearing) children produced fewer auditory signs like hear.

The problem seems intractable if a large number of successful and unsuccessful trials are infeasible. We offer a solution based on estimates of task-specific variability pooled across the sample. Using a dataset of adult performance in throwing and walking tasks, we show that mischaracterizing the slope leads to unacceptably large errors in estimates of performance levels that undermine analyses of risk perception. We introduce a "pooled-slope" solution that approximates estimates of individual variability in performance and outperforms arbitrary assumptions about performance variability within and across tasks. We discuss the advantages of objectively measuring performance based on the rate of successful attempts-modeled via psychometric functions-for improving comparisons of risk across participants, tasks, and studies. https://escholarship.org/uc/item/96f8d10h Wed, 2 Apr 2025 00:00:00 +0000 Franchak, John M https://orcid.org/0000-0002-0751-2864 Hospodar, Christina M Adolph, Karen E https://escholarship.org/uc/item/85g8797q MDMA is a recreational drug commonly used to enhance euphoria, but it is also used in non-party settings with self-insight or social connection intentions.

This hypothesis was tested in four studies (total N = 2,920), using both self-reported and objective bank-reported spending data. In our correlational analyses, hedonic spending variety was uniquely associated with well-being, even after controlling for total hedonic spending and other financial variables.

Since this first detection, research has indicated that people contracting the virus may suffer neurological and mental disorders and deficits, in addition to the respiratory and other organ challenges caused by COVID-19. Specifically, early evidence suggests that COVID-19 has both mild (e.g., loss of smell (anosmia), loss of taste (ageusia), latent blinks (heterophila), headaches, dizziness, confusion) and more severe outcomes (e.g., cognitive impairments, seizures, delirium, psychosis, strokes). Longer-term neurological challenges or damage may also occur. This knowledge should inform clinical guidelines, assessment, and public health planning while more systematic research using biological, clinical, and longitudinal methods provides further insights. https://escholarship.org/uc/item/1mn7b2gw Thu, 27 Mar 2025 00:00:00 +0000 Aknin, Lara B De Neve, Jan Emmanuel Dunn, Elizabeth W Fancourt, Daisy E Goldberg, Elkhonon Helliwell, John F Jones, Sarah P Karam, Elie Layard, Richard Lyubomirsky, Sonja https://orcid.org/0000-0003-0727-5595 Rzepa, Andrew Saxena, Shekhar Thornton, Emily M VanderWeele, Tyler J Whillans, Ashley V Zaki, Jamil Caman, OzgeKaradag Amor, Yanis Ben https://escholarship.org/uc/item/6wh3h007 In our everyday lives, we must remember important information, especially if there are consequences for forgetting. In this review, I discuss recent work on responsible remembering: the strategic and effortful prioritization of important information with consequences for forgetting. Thus far, research regarding responsible remembering has revealed several key factors and mechanisms that work together to enhance memory for important information that will continue to be refined: the identification and selection of what to remember (metacognitive reflectivity), the forgetting of less important information to facilitate memory for items that do need to be remembered (responsible forgetting), the functional prioritization of attention at the expense of competing factors (responsible attention), and the selective recall of important information via efficient retrieval strategies (responsible retrieval). Together, these functions form a cohesive system that aims to selectively prioritize,... https://escholarship.org/uc/item/6wh3h007 Mon, 24 Mar 2025 00:00:00 +0000 Murphy, Dillon https://escholarship.org/uc/item/62p4s4z9 Prosocial and health protective behaviors are critical to contain the COVID-19 pandemic, yet adolescents have been difficult to engage. Attachment security promotes adolescents' capacities to navigate stress, and influences prosocial and health behaviors. Drawing on a diverse sample of 202 adolescents (48% female; 47.5% Latinx) this study evaluated relations among attachment, mental health, and prosocial and health protective responses to the COVID-19 pandemic. Attachment security (age 12) predicted adolescents' (age 15) COVID-19 prosocial (f² &nbsp;=&nbsp;.201) and health protective behaviors (f² &nbsp;=&nbsp;.274) during the pandemic via smaller-than-expected increases in mental health symptoms above pre-pandemic levels (age 14). Findings highlight the importance of attachment for supporting adolescents' mental health responses to life stressors and promoting prosocial and health protective behaviors. https://escholarship.org/uc/item/62p4s4z9 Tue, 18 Mar 2025 00:00:00 +0000 Coulombe, Brianne R Yates, Tuppett M https://orcid.org/0000-0002-0907-8520 https://escholarship.org/uc/item/619427h5 This investigation evaluated a theoretically specified model of associations among mothers' history of child sexual abuse (CSA), a helpless state of mind (SOM) with regard to the mother-child relationship, and increased behavior problems in the next generation. Moreover, we evaluated the moderating influence of child gender on predicted relations between mothers' CSA severity and helpless SOM (i.e., moderated mediation). Participants were 225 biological mother-preschooler dyads (48% female; 46.4% Latinx) drawn from an ongoing, longitudinal study of representation and regulation in child development. Mothers' history of CSA was assessed when their children were 4 years old and emerged as a prominent risk factor in this diverse, high-risk community sample with 40% of mothers reporting contact-based sexual abuse prior to age 18.

