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.Article Citation - WoS: 1Longitudinal Relations Between Early Prosocial Behaviors Toward Parents and Later Prosocial and Aggressive Behaviors in Turkish Early Adolescents(Amer Psychological Assoc, 2025) Gulseven, Zehra; Kumru, Asiye; Carlo, Gustavo; Maiya, Sahitya; Sayil, Melike; Selcuk, BilgeBecause Turkish early adolescents learn and practice many essential prosocial behaviors (i.e., helping, sharing) within the family context, it is important to examine whether early adolescents' prosocial behaviors toward parents at age 10 (Time 1) were related to their later prosocial and aggressive behaviors at age 13 (Time 3) via perceived parental psychological control at age 12 (Time 2). Participants were 355 early adolescents (M-age = 9.89 years, SD = 0.32; 51% girls) from Türkiye at Time 1. Early adolescents reported their prosocial behaviors toward mothers and fathers at age 10, perceived maternal and paternal psychological control at age 12, and prosocial and aggressive behaviors at age 13. Mediation analyses showed that early adolescents' greater prosocial behaviors toward parents were significantly related to less perceived psychological control, which, in turn, was related to less altruistic and reactive prosocial behaviors but related to greater reactive and proactive aggressive behaviors. Importantly, these associations were robust across boys and girls, and all indirect effects were statistically significant. The findings inform theories that suggest interindividual stability in youth's levels of prosocial behavior and reciprocal relations between parenting and youth behaviors but extend such findings to a non-Western, relatively collectivist-oriented, predominantly Muslim culture.Article Citation - WoS: 1Citation - Scopus: 1Body Appreciation Matters: The Associations Between Self-Compassion, Body Appreciation, and Disordered Eating Behaviors Among Heterosexual and LGBI+ Emerging Adults in Türkiye(SAGE Publications Inc., 2025) Deveci, A.N.; Toplu-Demirtaş, E; Bulgan, G.; Toplu Demirtaş, Ezgi; Demirtas, Ezgi TopluObjectives: Self-compassion has been effective in the prevention and treatment of disordered eating behaviors and body image issues, which are significant public health concerns with potential psychosocial and physical consequences. Furthermore, there remains a substantial gap in the existing body of research, particularly in the context of heterosexual, lesbian, gay, and bisexual plus (LGBi+) emerging adults in Türkiye. Therefore, this study aims to explore the mediating role of body appreciation in the relationship between self-compassion and disordered eating behaviors and the moderating role of sexual orientation (heterosexual and LGBi+) in the mediation among emerging adults. Methods: A diverse sample of participants comprising heterosexual (n = 242) and LGBi+ (n = 204) emerging adults (Mage = 22.18; SDage = 3.07; min = 18; max = 30) completed self-report measures of the Self-Compassion Scale, Body Appreciation Scale-2, and Eating Attitude Test-26. Results: The results of moderated meditation revealed that body appreciation mediated the relationship between self-compassion and disordered eating behaviors among both heterosexual and LGBi+ individuals. Conclusions: The findings may inform support strategies and interventions to reduce eating disorder risk and promote mental health and well-being in both heterosexual and LGBi+ populations by emphasizing self-compassion and body appreciation. © The Author(s) 2025Article Citation - WoS: 1Citation - Scopus: 1When Words and Pointing Compete: Young Children's Referential Comprehension Under Uncertainty(Elsevier Science Inc, 2025) Ates, A. Beyza; Kuntay, Aylin C.The present research comprised two studies examining how 2- to 4-year-old children resolve referential uncertainty. Study 1 investigated first touches-objects initially selected or touched immediately-and takeaways-objects ultimately selected or given-as two distinct object selection behaviors, along with the verbal responses accompanying them. Study 2 explored how communicative context (i.e., preactivation of familiar object labels prior to object selection) and child characteristics (i.e., age, vocabulary knowledge, and selective attention) influenced children's referential strategies. Using a modified version of Grassmann and Tomasello's (2010) paradigm, two experimental conditions were implemented: In the Familiar-Familiar condition, when presented with two familiar objects, Experimenter 1 labeled one object to be given to Experimenter 2, while pointing to the other. In the Novel-Familiar condition, when presented with one novel and one familiar object, Experimenter 1 used a novel label while pointing to