Dataset for publication Nourishing the Brain or the Mood? Dietary Omega-3s for Psychological, but Not Cognitive Health
Dataset contains data on the relationship between omega-3 fatty rich foods and omega-3 acid intake (ALA, EPA, DHA) and mental health (mood, perceived stress) and cognitive functioning (recognition and short-term memory) in healthy adults. The data controller was SWPS University, Warsaw, Poland. Questionnaire data were collected and exported via the Qualtrics platform; the computerized cognitive tasks were administered through Pavlovia. Summary of participant characteristics and descriptive statistics: respondents - 313; variables - 206; sex - 274 women, 39 men; age: 20–90 years (mean = 40.30). Study phases: 52 participants completed the second, in-person phase, which added a cognitive screening (MMSE) and an in-depth, in-person dietary interview; the remaining 261 participated in the online Phase 1 only. Two files are provided: the dataset (.xlsx) and a codebook (.xlsx) listing each variable's name, label, type, valid/missing counts, and range or value coding. - 2026-06-05
Narcissism and self- esteem as predictors of exchange and communal relational orientations
Interpersonal relationships vary in the extent to which they are regulated by communal norms of care and responsiveness versus exchange norms emphasizing proportionality and reciprocity. Although the consequences of these relational orientations are well-documented, their antecedents remain less well understood. We examined whether communal and exchange orientations reflect distinct self-regulatory strategies rooted in adaptive versus maladaptive forms of self-evaluation. In Study 1 (U.S. sample, N = 452), communal orientation toward a close relationship partner was positively associated with self-esteem and negatively associated with narcissism, whereas exchange orientation showed the opposite pattern, being strongly linked to narcissism and largely unrelated to self-esteem. Preregistered Study 2 (N = 1791, conducted in United States and South Africa) used a within-person design across multiple relationship targets. Multilevel structural equation modeling showed that relational closeness was a strong predictor of communal orientation but a weaker predictor of exchange orientation. Exchange orientation was consistently predicted by both grandiose and vulnerable narcissism, particularly in close relationships, whereas communal orientation was only weakly related to individual differences. These findings suggest that communal orientation is primarily relationship-driven, whereas exchange orientation reflects a more stable, personality-linked strategy for regulating dependence and vulnerability in social relationships. - 2026-05-26
Awareness shapes fairness: how Children’s emotion atributions reflect sensitivity to unequal treatment
How do children reason about fairness when transgressors receive different consequences for the same misdeed? In a pre-registered study with N = 122 participants at 6 to 9 years, we investigated how children evaluate unequal norm enforcement (punishment vs. leniency) and how they integrate a transgressor’s knowledge state about the inequality into their emotion attributions. Results showed that children revised their emotion attributions depending on whether the transgressor was aware of being treated differently. Children initially attributed happiness to an unpunished transgressor or sadness to a punished transgressor. However, they subsequently attributed mixed emotions such as guilt or sadness combined with relief to transgressors who learned about the inequality but not to transgressors who only knew about the punishment to the self. These results suggest that children reflect not only on the consequences to the individual but also on the transgressors’ knowledge about whether a meta-norm of equality has been violated. - 2026-06-01
Association between life satisfaction and selected socio-demographic factors and social and professional activity – a comparative study between patients with Crohn’s disease and patients with ulcerative colitis
Introduction: Inflammatory bowel diseases (IBD) substantially affect patients’ physical, psychological, and social functioning. Although numerous studies have evaluated health-related quality of life in IBD, comparatively fewer investigations have focused specifically on life satisfaction and its relationship with socio-demographic characteristics. Aim: The study aimed to compare patients with Crohn’s disease (CD) and ulcerative colitis (UC), assess their level of life satisfaction, and evaluate its association with selected socio-demographic factors and social and professional activity. Material and methods: This comparative study included 109 patients with CD and 101 patients with UC. The inclusion criteria were a diagnosis of IBD and an age of 18–85 years. The patients were recruited from the Clinical Department of Gastroenterology and Hepatology and the Outpatient Gastroenterology Department of the University Hospital of Krakow. Results: The study did not reveal any differences between the groups in mean life satisfaction. No significant differences were observed regarding the effects of the diseases on social and professional activity. The CD patients demonstrated statistically significant differences in their life satisfaction by education level. The satisfaction level of UC subjects was significantly affected by their place of residence. Both CD and UC increased the need to restrict or withdraw from professional life, limiting social contacts. The decrease in Satisfaction with Life Scale (SWLS) was most affected by the deterioration of social standing; the least dependence was observed for the necessity of limiting one’s professional life. Conclusions: Both CD and UC patients report similar levels of life satisfaction, as both conditions have a comparable impact on their social and work lives. The patients are apprehensive about their future and are forced to limit their present professional involvement or withdraw from their professional life.