In Experiment 1, we created a situation where there was a buildup of interference such that participants could recall words from any studied list to earn points. However, to increase participants' motivation to combat interference, we told participants that if they recalled words from previously studied lists, those words would be worth double the original point value of the word. In Experiment 2, to examine age-related differences in the absence of any interference, participants studied and were tested on the same set of words throughout several study-test cycles.

Controlling for youth ethnicity and race, family income-to-needs, and prior levels of maternal psychological control at age 10, structural equation models showed that maternal problems (i.e., anxiety, alcohol dependence, caregiving helplessness) predicted increases and youth externalizing problems (e.g., attention problems, rule-breaking) predicted decreases in maternal reports of psychological control.

Being selective about which information we consolidate into our long-term memory becomes even more important when there is insufficient time to encode and retrieve information. We investigated whether older and younger adults differ in how time constraints, whether at encoding (Experiment 1) or retrieval (Experiment 2), affect their ability to be selective when remembering important information that they need to recall later. In Experiment 1, we found that younger and older adults exhibited similar selectivity, and the participants remained selective when rushed at encoding. In Experiment 2, older adults maintained their selectivity when given insufficient time at retrieval, but younger adults' selectivity was increased when given limited recall time.

Although related to maladaptive outcomes in studies of adult children, FMSS EOI evidences varied relations with behavior problems in studies with young children. These mixed findings may indicate that certain FMSS EOI criteria reflect inappropriate and excessive involvement with adult children, but do not indicate maladaptive processes when parenting younger children. Thus, this study evaluated relations of each FMSS EOI criterion with changes in child behavior problems from preschool to first grade in a community sample of 223 child–mother dyads (47.98% female; Wave 1 M(age) 49.08 months; 56.50% Hispanic/Latina).

To further understand participants' experiences in extraverted behavior interventions, we analyzed free‐response data from a study in which undergraduate participants generated ideas on desirable outcomes, anticipated obstacles, and prospective plans in their efforts to act more sociable. Additionally, to understand the potential relationship between components of person‐activity fit (how natural, enjoyable, and meaningful a person finds an intervention activity like acting more extraverted), we conducted exploratory correlational analyses between the components of fit, personality traits, desire to change extraversion, and the endorsement of outcomes, challenges, and plans identified from our thematic... https://escholarship.org/uc/item/11s2m4st Thu, 13 Mar 2025 00:00:00 +0000 Martinez, Ramona L Regan, Annie Gollwitzer, Peter M Oettingen, Gabriele Lyubomirsky, Sonja https://orcid.org/0000-0003-0727-5595 https://escholarship.org/uc/item/3nq3v7bc Millions of people move within the U.S. each year. We propose that people function as proxies for their locations, bringing the culture of their previous residence to their new homes. As a result, migration might systematically influence regional biases across geographic units over time. Using county-to-county migration data from the U.S. census and county-level racial attitude estimates from Project Implicit, the present research examined the impact of people relocating from one U.S. county to another on racial attitudes in their new county. Consistent with our prediction, the bias brought by the migrants positively predicts county-level racial bias after migration, even after controlling for county-level racial bias before migration. This finding remains robust across various sample inclusion criteria and spans three time periods (2006–2010, 2011–2015, and 2016–2020).