the familiar object. Results demonstrated that ostensive pointing was a stronger cue than verbal labeling in guiding children's object selections. Children modified their selections between first touches and takeaways in 17-34% of trials or verbally responded to the contradiction in 13-40% of trials. Furthermore, preactivation of familiar object labels and individual characteristics-particularly age and selective attention-were linked to variations in referential strategies. These findings highlight the complexity of referential resolution, where children integrate verbal and nonverbal cues, providing nuances about communicative development and insights about how it could be supported.Article Citation - Scopus: 1High School and University Students' Reasoning About Decision-Making Autonomy and Parental Authority Legitimacy in Child–Mother Conflicts(WILEY, 2025) Kuyel, N.; Acar, M.This study investigated youths' reasoning about personal autonomy and maternal authority in hypothetical emerging adult child–mother conflicts in Türkiye. High school and university students (N = 138, Mage = 19.72 years) from secular and religious schools completed a self-report questionnaire including eight conflict scenarios where the mother opposes her child's decision to marry a non-Muslim or get a tattoo. Maternal opposition in hypothetical scenarios was presented in the forms of maternal advice and maternal use of haram opposition. Haram opposition implies the declaration of maternal accrued rights (a concept deeply rooted in Turkish culture) as haram. The results showed that participants were more likely to subordinate child autonomy to maternal authority when the mother in hypothetical scenarios was depicted as using haram opposition. Authoritative parenting appeared to strengthen this effect. This study has shown that haram opposition is a psychological control mechanism to subordinate child autonomy to maternal authority. © 2025 British Psychological Society.Article Citation - WoS: 11Citation - Scopus: 11Unheard Voices of Lgb People in Türkiye on Lgb-Specific Experiences of Intimate Partner Violence: a Qualitative Analysis(Sage Publications inc, 2024) Demirtaş, Ezgi Toplu; Ummak, Esra; Özkan, Hande; Toplu Demirtaş, EzgiDrawing upon in-depth, semistructured interviews with 26 LGB participants, we explored how LGB individuals experience IPV uniquely in Turkiye. Conducting thematic analysis, we generated four themes: (a) invalidation of sexual identity, (b) controlling sexuality and sexual behaviors, (c) disclosure of sexual orientation, and (d) binegativity. The analysis emphasizes LGB-specific power dynamics influencing IPV. A discussion is provided regarding the extent to which these four themes are specific to IPV in LGB relationships. Additionally, recommendations are offered to mental health professionals on tailoring their approaches and promoting advocacy for the needs of LGB IPV survivors.Article Citation - WoS: 2Citation - Scopus: 4Unlocking the Neural Mechanisms of Consumer Loan Evaluations: an Fnirs and Mlbased Consumer Neuroscience Study(Frontiers Media SA, 2024) Girişken, Yener; Son, Semen; Demircioğlu, Esin Tuna; Filiz, Gözde; Çakar, Tuna; Ertuğrul, Seyit; Sayar, Alperen; Tuna, Esin; Son-Turan, SemenThis study conducted a comprehensive exploration of the neurocognitive processes underlying consumer credit decision-making using cutting-edge techniques from neuroscience and artificial intelligence (AI). Employing functional Near-Infrared Spectroscopy (fNIRS), the research examines the hemodynamic responses of participants while evaluating diverse credit offers. The study integrates fNIRS data with advanced AI algorithms, specifically Extreme Gradient Boosting, CatBoost, and Light Gradient Boosted Machine, to predict participants' credit decisions based on prefrontal cortex (PFC) activation patterns. Findings reveal distinctive PFC regions correlating with credit behaviors, including the dorsolateral prefrontal cortex (dlPFC) associated with strategic decision-making, the orbitofrontal cortex (OFC) linked to emotional valuations, and the ventromedial prefrontal cortex (vmPFC) reflecting brand integration and reward processing. Notably, the right dorsomedial prefrontal cortex (dmPFC) and the right vmPFC contribute to positive credit preferences. This interdisciplinary approach bridges neuroscience and finance, offering unprecedented insights into the neural mechanisms guiding financial choices. The study's predictive model holds promise for refining financial services and illuminating human financial behavior within the burgeoning field of neurofinance. The work exemplifies the potential of interdisciplinary research to enhance our understanding of human financial decision-making.
