Biological Essentialism in Parenting: Validating a Cross-Cultural Measure across Diverse Family Structures
This study introduces and validates the Biological Essentialism in Parenting Questionnaire (BEPQ), a new instrument designed to assess beliefs that men and women possess inherent, biologically determined differences in parenting roles. Despite evolving norms favoring gender-equal parenting, essentialist views continue to influence family dynamics, workplace policies, and cultural expectations. In Study 1 (N = 488, Poland), we developed the BEPQ and confirmed a two-factor structure, distinguishing maternal and paternal essentialism, through exploratory factor analysis. Both subscales demonstrated high internal consistency and negative correlations with gender-neutral parenting beliefs, supporting their reliability and convergent validity. Study 2 (N = 1249) extended validation to parents in Poland, Italy, and Sweden. Confirmatory factor analysis and multigroup modeling established strict measurement invariance across countries and gender identities, ensuring robust cross-cultural applicability. Findings showed that Polish parents most strongly endorsed essentialist beliefs, followed by Italian and then Swedish parents. Heterosexual parents reported stronger essentialist views than LGBTQ+ parents, men showed higher paternal essentialism, and women endorsed maternal essentialism more strongly, with non-binary parents consistently reporting the lowest levels across both dimensions. By providing a reliable and cross-culturally validated tool, the BEPQ advances research on how biological essentialist ideologies maintain gendered caregiving roles within diverse family structures. These findings can inform interventions and policies aimed at promoting gender equality in family life. - 2026
Imitation in the eyes of others: Agency and communion in observed mimicry.
People automatically imitate each other, which is known to elicit feelings of affiliation. Previous research on mimicry has mainly studied dyadic interactions and thereby neglected that many social interactions are often observed by others. This raises the question of how observers perceive individuals who mimic or are mimicked. Based on previous research, we formulated two competing hypotheses about how third-party observers perceive people who initiate actions and people who mimic the actions along the Big Two dimensions (i.e., agency vs. communion). We tested these hypotheses against each other in eight experiments. The results strongly support the “Agency Hypothesis” according to which people who initiate actions are perceived as more agentic than people who mimic the actions. Our experiments also find some support for the “Communion Hypothesis” indicating that people who mimic actions are perceived as more communal than people who initiate the actions. Interestingly, support for the Agency Hypothesis was very robust, whereas the effect on perceived communion was more variable and dependent on the stimuli used. When investigating downstream consequences of the link between observed mimicry and ascriptions along the Big Two dimensions, we find that both ascribed agency and communion predict donation behavior. - 2023-05-19

Opinia prawna dotycząca przedstawionego przez Prezydium Sejmu projektu uchwały w sprawie zmiany Regulaminu Sejmu Rzeczypospolitej Polskiej (druk nr 389)
The legal analysis deals with the assessment of the Presidium’s draft resolution of the Sejm of the Republic of Poland amending the Standing Orders of the Sejm and aimed at enhancing the efficiency of legislative and pre-legislative procedures. The draft resolution envisages the introduction of a mandatory regulatory impact assessment (RIA) of bills tabled by deputies, as well as the obligation to conduct public consultations, with the objective of strengthening transparency and fostering social participation in the legislative procedure. The proposed amendments aim as well to limit the use of the so-called fast-track legislative procedures in order to improve the quality of the law that is enacted and prevent potential procedural abuses. The proposed amendments meet the commitments arising from the so-called milestones of the recovery and resilience plan adopted by the European Union; their implementation was not completed within the prescribed timeline. The author’s assessment of the compliance of the draft resolution with the principles of sound legislation and the provisions of the Constitution of the Republic of Poland is unequivocally positive. Nevertheless, he underscores that it is necessary to clarify the provisions establishing the option of not conducting public consultations and the provisions laying down the conditions for expediting the legislative procedure, so that potential interpretative ambiguities and the risk of using the ambiguities instrumentally can be avoided. - 2025-07-19
Status układów zbiorowych pracy według systemowej wykładni Konstytucji RP
This article presents a constitutional perspective of collective labour agreements within the system of sources of law. The author particularly focuses on highlighting the constitutional-law nature of collective labour agreements. Additionally, the article points out doctrinal differences in the perception of the legal character of collective labor agreements. The author argues that collective labor agreements should be regarded as normative acts sui generis, which are not issued within the framework of legislative competence, but remain one of the fundamental institutions of collective labor law. According to the author, collective labour agreements do not constitute sources of law as defined in Chapter II of the Constitution, a position that is also supported by a substantial part of legal doctrine and the case law of the Supreme Court. Moreover, they do not have the character of being universally or internally binding, nor do they take the so-called “mixed” form. The publication also emphasizes that the compliance of collective labour agreements with the law should be determined by the competent common court, rather than the Constitutional Tribunal of Poland or the Supreme Administrative Court.

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.
