Affective Interpersonal Touch in Close Relationships: a Cross-Cultural Perspective
(Sage Publications Inc, 2021) Sorokowska, Agnieszka; Saluja, Supreet; Sorokowski, Piotr; Frackowiak, Tomasz; Karwowski, Maciej; Aavik, Toivo; Akello, Grace; Can, Seda; Croy, Ilona
Interpersonal touch behavior differs across cultures, yet no study to date has systematically tested for cultural variation in affective touch, nor examined the factors that might account for this variability. Here, over 14,000 individuals from 45 countries were asked whether they embraced, stroked, kissed, or hugged their partner, friends, and youngest child during the week preceding the study. We then examined a range of hypothesized individual-level factors (sex, age, parasitic history, conservatism, religiosity, and preferred interpersonal distance) and cultural-level factors (regional temperature, parasite stress, regional conservatism, collectivism, and religiosity) in predicting these affective-touching behaviors. Our results indicate that affective touch was most prevalent in relationships with partners and children, and its diversity was relatively higher in warmer, less conservative, and religious countries, and among younger, female, and liberal people. This research allows for a broad and integrated view of the bases of cross-cultural variability in affective touch.

Affective Reactions To One's Whole Life: Preliminary Development and Validation of the Ontological Well-Being Scale
(Springer, 2013) Simsek, Omer Faruk; Kocayoruk, Ercan
In line with the perspective provided by the intentional paradigm which claims that the measures of subjective well-being (SWB), whether cognitive or affective, should refer to life itself, the Ontological Well-Being Scale (OWBS) has been operationalized. The research reported herein was aimed at developing and validating this psychometric tool in the assessment of individuals' affective evaluations of their life within a three-time perspective. Five studies were conducted to confirm the factor structure of the OWBS and to assess its construct validity. Four factors were derived and validated, which were shown to relate to mental health indicators and personality in expected ways. It was found that this new construct, in contrast with the current measures, did not tap into the personality factors of extraversion and neuroticism. Incremental validity results showed that the OWBS explained additional variance in mental health indicators already captured by the current measures of SWB.

Aging Attenuated Theta Response During Multistable Perception
(Wiley, 2023) Küçük, Kurtulus Mert; Mathes, Birgit; Schmiedt-Fehr, Christina; Başar Eroğlu, Canan; Başar-Eroğlu, Canan
Multistable stimuli are physically unchanging, but elicit spontaneous perceptual reversals between multiple internally generated perceptual alternatives. Perceptual reversal rates seem to decrease in older adults; however, there is no literature on the electrophysiological correlates of this performance decrease. Here, we aimed to identify age-related changes in theta activity that relate to decreased reversal rates of older adults. Electroencephalography (EEG) of young (n = 15) and older adults (n = 15) was recorded during presentation of stroboscopic alternative motion (SAM) and a control stimulus. Time-frequency amplitudes were extracted in 4-8 Hz via Morlet wavelet convolution. Older adults had lower SAM reversals as well as decreased accuracy, increased reaction time (RT) and increased RT variability in the control task. In older adults, reversal-related frontal theta response was diminished, yet parietal theta was intact. In the parietal area, the relationship between theta response and reversal rates was robust, but in the frontal area, was dependent on age-related variance. Result indicated that, in older adults, top-down facilitation of perceptual reversals was impaired. This appears to result in a predominantly bottom-up resolution of perceptual multistability. Age-related degradation of sensory areas in this bottom-up-driven resolution process might have slowed reversals. This study presents the first electrophysiological correlates of age-related impairment in multistable perceptual integration.