Prior work suggests altered intertemporal decision-making in this disorder, with more farsighted decisions—i.e. reduced delay discounting—in patients with acute anorexia nervosa. Future-oriented cognition, such as frequent prospective future thinking in daily life, promotes farsighted decision making. However, whether temporal orientation is altered in anorexia nervosa, potentially contributing to reduced delay discounting in this population, remains unclear. We measured delay discounting behavior, anorexia nervosa symptomatology, and temporal orientation in a large sample of never-diagnosed individuals. We found that higher anorexia nervosa symptomatology was associated with reduced delay discounting. Anorexia nervosa symptoms were also correlated with increased future-oriented cognition.

Impulsivity is a hallmark of human decision making with well documented health and financial ramifications. Numerous contextual changes and framing manipulations powerfully influence impulsivity. One of the most robust such phenomenon is the finding that people are more patient as the values of choice options are increased. This magnitude effect has been related to cognitive control mechanisms in the dorsal lateral prefrontal cortex (dlPFC). We used repetitive transcranial magnetic stimulation (rTMS) to transiently disrupt dlPFC neural activity. This manipulation dramatically reduced the magnitude effect, establishing causal evidence that the magnitude effect depends on dlPFC. https://escholarship.org/uc/item/2229d1t1 Wed, 29 Jan 2025 00:00:00 +0000 Ballard, Ian C https://orcid.org/0000-0003-1814-3141 Aydogan, Gökhan Kim, Bokyung McClure, Samuel M https://escholarship.org/uc/item/3px397tr Recent work has identified a critical role for the hippocampus in reward-sensitive behaviors, including motivated memory, reinforcement learning, and decision-making.

Reinforcement learning models capture many behavioral and neural effects but do not explain recent findings showing that structure in the environment influences learning. In parallel, Bayesian cognitive models predict how humans learn structured knowledge but do not have a clear neurobiological implementation. We propose an integration of these two model classes in which structured knowledge learned via approximate Bayesian inference acts as a source of selective attention. In turn, selective attention biases reinforcement learning towards relevant dimensions of the environment. An understanding of structure learning will help to resolve the fundamental challenge in decision science: explaining why people make the decisions they do. https://escholarship.org/uc/item/41d3x1sf Fri, 24 Jan 2025 00:00:00 +0000 Radulescu, Angela Niv, Yael Ballard, Ian https://escholarship.org/uc/item/3zk778bx Animals rely on learned associations to make decisions. Associations can be based on relationships between object features (e.g., the three leaflets of poison ivy leaves) and outcomes (e.g., rash). More often, outcomes are linked to multidimensional states (e.g., poison ivy is green in summer but red in spring). Feature-based reinforcement learning fails when the values of individual features depend on the other features present. One solution is to assign value to multi-featural conjunctive representations. Here, we test if the hippocampus forms separable conjunctive representations that enables the learning of response contingencies for stimuli of the form: AB+, B-, AC-, C+. Pattern analyses on functional MRI data show the hippocampus forms conjunctive representations that are dissociable from feature components and that these representations, along with those of cortex, influence striatal prediction errors.

Many researchers are interested in relating parameters of reinforcement learning models to neural measures, psychological variables or experimental manipulations. We demonstrate that parameter identification is difficult because a range of parameter values provide approximately equal quality fits to data. This identification problem has a large impact on power: we show that a researcher who wants to detect a medium sized correlation (r = .3) with 80% power between a variable and learning rate must collect 60% more subjects than specified by a typical power analysis in order to account for the noise introduced by model fitting.

Midbrain neurons have fast and slow signaling components, and specific afferent systems, such as the hippocampus (HPC) and prefrontal cortex (PFC), have been demonstrated to drive these components in anesthetized animals. Whether these interactions exist during behavior, however, is unknown. To address this question, we developed a novel analysis of human functional magnetic resonance imaging data that fits models of network excitation and inhibition on ventral tegmental area (VTA) activation. We show that specific afferent systems predict distinct temporal components of midbrain VTA signal. We found that PFC, but not HPC, positively predicted transient, event-evoked VTA activation. In contrast, HPC, but not PFC, positively predicted slow shifts in VTA baseline variability. Thus, unique functional contributions of afferent systems to VTA physiology are detectable at the network... https://escholarship.org/uc/item/1pj2g4tp Fri, 24 Jan 2025 00:00:00 +0000 Murty, Vishnu Ballard, Ian Adcock, R https://escholarship.org/uc/item/6tw141rf Visual perceptual learning (VPL), the training-induced improvement in visual tasks, has long been considered the product of neural plasticity at early and local stages of signal processing. However, recent evidence suggests that multiple networks and mechanisms, including stimulus- and task-specific plasticity, concur in generating VPL. Accordingly, early models of VPL, which characterized learning as being local and mostly involving early sensory areas, such as V1, have been updated to embrace these newfound complexities, acknowledging the involvement on parietal (i.e. intra-parietal sulcus) and frontal (i.e. dorsolateral prefrontal cortex) areas, in aspects concerning decision-making, feedback integration and task structure.

