Are There Sex Differences in How Social Cohesion and Loneliness Relate To Cognitive Decline in Latinos
(Oxford University Press, 2025) Muniz-Terrera, Graciela; Marroig, Alejandra; Gutierrez, Angela; Tobin, Courtney Thomas; Sevi, Baris
Latinos are the largest minoritized population in the US, and therefore, understanding cognitive decline in this population is paramount. Previous literature has identified exogenous factors, such as social cohesion and endogenous factors, such as loneliness, as associated with cognitive decline in older men and women. To improve our understanding of the role of social cohesion and loneliness on cognitive decline in Latino older adults, we fitted independent linear mixed effects models to cognitive scores from men and women aged 50 and older (n = 2,321) who participated in the Health and Retirement Study (2006 - 2016), accounting for both, social cohesion and loneliness. Models were also adjusted for sociodemographic factors. In men and women, social cohesion was positively associated with baseline cognitive function (p < 0.001), while loneliness was negatively associated with baseline cognitive function (p < 0.001). The effect size of loneliness on baseline cognition in men was 3-fold the effect of social cohesion in men, while in women, it was 2-fold. However, none of these factors were significantly associated with cognitive trajectories over time. These findings highlight the importance of the role of exogenous and endogenous domains of the exposome in cognitive function among Latino adults. Health promotion initiatives should focus on implementing culturally appropriate strategies that enhance social cohesion within neighborhoods and help reduce feelings of loneliness.
Mice Extrapolate Temporal Information Based on Previously Learned Spatiotemporal Mappings: An Asymmetrical Case
(Springer, 2026) Gur, Ezgi; Duyan, Yalcin A.; Toptas, Pinar; Balci, Fuat
One of the computational affordances of isomorphic magnitude representations is the extrapolation of temporal information based on previously experienced spatiotemporal pairings. We initially trained mice on the association of two intervals (10 s and 30 s) with two hoppers (H2 and H4, counterbalanced) in a five-choice nose-poke box with the following setup. One of the three novel hoppers (H1) neighbored H2 only, the other novel hopper (H5) neighbored H4 only, and the third novel hopper (H3) neighbored H2 and H4 (H1Novel -> H2Trained -> H3Novel -> H4Trained -> H5Novel). During test trials, one of the five hoppers was illuminated. We estimated the trial time at which the anticipatory response rate was maximal (peak time) separately for each hopper. Mice extrapolated temporal information only in a forward fashion; the peak time for H5 was longer than that for H4. Mice did not extrapolate temporal information backward; the timed response curves in H1 and H3 were closely similar to those in H2. Thus, our findings suggest that mice can extrapolate temporal information, but also indicate that the computations underlying this process are directionally constrained. We discuss the possible reasons behind asymmetrical extrapolation.
Big-5 Personality Traits as Predictors of Allostatic Load in Latino Americans: A Longitudinal Study
(Oxford Univ Press Inc, 2025) Sevi, Baris; Supiyev, Adil; Gutierrez, Angela; Graham, Eileen K.; Mroczek, Daniel K.; Muniz-Terrera, Graciela
Objectives Allostatic load (AL) refers to the measure of cumulative wear and tear resulting from chronic stress and life events. AL presents adverse consequences for a diverse range of health conditions, and Latino populations show a high risk for elevated AL. This study aimed to test the Big-5 personality traits as possible predictors of AL in Latinos.Methods Using data from the Health and Retirement Study, we examined the Big-5 and AL connection through three time points in 8 years (Time 1 = 2006/2008; Time 2 = 2010/2012; Time 3 = 2014/2016). Only self-identified Latinos were included in the analysis sample (N = 319). Big-5 and demographics were obtained at baseline, and AL scores were computed for each time point.Results First, separate longitudinal linear mixed-effect models examined the effects of each Big-5 personality trait on AL change over time, then a fully adjusted longitudinal linear mixed-effect model was tested entering the Big-5 personality traits simultaneously. All models controlled for sociodemographic factors. Conscientiousness emerged as the only consistent significant predictor, for the separate and the simultaneous models. In baseline associations, higher conscientiousness was associated with lower AL. For predicting change in AL over time, none of the personality traits had significant associations in any of the models.Discussion The findings bolster prior evidence that conscientious can be a protective factor against elevated AL. Conscientiousness is a possible protective factor and improving related traits can be a path to achieve better health in Latino Americans.
Sociosexuality Is Associated With Disease Avoidance Tendencies and Can Decrease During a Real-Life Disease Threat
(Springer, 2024) Sevi, Baris; Shook, Natalie J.
Engaging in uncommitted sexual relationships increases the risk of pathogen transmission through close contact with novel partners. As such, greater disease avoidance tendencies may be associated with lower sociosexuality. Across three studies, we examined this proposition. In Studies 1a and 1b, we cross-sectionally assessed the associations between individual differences in disease avoidance (i.e., germ aversion, perceived infectability) and sociosexuality dimensions (i.e., behavior, attitude, desire). Greater germ aversion was significantly associated with more restricted sociosexuality across all three dimensions and replicated in both samples. Perceived infectibility was associated with more unrestricted sociosexual attitude and desire, but only in Study 1a. In Study 2, we tested whether sociosexuality levels changed with the COVID-19 pandemic. Participants reported more restricted sociosexuality levels during the COVID-19 pandemic compared to pre-pandemic levels, where a decrease was especially seen in sociosexual desire. Further, this decrease in sociosexual desire was predicted by pre-pandemic germ aversion levels. Overall, the findings indicate that disease avoidance tendencies (i.e., germ aversion) and real-life disease threat are associated with lower tendency to engage in uncommitted sexual relationships. Further research is needed to understand the causal relation of these two constructs, which may help in developing interventions and campaigns to support better sexual health.