Altered Gamma and Theta Oscillations During Multistable Perception in Schizophrenia
(Elsevier, 2020) Rurup, Linda; Mathes, Birgit; Schmiedt-Fehr, Christina; Wienke, Annika Susann; Ozerdem, Aysegul; Brand, Andreas; Başar Eroğlu, Canan; Basar-Eroglu, Canan
Objective: Coherent object perception in patients with schizophrenia is known to be impaired. Oscillatory brain dynamics constitute a fundamental mechanism for the coordinated communication of neural circuits. Such dynamics have been proposed to reflect impaired spatio-temporal integration of sensory and cognitive processes during object perception in schizophrenia. Method: EEG recordings of patients with schizophrenia (n = 23) and control participants (n = 23) were examined. Presented were either an ambiguous (multistable) stimulus, endogenously inducing switching between two perceptual alternatives, or a slightly modified unambiguous control stimulus, during which perceptual reversals were triggered by a minor change in the stimulus configuration. Event-related amplitude modulation induced by perceptual reversals was analyzed for theta (3-8 Hz) and gamma band oscillations (28-48 Hz). Results: Patients displayed increased reaction times and more errors when indicating unambiguous reversals. The patients ' amplitude enhancement of theta oscillations was diminished in both task conditions. During the control task were gamma amplitudes larger in patients than in healthy participants. Conclusion: The results indicate that impairments in generating coherent percepts are reflected in alterations of multiple frequency bands and time windows. Changes in gamma band oscillations may reflect the patients' impairments in perceptuo-cognitive integration processes. Diminished theta amplitude modulation in patients further emphasize diminished top-down cognitive control during perceptual reversals. Significance: This study provides insight into how theta and gamma oscillations underlie changes in object perception, and thereby possibly the generation of core symptoms, in schizophrenia. This paper is dedicated to Prof. Dr. Erol Basar, a pioneer in research on oscillatory braindynamics. He was tireless in his effort to understand brain functions and integratedphilosophy, physics, biology and psychology in his research. His vision on how informationis coded in brain networks inspired many researchers in the last 40 years. With him, we not only lose an exceptional researcher, but also a supportive academic teacher and mentor with a persistent, prolific enthusiasm for international and collaborative projects.

An Analysis of Change Over Time: Latent Growth Models
(Turkish Psychologists Assoc, 2010) Dural, Seda; Somer, Oya; Korkmaz, Mediha; Can, Seda; Ogretmen, Tuncay
Latent Growth Models which are used in understanding how individuals change over time have been a topic of intense interest among the researchers during the past two decades. These models in the framework of Structural Equation Modeling have been recommended as an alternative to classical methods such as analysis of variance. In this study, Latent Growth Models were introduced by using a Monte Carlo simulation approach and the interpretation of the findings was discussed. In addition, the effect of different sample sizes (30, 50, 100, and 200) on power and parameter estimates were examined. For this purpose; (1) data generation was performed with Monte Carlo simulation, (2) the parameters of unconditional and conditional models were estimated and the findings were discussed and (3) the effect of sample size on parameter estimates, standard errors, coverage and power was studied. All of the analyses were performed by using Mplus 5.1 software. Results were discussed in the context of advantages and disadvantages of Latent Growth Models, and the effect of sample size.

Antecedents of Organizational Citizenship Behavior Among Turkish White-Collar Employees in the Netherlands and Turkey
(Pergamon-Elsevier Science Ltd, 2015) Ersoy, Nevra Cem; Derous, Eva; Born, Marise Ph.; Van der Molen, Henk T.
This study examined antecedents of organizational citizenship behavior (i.e., reward for application; religiosity beliefs and employees' relational identification with their supervisor) among Turkish white-collar employees in The Netherlands (n=103) and Turkey (n = 147). OCB related positively to reward for application (both samples) but not to religiosity beliefs among Turkish employees in their home country (Turkey). As expected, relational identification with the supervisor was less strongly related to organizational citizenship behavior among Turkish white-collar employees in their host country (The Netherlands) compared to their home country (Turkey), especially when they resided longer in their host country. Giving increasing globalization and war for talent, findings are relevant to better understand effects of white-collar migrants' cultural background and acculturation patterns in work-related domains, like OCB.