The dichotomy between habitual action selection and flexible goal-directed behavior has recently been challenged by findings showing that rewards bias both action and goal selection. Here, we test whether reward reinforcement can give rise to habitual goal selection much as it gives rise to habitual action selection.

Our data revealed diverse spike waveforms among neurons in the LC region, including a considerable fraction of narrow-spiking units. While all wide-spiking units possessed the regular waveform polarity (negative-positive deflection), the narrow units can be further divided based on opposing waveform polarities. Under anesthesia, wide units emitted action potential at a higher rate than the narrow units. Under wakefulness, only one subtype of narrow units exhibited fast-spiking phenotype.

Recent studies suggest that combining visual perceptual learning (VPL) training with concomitant transcranial electric stimulation (tES) leads to learning rate and generalization effects larger than each technique used individually. Both VPL and tES have been used to induce neural plasticity in brain regions involved in visual perception, leading to long-lasting visual function improvements.

This investigation provides an initial test of the tenets of this new theoretical model, which positions impatience as a discrete emotion and patience as a targeted form of emotion regulation. In three studies with diverse samples (<i>N</i> = 1,401; data collected 2022-2023), participants responded to hypothetical scenarios designed to tap into familiar experiences of impatience. Regarding impatience, findings support our claim that impatience arises in response to the perception that a delay is unreasonable or unfair, and situational and intrapersonal characteristics emerged as predictors of impatience. Regarding patience, findings were consistent with the conceptualization of patience as driven more by intrapersonal than situational factors and revealed a set of individual differences that predicted patience. This investigation lends support to the process model of patience as... https://escholarship.org/uc/item/24w7d7q2 Thu, 21 Nov 2024 00:00:00 +0000 Sweeny, Kate Hawes, Jason Karaman, Olivia T https://escholarship.org/uc/item/2z21m9nc People are often presented with large amounts of information to remember, and in many cases, the font size of information may be indicative of its importance (such as headlines or warnings). In the present study, we examined how learners perceive the importance of information in different font sizes and how beliefs about font size influence selective memory. In Experiment 1, participants were presented with to-be-remembered words that were either unrelated or related to a goal (e.g., items for a camping trip) in either small or large font. Participants rated words in large font as more important to remember than words in small font when the words in a list were unrelated but not when the words were schematically related to a goal. In Experiments 2&nbsp;and 3, we were interested in how learners’ belief that font size is indicative of importance translates to their ability to selectively encode and recall valuable information. Specifically, we presented participants with words in... https://escholarship.org/uc/item/2z21m9nc Mon, 11 Nov 2024 00:00:00 +0000 Murphy, Dillon H https://orcid.org/0000-0002-5604-3494 Rhodes, Matthew G Castel, Alan D https://orcid.org/0000-0003-1965-8227 https://escholarship.org/uc/item/7tg7g8r6 BACKGROUND: Childhood disadvantage is a prominent risk factor for cognitive and brain aging. Childhood disadvantage is associated with poorer episodic memory in late midlife and functional and structural brain abnormalities in the default mode network (DMN). Although age-related changes in DMN are associated with episodic memory declines in older adults, it remains unclear if childhood disadvantage has an enduring impact on this later-life brain-cognition relationship earlier in the aging process. Here, within the DMN, we examined whether its cortical microstructural integrity-an early marker of structural vulnerability that increases the risk for future cognitive decline and neurodegeneration-is associated with episodic memory in adults at ages 56-66, and whether childhood disadvantage moderates this association. METHODS: Cortical mean diffusivity (MD) obtained from diffusion magnetic resonance imaging was used to measure microstructural integrity in 350 community-dwelling men.... https://escholarship.org/uc/item/7tg7g8r6 Sat, 9 Nov 2024 00:00:00 +0000 Tang, Rongxiang Elman, Jeremy A https://orcid.org/0000-0002-5840-1769 Dale, Anders M Dorros, Stephen M Eyler, Lisa T https://orcid.org/0000-0002-7783-8798 Fennema-Notestine, Christine Gustavson, Daniel E Hagler, Donald J Lyons, Michael J Panizzon, Matthew S https://orcid.org/0000-0002-6449-2097 Puckett, Olivia K Reynolds, Chandra A https://orcid.org/0000-0001-6502-7173 Franz, Carol E Kremen, William S https://escholarship.org/uc/item/33q494t4 Eye tracking provides direct, temporally and spatially sensitive measures of eye gaze. It can capture visual attention patterns from infancy through adulthood. However, commonly used screen-based eye tracking (SET) paradigms are limited in their depiction of how individuals process information as they interact with the environment in “real life”. Mobile eye tracking (MET) records participant-perspective gaze in the context of active behavior. Recent technological developments in MET hardware enable