Article Mice Extrapolate Temporal Information Based on Previously Learned Spatiotemporal Mappings: An Asymmetrical Case(Springer, 2026-01-06) 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, 2025-08-28) 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., 2025-08-06) 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, 2025-12-01) 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 - WoS: 11Citation - Scopus: 11Unheard Voices of Lgb People in Türkiye on Lgb-Specific Experiences of Intimate Partner Violence: a Qualitative Analysis(Sage Publications inc, 2024-04-17) 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, 2024-02-05) 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.Article Citation - WoS: 6Citation - Scopus: 4Favoring Inequalities and Mind-Reading: Social Dominance Orientation Relates To Poor Mentalizing(Sage Publications Inc, 2023-07-21) Ekerim-Akbulut, Müge; Selçuk, BilgeAlthough studies have so far investigated social dominance orientation (SDO) in relation to its association with prejudice and discrimination toward outgroups, it is not known whether SDO's link with poor intergroup relations might be underlined by specific socio-cognitive factors such as reduced mind-reading motivation (MRM) and poor mind-reading performance. The present study tested whether endorsement of SDO is associated with decreased MRM and mind-reading accuracy toward both ingroup and outgroup targets. We randomly assigned one hundred and 20 Turkish university students (M- age = 22.02) into two target groups for mind-reading, Turkish ingroup (N = 60) and Syrian outgroup (N = 60), and asked them to infer minds of either ingroup or outgroup members depending on their target group. Participants also reported their level of MRM and SDO through questionnaires. When the target was a Turkish ingroup member, SDO negatively and directly predicted mind-reading, when the target was an outgroup member, however, higher SDO indirectly predicted lower mind-reading through reduced MRM. These results pointed that favoring intergroup hierarchies relates to poor understanding of others' mental states although the mechanism of the relation changes depending on the group membership of the target.Article Citation - WoS: 8Citation - Scopus: 8But the Poor Needed It More: Children's Judgments on Procedural Justice To Allocate Resources Between Two Candidates Equal in Merit, Different in Need(Elsevier Science Inc, 2023-08-01) Sıvış, Özce; Acar, MelikeThe current study investigated children's judgments on procedural justice and its outcomes when the candidates were equal in merit but different in need. A total of 88 children (41 girls and 47 boys) aged 7 to 11 years were individually interviewed (Mage = 8 years 9 months, SD = 14.065 months). Results showed that, regardless of age, children tended to give educational resources to the resource-poor candidates. However, children's welfare considera-tion of the resource-poor candidates increased with age. Children also made differentiated judgments based on the resource type and treated educational materials as more necessary than educa-tional experiences. Children's age and socioeconomic status (SES) were associated with this differentiation. Younger and high-SES children were more likely to view the outcome of procedural jus-tice (i.e., drawing a stick) for allocating an educational experience (i.e., summer camp) as fair when the result favored the resource -rich candidate. Overall, findings revealed that children do not use a unitary form of fairness in the procedural justice context. The shift from strict equality to welfare concerns continues to develop over middle childhood. (c) 2023 Elsevier Inc.

This has been achieved by adaptive scaling of human force based on her/his movement intention while paying attention to the requirements of different task phases. In our approach, movement intentions of human are estimated from measured human force and velocity of manipulated object, and converted to a quantitative value using a fuzzy logic scheme. This value is then utilized as a variable gain in an admittance controller to adaptively adjust the contribution of robot to the task without changing the admittance time constant. We demonstrate the benefits of the proposed approach by a pHRI experiment utilizing Fitts’ reaching movement task. The results of the experiment show that there is a) an optimum admittance time constant maximizing the human force amplification and b) a desirable admittance gain profile which leads to a more effective co-manipulation in terms of overall task performance.Article Citation - WoS: 22Citation - Scopus: 23Culturally Shared and Unique Meanings and Expressions of Maternal Control Across Four Cultures(American Psychological Association, 2021-02-01) Selçuk, Bilge; Cheah, Charissa S L; Şen, Hilal H.; Park, Seong-Yeon; Vu, Kathy T T; Cho, Hyun Su; Yavuz, H MelisMaternal control is a major dimension of parenting and has different meanings, practices, and potential consequences across cultures. The present study aimed to identify and compare mothers' conceptualizations of parenting control across four cultures to reveal a more nuanced understanding regarding the meaning and practices of control: European American, Chinese immigrant, Korean immigrant, and Turkish. Using a semistructured open-ended interview, 100 European American, 102 U.S. Chinese immigrant, 103 U.S. Korean immigrant, and 109 Turkish mothers of preschool-aged children reported the ratings of importance, specific reasons, and strategies for exerting control over their children in daily life. Results revealed both shared and unique conceptualizations of maternal control across four cultures. Specifically, all mothers reported that it is important to express maternal control over their children in order to set behavioral norms/standards, maintain child safety, support social relations and respect for others, provide guidance, and guide moral development. Moreover, mothers discussed utilizing nonphysical punishment, setting and maintaining rules, reasoning/negotiating, consistency, physical punishment and verbal control, showing parents' serious/stern attitude, correction, and psychological control forms of control. However, the levels at which mothers emphasize the different reasons and strategies varied across cultures, reflecting culturally emphasized values. The findings of the present study further enrich our understanding of the complexities of maternal control across cultures. (PsycInfo Database Record