Psychologia społeczna. Wydanie drugie zaktualizowane
Nowa wersja podręcznika Psychologia społeczna ukazuje się w 14 lat po jego pierwszej edycji. Później było wiele wydań, bo podręcznik zyskał powszechne uznanie wykładowców i studentów. To wydanie jednak zasadniczo różni się od poprzednich. Współautorem został Tomasz Grzyb. W tomie przybyło wiele nowych fragmentów, niektóre kwestie zaktualizowano bądź opatrzono dodatkowymi komentarzami, odwołując się do świeżej literatury. Przede wszystkim zmienił się świat dookoła nas, pojawiły się nowe zjawiska, jak na przykład światowa pandemia COVID-19 i wraz z tym potrzeba odniesienia się do jej psychologicznych konsekwencji, a o wielu zjawiskach, którymi zajmuje się psychologia społeczna wiemy dziś więcej niż kilkanaście lat temu. Nie pozostało to bez wpływu na sam podręcznik – jego nowa, zmodyfikowana i przeredagowana treść lepiej oddaje charakter zmieniającej się, choć ciągle tak samo fascynującej dziedziny, jaką jest psychologia społeczna. Profesorowie Bogdan Wojciszke i Tomasz Grzyb, psychologowie o światowej renomie, napisali podręcznik do psychologii społecznej, jakiego jeszcze w Polsce nie było. Książka obejmuje wszystkie klasyczne zagadnienia składające się na tę dyscyplinę oraz zagadnienia relatywnie nowe, takie jak kwestie różnic płci, nowych mediów, społeczeństwa sieci, miłości i władzy. Napisana jasnym i barwnym językiem skupia się na prawidłowościach rządzących ludzką psychiką i postępowaniem. Pokazuje, w jak fascynujący sposób psychologia społeczna odpowiada na pytanie, kim jest człowiek i na czym polega jego społeczna natura. Wcześniejsze wydania tej książki stały się fundamentem dydaktyki akademickiej na kierunku psychologia. - 2025-08-11
What Puppygirls Know? The (in)Human Pedagogy of a Trans Feminine Style
‘Puppygirls’ is a name for a particular kinky trans feminine lesbian style, rooted in the long history of trans erotic productions, and currently thriving on social media platforms, such as Twitter (now X), Bluesky, or Discord. In this article, I provide an analysis of the style that is rooted in personal immersion in ‘puppygirl culture’. Using several examples of puppygirl media productions, I argue for the possibility of reading the puppygirl style as a critical practice: one that hints at ways of being trans that do rely on the ciscentric understanding of ‘the human’ as their point of reference. In doing so, I show how puppygirl style resonates with theoretical interventions in the field of trans studies offered by scholars such as Susan Stryker and Talia Mae Bettcher. - 2023

The Big Three Perfectionism Scale: Validation of the Polish Version
The Big Three Perfectionism Scale (BTPS) was created to integrate different aspects of perfectionism, including the newly conceptualized concept of narcissistic perfectionism. The goal of our two studies (N = 1341) was to examine the psychometric properties of the Polish adaptation of the BTPS, supporting the validity and portability of the measure. The studies were conducted among people who had a child, thus contributing to a better understanding of parental perfectionism, one of the key factors influencing parental well-being and a child’s functioning. Our analyses included investigating the structure of the scale, intercorrelations between subscales, reliability, and convergent validity by correlating BTPS scores with other measures of perfectionism and correlates of psychopathology (borderline symptoms) and parental difficulties (parental stress and parental burnout). Results supported the structure of the original BTPS. As predicted, confirmatory factor analysis indicated that items comprising the Polish adaptation of the questionnaire, like the original version, measure three related but specific aspects of perfectionism: rigid perfectionism, self-critical perfectionism, and narcissistic perfectionism. The three dimensions were also found to be specifically related to the difficulties experienced by parents. Further, the Polish version of the BTPS was found to have good internal reliability and validity. Our results from two independent Polish samples suggest that the Polish version of the BTPS is a psychometrically robust measure of perfectionism for assessing the three perfectionism factors.