researchers to capture egocentric vision as early as infancy and across the lifespan. However, challenges remain in MET data collection, processing, and analysis. The present paper aims to provide an introduction and practical guide to starting researchers in the field to facilitate the use of MET in psychological research with a wide range of age groups. First, we provide a general introduction to MET. Next, we briefly review MET studies in adults and children that provide new insights... https://escholarship.org/uc/item/33q494t4 Sat, 9 Nov 2024 00:00:00 +0000 Fu, Xiaoxue Franchak, John M https://orcid.org/0000-0002-0751-2864 MacNeill, Leigha A Gunther, Kelley E Borjon, Jeremy I Yurkovic-Harding, Julia Harding, Samuel Bradshaw, Jessica Pérez-Edgar, Koraly E https://escholarship.org/uc/item/0w441389 Self-control plays a pivotal role in pursuing long-term goals related to health and financial well-being. While ample evidence suggests that humans are prone to occasional self-control lapses, little is known about how changes in emotional and attentional states affect the ability to maintain self-control. In two studies (N1 = 109 and N2 = 90), we used emotion recognition software to decode participants’ facial expressions while manipulating their attentional and emotional states during a Psychomotor Vigilance Task (PVT) before exerting self-control in a subsequent task. Our findings reveal dissociable roles of attention and valence in maintaining self-control, depending on the distinct demands of the task. Specifically, performance in a subsequent cognitive task was predominantly associated with changes in attentional states during the PVT rather than valence. Conversely, preferences in a subsequent social task were associated with changes in valence states during the PVT, while... https://escholarship.org/uc/item/0w441389 Sat, 9 Nov 2024 00:00:00 +0000 Aydogan, Gökhan Kretschmer, Janek Brewer, Gene McClure, Samuel M https://escholarship.org/uc/item/7mg0q7nz Both scientists and laypeople have become increasingly concerned about smartphones, especially their associated digital media (e.g., email, news, gaming, and dating apps) and social media (e.g., Facebook, Instagram, Snapchat). Recent correlational research links substantial declines in Gen Z well-being to digital and social media use, yet other work suggests the effects are small and unnoteworthy. To help further disentangle correlation from causation, we conducted a preregistered 8-day experimental deprivation study with Gen Z individuals (N = 338). Participants were randomly assigned to one of four conditions: (1) restrict digital media (i.e., smartphone) use, (2) restrict social media use, (3) restrict water use (active control), or (4) restrict nothing (measurement-only control). Relative to controls, participants restricting digital media reported a variety of benefits, including higher life satisfaction, mindfulness, autonomy, competence, and self-esteem, and reduced loneliness... https://escholarship.org/uc/item/7mg0q7nz Thu, 7 Nov 2024 00:00:00 +0000 Walsh, Lisa C https://orcid.org/0000-0002-9689-4824 Regan, Annie Okabe-Miyamoto, Karynna Lyubomirsky, Sonja https://orcid.org/0000-0003-0727-5595 https://escholarship.org/uc/item/7x86n5r2 Researchers have become increasingly aware that data-analysis decisions affect results. Here, we examine this issue systematically for multinomial processing tree (MPT) models, a popular class of cognitive models for categorical data. Specifically, we examine the robustness of MPT model parameter estimates that arise from two important decisions: the level of data aggregation (complete-pooling, no-pooling, or partial-pooling) and the statistical framework (frequentist or Bayesian). These decisions span a <i>multiverse</i> of estimation methods. We synthesized the data from 13,956 participants (164 published data sets) with a meta-analytic strategy and analyzed the <i>magnitude of divergence</i> between estimation methods for the parameters of nine popular MPT models in psychology (e.g., process-dissociation, source monitoring). We further examined moderators as potential <i>sources of divergence</i>. We found that the absolute divergence between estimation methods was small on... https://escholarship.org/uc/item/7x86n5r2 Thu, 10 Oct 2024 00:00:00 +0000 Singmann, Henrik Heck, Daniel W Barth, Marius Erdfelder, Edgar Arnold, Nina R Aust, Frederik Calanchini, Jimmy Gümüsdagli, Fabian E Horn, Sebastian S Kellen, David Klauer, Karl C Matzke, Dora Meissner, Franziska Michalkiewicz, Martha Schaper, Marie Luisa Stahl, Christoph Kuhlmann, Beatrice G Groß, Julia https://escholarship.org/uc/item/7x24t480 Some people use health care services more than others. Identifying factors associated with health care use has the potential to improve the effectiveness, efficiency, and equity of health care. In line with the Andersen behavioral model of health care utilization and initial empirical findings, personality traits may be key predisposing factors associated with health care use. Across 15 samples, the present study examined cross-sectional and prospective associations between Big Five personality traits and the likelihood of dental visits, general medical practitioner visits, and hospitalizations. Using coordinated data analysis, we estimated models within each of 15 samples individually (sample Ns ranged from 516 to 305,762), and then calculated weighted mean effect sizes using random-effects meta-analysis across samples (total <i>N</i> = 358,803).