Interplay of Neighborhood and Psychosocial Factors in Predicting Trajectories of Allostatic Load Among Latinx Adults in the United States
(SAGE Publications Inc., 2025) Gutiérrez, Á.; Supiyev, A.; Thomas Tobin, C.; Sevi, B.; Marroig, A.; Voll, S.; Muniz-Terrera, G.
Research highlights the independent roles of neighborhood and psychosocial risk and protective factors for accelerated physiological aging. However, the combined role of neighborhood and psychosocial factors for allostatic load among Latinx adults in the U.S. remains unclear. Informed by the Health Disparities Framework, the study aims are to: (1) examine the direct associations between neighborhood (cohesion and disorder) and psychosocial (loneliness) factors, respectively, and allostatic load trajectories; and (2) determine whether family social support moderates the association between loneliness and allostatic load trajectories. Data for Latinx adults ages ≥50 (n = 319) are from the Health and Retirement Study (waves 2006–2016). Linear mixed models estimated baseline and rate of change in allostatic load, adjusting for sociodemographics. Loneliness was positively associated with baseline allostatic load. This association persisted when we considered neighborhood factors. Family social support moderated the association between loneliness and allostatic load slope. As neighborhood features, loneliness, and physiological dysregulation are each associated with worse cognitive outcomes, findings underscore the protective role of family social support for physiological dysregulation, thereby promoting cognitive resilience. © The Author(s) 2025.
Sex differences: disgust response
(Springer International Publishing, 2023) Sevi, Barış
Disgust is an emotion that involves the typical experience of a feeling of revulsion and the motivation to retract from substances that elicit disgust. Sex differences are one of its extensive study topics. Several different arguments have been provided for why a sex difference in disgust is present.
Big five personality traits: dating apps [Book Part]
(Springer International Publishing, 2023) Sevi, Barış; Bostancı, İlksen
The big five personality traits (Openness to experience, Conscientiousness, Extrovertedness, Agreeableness, and Neuroticism) are in relation with different attitudes, behaviors, and constructs, including dating apps. The big five has shown to be related to being a user of dating apps, dating app use motivations, and to different behaviors related to dating app use.

Where Should I Search Next? Messages Embedded in Storybooks Influence Children's Strategic Exploration in Turkey and the United States
(Amer Psychological Assoc, 2024) Vaisarova, Julie; Kiefer, Sarah L.; Sen, Hilal; Todd, Peter M.; Lucca, Kelsey
Despite the vital role of curiosity-driven exploration in learning, our understanding of how to enhance children's curiosity remains limited. Here, we tested whether hearing a strategic curiosity story with curiosity-promoting themes (e.g., strategically approaching uncertainty, adapting flexibly to new information) versus a control story with traditional pedagogical themes (e.g., following rules, learning from others) would influence children's strategic exploration across two cultures. Three- to 6-year-olds from the United States (N = 138) and Turkey (N = 88) were randomly assigned to hear one of these stories over Zoom, before playing a game in which they searched for sea creatures across five fish tanks. All tanks had the same number of hiding spots but varied in the number of creatures they contained. Time was limited and children could not return to prior tanks, pushing them to allocate search effort strategically. Results indicated that across both countries, children in the strategic curiosity condition explored the virtual "aquarium" more broadly; they moved through tanks more rapidly than children in the control condition and were more likely to explore all five tanks before time ran out. Children in the strategic curiosity condition also showed relatively more strategic search, adapting their search based on the likelihood of finding creatures in each tank. While further research is needed to pinpoint which elements of our stories produced differences in search behavior and whether they did so by enhancing or inhibiting children's strategic exploration, storybooks appear to be a promising method for shaping children's exploration across multiple countries.