The Associations of Dyadic Coping and Relationship Satisfaction Vary Between and Within Nations: a 35-Nation Study
(Frontiers Media Sa, 2016) Hilpert, Peter; Randall, Ashley K.; Sorokowski, Piotr; Atkins, David C.; Sorokowska, Agnieszka; Ahmadi, Khodabakhsh; Aghraibeh, Ahmad M.; Dural, Seda
Objective: Theories about how couples help each other to cope with stress, such as the systemic transactional model of dyadic coping, suggest that the cultural context in which couples live influences how their coping behavior affects their relationship satisfaction. In contrast to the theoretical assumptions, a recent meta-analysis provides evidence that neither culture, nor gender, influences the association between dyadic coping and relationship satisfaction, at least based on their samples of couples living in North America and West Europe. Thus, it is an open questions whether the theoretical assumptions of cultural influences are false or whether cultural influences on couple behavior just occur in cultures outside of the Western world. Method: In order to examine the cultural influence, using a sample of married individuals N = 7973) from 35 nations, we used multilevel modeling to test whether the positive association between dyadic coping and relationship satisfaction varies across nations and whether gender might moderate the association. Results: Results reveal that the association between dyadic coping and relationship satisfaction varies between nations. In addition, results show that in some nations the association is higher for men and in other nations it is higher for women. Conclusions: Cultural and gender differences across the globe influence how couples' coping behavior affects relationship outcomes. This crucial finding indicates that couple relationship education programs and interventions need to be culturally adapted, as skill trainings such as dyadic coping lead to differential effects on relationship satisfaction based on the culture in which couples live.

Assortative Mating and the Evolution of Desirability Covariation
(Elsevier Science Inc, 2019) Conroy-Beam, Daniel; Roney, James R.; Lukaszewski, Aaron W.; Buss, David M.; Asao, Kelly; Sorokowska, Agnieszka; Sorokowski, Piotr; Can, Seda; Zupančič, Maja
Mate choice lies dose to differential reproduction, the engine of evolution. Patterns of mate choice consequently have power to direct the course of evolution. Here we provide evidence suggesting one pattern of human mate choice-the tendency for mates to be similar in overall desirability-caused the evolution of a structure of correlations that we call the d factor. We use agent-based models to demonstrate that assortative mating causes the evolution of a positive manifold of desirability, d, such that an individual who is desirable as a mate along any one dimension tends to be desirable across all other dimensions. Further, we use a large cross-cultural sample with n = 14,478 from 45 countries around the world to show that this d-factor emerges in human samples, is a cross-cultural universal, and is patterned in a way consistent with an evolutionary history of assortative mating. Our results suggest that assortative mating can explain the evolution of a broad structure of human trait covariation.

Asymmetry of Visually Guided Sexual Behaviour in Adult Japanese Quail (coturnix Japonica)
(Psychology Press, 2007) Gulbetekin, Evrim; Gunturkun, Onur; Dural, Seda; Çeti̇nkaya, Hakan
Sexually active adult Japanese quail (Coturnix coturnix japonica) were trained to run across either it left- or a right-turning runway to obtain sexual access to a conspecific of the opposite sex. The birds tested with only their right eye in use showed significantly higher latencies to complete the runway task than the birds tested binocularly and those using the left eye. In all of the three experimental conditions, male birds were significantly faster than their female counterparts. Generally, these findings are compatible with previous evidence for lateralisation in sexually motivated behaviour in birds. However, unlike the previous findings that Suggested a loss of lateralisation in pattern discrimination in quail during adulthood, the present study shows that asymmetries in visually guided sexual behaviour persist in adult quail. Thus, our study implies that ontogenetic and lateralised changes within the visual system can be differently organised for different output pathways.

Attractiveness of Leg Length: Report From 27 Nations
(Sage Publications Inc, 2011) Sorokowski, Piotr; Szmajke, Andrzej; Sorokowska, Agnieszka; Cunen, Maryann Borg; Fabrykant, Marharyta; Zarafshani, Kiumars; Amiri, Manochehr; Çeti̇nkaya, Hakan
The leg-to-body ratio (LBR) is a morphological index that has been shown to influence a person's attractiveness. In our research, 3,103 participants from 27 nations rated the physical attractiveness of seven male and seven female silhouettes varying in LBR. We found that male and female silhouettes with short and excessively long legs were perceived as less attractive across all nations. Hence, the LBR may significantly influence perceptions of physical attractiveness across nations.