However, real-world visual exploration entails active movements of both eyes and head to bring relevant areas in view. Thus, relatively little is known about how infants coordinate their eyes and heads to structure their visual experiences. Infants were tested every 3 months from 9 to 24 months while they played with their caregiver and three toys while sitting in a highchair at a table. Infants wore a head-mounted eye tracker that measured eye movement toward each of the visual targets (caregiver's face and toys) and how targets were oriented within the head-centered field of view (FOV). With age, infants increasingly aligned novel toys in the center of their head-centered FOV at the expense of their caregiver's face. Both faces and toys were better centered in view during longer looking events, suggesting that infants of all ages aligned... https://escholarship.org/uc/item/18c5m63s Thu, 12 Sep 2024 00:00:00 +0000 Franchak, John M https://orcid.org/0000-0002-0751-2864 Smith, Linda Yu, Chen https://escholarship.org/uc/item/31t923tr Vasoactive intestinal peptide (VIP) interneurons in sensory cortex modulate sensory responses based on global exploratory behavior and arousal state, but their function during non-exploratory, goal-directed behavior is not well understood. In particular, whether VIP cells are activated by sensory cues, reward-seeking actions, or directly by reinforcement is unclear. We trained mice on a Go/NoGo whisker touch detection task that included a delay period and other features designed to separate sensory-evoked, action-related, and reward-related neural activity. Mice had to lick in response to a whisker stimulus to receive a variable-sized reward. Using two-photon calcium imaging, we measured ΔF/F responses of L2/3 VIP neurons in whisker somatosensory cortex (S1) during behavior. In both expert and novice mice, VIP cells were strongly activated by whisker stimuli and goal-directed actions (licking), but not by reinforcement. VIP cells showed somatotopic whisker tuning that was spatially... https://escholarship.org/uc/item/31t923tr Wed, 4 Sep 2024 00:00:00 +0000 Ramamurthy, Deepa L Chen, Andrew Zhou, Jiayu Park, Chanbin Huang, Patrick C Bharghavan, Priyanka Krishna, Gayathri Liu, Jinjian Casale, Kayla Feldman, Daniel E https://escholarship.org/uc/item/5wb1576h Correction for O’Donnell et al., Empirical audit and review and an assessment of evidentiary value in research on the psychological consequences of scarcity https://escholarship.org/uc/item/5wb1576h Wed, 28 Aug 2024 00:00:00 +0000 O'Donnell, Michael Dev, Amelia S Antonoplis, Stephen Baum, Stephen M Benedetti, Arianna H Brown, N Derek Carrillo, Belinda Choi, Andrew L Connor, Paul Donnelly, Kristin Ellwood-Lowe, Monica E Foushee, Ruthe Jansen, Rachel Jarvis, Shoshana N Lundell-Creagh, Ryan Ocampo, Joseph M Okafor, Gold N Azad, Zahra Rahmani Rosenblum, Michael Schatz, Derek Stein, Daniel H Wang, Yilu Moore, Don A https://orcid.org/0000-0002-6537-9598 Nelson, Leif D https://escholarship.org/uc/item/8j826439 Waiting for important news is uniquely anxiety provoking, and expectations for one's outcome fluctuate throughout the wait. Emotional volatility is typically associated with negative outcomes, but little is known about volatility in expectations. In Study 1, law graduates (<i>N</i> = 248) estimated their chances of passing the bar exam every 2 weeks during the wait for results. Greater volatility in expectations, operationalized as the frequency with which outcome expectations changed during