Trust in Government Moderates the Association between Fear of COVID-19 as Well as Empathic Concern and Preventive Behaviour
(Springer Nature, 2023) Karakulak, Arzu; Tepe, Beyza; Dimitrova, Radosveta; Abdelrahman, Mohamed; Akaliyski, Plamen; Alaseel, Rana; Alkamali, Yousuf Abdulqader
With the COVID-19 pandemic, behavioural scientists aimed to illuminate reasons why people comply with (or not) large-scale cooperative activities. Here we investigated the motives that underlie support for COVID-19 preventive behaviours in a sample of 12,758 individuals from 34 countries. We hypothesized that the associations of empathic prosocial concern and fear of disease with support towards preventive COVID-19 behaviours would be moderated by trust in the government. Results suggest that the association between fear of disease and support for COVID-19 preventive behaviours was strongest when trust in the government was weak (both at individual- and country-level). Conversely, the association with empathic prosocial concern was strongest when trust in the government was high, but this moderation was only found at individual-level scores of governmental trust. We discuss how motivations may be shaped by socio-cultural context, and outline how findings may contribute to a better understanding of collective action during global crises.

Understanding Family Dynamics and Entrepreneurship: a Grounded Theory Analysis of Opportunity-Driven Entrepreneurs in Turkey
(Springeropen, 2024) İslamoğlu, Güler; Turnalar Çetinkaya, Neslihan
There is currently limited understanding of the effects of family-related factors on entrepreneurial activity. In this study, we aimed to explore characteristics of family systems among opportunity-driven entrepreneurs using a constructivist grounded theory methodology. In-depth interviews were conducted with 10 Turkish male entrepreneurs working in the technology industry and their wives. Analysis of these 20 interviews revealed a substantive conceptual model of entrepreneurs' family systems that comprised three themes reflecting the fundamentals of family life, namely marriage, the wife, and the husband. These themes included 11 categories. Our findings offer insights into the family patterns, dynamics, and demographics of entrepreneurs that have theoretical and practical implications.

Social Support and Help-Seeking Worldwide
(Springer, 2024) Szkody, Erica; Spence, Anjolee; Ozdogru, Asil; Tushir, Bhawna; Chang, Fennie; Akkas, Handan; Cascalheira, Cory J.; Karakulak, Arzu
Social support has long been associated with positive physical, behavioral, and mental health outcomes. However, contextual factors such as subjective social status and an individual's cultural values, heavily influence social support behaviors (e.g., perceive available social support, accept support, seek support, provide support). We sought to determine the current state of social support behaviors and the association between these behaviors, cultural values, and subjective social support across regions of the world. Data from 6,366 participants were collected by collaborators from over 50 worldwide sites (67.4% or n = 4292, assigned female at birth; average age of 30.76). Our results show that individuals cultural values and subjective social status varied across world regions and were differentially associated with social support behaviors. For example, individuals with higher subjective social status were more likely to indicate more perceived and received social support and help-seeking behaviors; they also indicated more provision of social support to others than individuals with lower subjective social status. Further, horizontal, and vertical collectivism were related to higher help-seeking behavior, perceived support, received support, and provision of support, whereas horizontal individualism was associated with less perceived support and less help-seeking and vertical individualism was associated with less perceived and received support, but more help-seeking behavior. However, these effects were not consistently moderated by region. These findings highlight and advance the understanding of how cross-cultural complexities and contextual distinctions influence an individual's perception, processing, and practice of social support embedded in the changing social landscape.

The Coronavirus Anxiety Scale: Cross-National Measurement Invariance and Convergent Validity Evidence
(Psychological assessment, 2024) Abdelrahman, Mohamed; Rudnev, Maksim; Adebayo, Damilola Fisayo; Karakulak, Arzu; Akaliyski, Plamen; Jovanovic, Veljko; Abdul Kadir, Nor Ba'yah
Coronavirus Anxiety Scale (CAS) is a widely used measure that captures somatic symptoms of coronavirus-related anxiety. In a large-scale collaboration spanning 60 countries (Ntotal = 21,513), we examined the CAS's measurement invariance and assessed the convergent validity of CAS scores in relation to the fear of COVID-19 (FCV-19S) and the satisfaction with life (SWLS-3) scales. We utilized both conventional exact invariance tests and alignment procedures, with results revealing that the single-factor model fit the data well in almost all countries. Partial scalar invariance was supported in a subset of 56 countries. To ensure the robustness of results, given the unbalanced samples, we employed resampling techniques both with and without replacement and found the results were more stable in larger samples. The alignment procedure demonstrated a high degree of measurement invariance with 9% of the parameters exhibiting noninvariance. We also conducted simulations of alignment using the parameters estimated in the current model. Findings demonstrated reliability of the means but indicated challenges in estimating the latent variances. Strong positive correlations between CAS and FCV-19S estimated with all three different approaches were found in most countries. Correlations of CAS and SWLS-3 were weak and negative but significantly differed from zero in several countries. Overall, the study provided support for the measurement invariance of the CAS and offered evidence of its convergent validity while also highlighting issues with variance estimation.
