Article Longitudinal Norms of Frailty Measured by the Frailty Index: A Cross-National Comparison Using Data from the Survey of Health, Aging, and Retirement in Europe (SHARE)(Elsevier, 2026) Gutierrez, Angela; Supiyev, Adil; Muniz-Terrera, Graciela; Sevi, Baris; Massa, Fernando; Marroig, AlejandraBackground: Frailty, a geriatric syndrome commonly used to identify vulnerable older adults, is a public health priority. However, the lack of cross-national comparisons of frailty trajectories and their distribution constrains current understanding of normative changes in frailty for residents across different countries. Objective: To derive longitudinal percentiles of frailty using a consistent cross-country approach. Design: Observational study using longitudinal data from the Survey of Health, Ageing and Retirement in Europe (SHARE) between 2004 and 2020. Setting: We fit the distribution of the FI by Generalized Additive Models for Location, Scale, and Shape (GAMLSS), assessed the role of sex (male/female), education (in years), and migration status (migrant/non-migrant), and estimated the longitudinal percentiles of frailty using a consistent cross-country approach for 16 countries. Participants: Individuals aged >= 65 years (N = 42,951) at study entry. Measurements: Frailty index (FI) based on the accumulation of deficits in 40 items. Results: The results show that education is protective against frailty in all countries (a decrease of 1.1 pp. in Switzerland to 5.7 pp. in Slovenia, all p < 0.001). In most countries, women are frailer than men and migrant individuals have higher levels of frailty than non-migrants. FI trajectories showed heterogeneity across countries. The quantiles for women and migrants suggest frailer trajectories than men and non-migrants respectively. Conclusions: Findings from this cross-national comparison provide a framework within which the longitudinal norms of frailty trajectories from different countries can be interpreted.Article The Relational Nature of Punishment: Responses To Close Versus Distant Others' Moral Transgressions(Sage Publications Inc, 2026) Tepe, Beyza; Faber, Nadira S.How do people respond when a close other, as opposed to a distant other, commits a moral transgression against a third person? Across five preregistered experiments (total N = 2,170), supplemented by pilot studies, we find that people navigate punishment differently depending on relational closeness: they seek less punishment by authorities (institutional punishment) for close others but impose more punishment by themselves (relational punishment) and are more likely to confront the perpetrator directly (Experiments 1-5). Moreover, transgressions of close others elicit both other-blaming and self-blaming emotions, and they prompt individuals to adopt both victim and perpetrator roles (Experiments 2-5). These effects intensify with increasing relational closeness (Experiment 3) and persist across transgressions of varying moral and criminal severity (Experiment 4).Conference Object Neighborhood and Psychosocial Predictors of Cognitive Function Among Latinos in the United States(Oxford University Press, 2025) Gutierrez, Angela; Marroig, Alejandra; Tobin, Courtney Thomas; Aranda, Maria; Camacho, David; Thorpe, Roland; Muniz-Terrera, Graciela; Sevi, BarışConference Object 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, BarisLatinos 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.Article Mice Extrapolate Temporal Information Based on Previously Learned Spatiotemporal Mappings: An Asymmetrical Case(Springer, 2026) Gur, Ezgi; Duyan, Yalcin A.; Toptas, Pinar; Balci, FuatOne 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.Conference Object Neighborhood and Psychosocial Predictors of Allostatic Load Among Latinx Adults in the United States(Oxford Univ Press, 2024) Gutierrez, Angela; Supiyev, Adil; Tobin, Courtney Thomas; Sevi, Barış; Terrera, Graciela Muniz[No Abstract Available]Article 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.; Tobin, Courtney ThomasResearch 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.Book Part Sex differences: disgust response(Springer International Publishing, 2023) Sevi, BarışDisgust 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.Article Citation - WoS: 2Where 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, KelseyDespite 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.Article Citation - WoS: 4Citation - Scopus: 9The 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; Yu, Yue; Kadir, Nor Ba'yah AbdulCoronavirus 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.