the wait, was associated with greater worry and more negative emotionality throughout the wait. Study 2 partially replicated these findings in a sample of Trump and Biden supporters (<i>N</i> = 444) awaiting the result of the 2020 presidential election. Study 2 also demonstrated a causal link between constrained (vs. volatile) expectations and worry. Our findings have implications for how best to manage one's expectations while awaiting important news, with the goal of minimizing worry and... https://escholarship.org/uc/item/8j826439 Wed, 21 Aug 2024 00:00:00 +0000 Wilson, Melissa Sweeny, Kate https://escholarship.org/uc/item/1fb8v9h5 Academic AbstractPatience has been of great interest to religious scholars, philosophers, and psychological scientists. Their efforts have produced numerous insights but no cohesive theoretical approach to understanding the broad set of experiences people label as patience. I propose a novel view of patience, one that departs from but ties together existing approaches. Grounded in theories of emotion and emotion regulation, I propose impatience as a discrete emotion triggered by an objectionable delay of some sort, and patience (as a state or process rather than a virtue) as a form of emotion regulation that targets the subjective experience and outward expression of impatience. I propose a number of predictors and consequences of patience and impatience and provide initial evidence for many of the theory's tenets. This theoretical approach, the <i>process model of patience</i>, reveals coherence across varied fields and methodologies and generates novel, testable, and timely... https://escholarship.org/uc/item/1fb8v9h5 Wed, 21 Aug 2024 00:00:00 +0000 Sweeny, Kate https://escholarship.org/uc/item/85d437sc OBJECTIVE: Social deficits are already exhibited by people at risk for schizophrenia-spectrum disorders. Technological advances have made passive detection of social deficits possible at granular levels. METHOD: In this real-world study, we tested if schizotypy status (high/low) predicted two types of social behavior: (1) being around other people; and (2) actively socializing with others. We also examined if schizotypy influences relationships between social behavior and affect using subjective and objective instruments. RESULTS: Our findings revealed that socializing with others was significantly decreased in the high schizotypy group. Positive affect increased in social situations and predicted later social behavior in those low, but not high, in schizotypy. CONCLUSION: Decreased social behavior in schizotypy may be explained, in part, by these individuals being less incentivized than their peers to pursue social situations. Future studies should test this explanation in larger... https://escholarship.org/uc/item/85d437sc Thu, 8 Aug 2024 00:00:00 +0000 Minor, Kyle S Hardin, Kathryn L Beaudette, Danielle M Waters, Lesley C White, Anna L Gonzenbach, Virgilio Robbins, Megan L https://orcid.org/0000-0001-7114-9214 https://escholarship.org/uc/item/0z9622z1 The present study examined people’s perceptions of others as a function of fashion choices,specifically Western wedding dresses.

We found significant, reliabledifferences in how participants perceived the models as a function of dress silhouette andneckline. Specifically, participants perceived the models wearing the Fit and Flare silhouette tobe especially confident, original, fun, and vain, but the models wearing the A-line silhouette tobe the least confident, original, and fun.