Basic Psychological Needs Satisfaction and Frustration Scale (Bpnsfs): a Turkish Adaptation Study
(Wiley, 2025) Kocak, Aylin; Mouratidis, Athanasios; Christ, Aysenur Alp; Michou, Aikaterini; Sayil, Melike; Alp Christ, Ayşenur
This two-wave study aimed to adapt the Basic Psychological Needs Satisfaction and Frustration Scale (BPNSFS) to the Turkish language and cultural context. At Time 1, participants included 1033 Turkish high school students (Mage = 15.91, SD = 0.36; 41.9% female) from 26 public schools located in Ankara, T & uuml;rkiye. At Time 2, 849 students continued to participate in the study. A series of CFA provided support to the originally proposed six-factor solution of the BPNSFS and its time invariance along a 6-month period. The results also revealed that in addition to the six-factor model, the Multi-Trait, Multi-Method (MTMM) model could also be used in future research. In addition, testing the reliability and validity of the scale, regression analyses showed that satisfaction of the three needs positively predicted life satisfaction and negatively predicted depressive feelings, while an opposite trend was observed for the need frustration. Our findings suggest that the Turkish version of the scale is reliable and carries similar psychometric features to the original version.

Bodily Self-Consciousness in Dreams Questionnaire (bsd-Q) and Its Relation To Waking Dissociative Experiences
(Educational Publishing Foundation-American Psychological Assoc, 2022) Erdeniz, Burak; Tekgun, Ege; Mentes, Ozge; Coban, Aslihan; Bilge, Selma; Serin, Emin
According to virtual reality dream theory (Hobson & Friston, 2014), while dreaming, brains generate a dream world similar to a virtual reality environment, and this world uses the same predictive self/world modeling capacity as that used during wakefulness. The theory proposes that phenomenology of dreaming experience is based on the waking experience, a view widely accepted by dream researchers. In the current research, we argued that individuals with different intensities of dissociative experiences during waking, will report corresponding differences in the profoundness of sensory modality experiences, such as touching in dreams. To test this hypothesis, first we developed a novel Bodily Self-Consciousness in Dreams Questionnaire, that was completed by 414 participants. The questionnaire measured the intensity of different sensory modality experiences in past dreams. The results showed that a four-factor solution explains 64% of the total variance, and yielded sufficient reliability with McDonald's to ranging from .62 to .84, and Cronbach's a ranged from .61 to .84. Along with the Bodily Self-Consciousness in Dreams Questionnaire, we administered the Dissociation Questionnaire (Vanderlinden et al, 1993), which showed a significant positive correlation between the bodily self-consciousness in dreams and dissociative experiences during waking. In conclusion, the results showed that all of the modalities pertain to bodily self-consciousness in dreams and are significantly correlated with waking state dissociative experiences.
Bound by Society: An Exploratory Study of Pet Attachment and Social Constraints in Pet Bereavement Among a Turkish Sample
(Routledge Journals, Taylor & Francis Ltd, 2025) Demirci, Oyku; Yuksel, Ozge; Meral, Yasemin
Pet owners often form deep emotional bonds with their animals, and the death of a pet can elicit grief responses similar to human loss. However, pet loss is often considered disenfranchized grief, socially unrecognized and unsupported. Guided by social-cognitive processing and attachment perspectives, this study examines how pet attachment, social constraints, and loss-related variables shape grief intensity. The study included 210 adults who lost a pet within the past year and completed measures of pet bereavement, attachment to pets, and social constraints. Attachment to the pet was the strongest predictor of grief severity, while social constraints also influenced grief, with those facing emotional inhibition experiencing greater distress. Loss-related factors such as euthanasia initially predicted grief, but their effect diminished once attachment and social constraints were considered. These findings emphasize the multifaceted nature of pet loss grief and the need for greater societal recognition and support for the bereaved pet owners.
