The Polish Catholic Church’s perception of the processes of EU integration and Europeanisation in the context of traditional norms and values

The Catholic Church has historically played a significant role in the sociocultural and political life of Poland. Its activity was particularly evident and significant during the process of political transformation. Since 1989, however, the sociopolitical conditions have remarkably changed, thereby placing the church in a new, challenging context. Poland’s post-1989 political aspirations (opening to the West in particular) have come to the fore of the public debate, in which the church has actively participated. In this article I aim to analyse the church’s position on the process of EU integration and the Europeanisation of Polish law and culture. The main questions concern the direction of argumentation used by the church’s internal wings and the politicisation of the discourse on the axiological shape of Polish culture and tradition. My analysis embraces the debate surrounding the process of European integration, with special consideration of the church’s internal divisions (between the ‘centre-right’ and ‘radical-right’ in particular) and ideological discrepancies concerning the very idea of integration and the debates on the draft Constitution of the European Union (Constitutional Treaty) and the Charter of Fundamental Rights and Freedoms of the European Union.     

Characteristics of Athletes’ Approach to the Question of Physical Health and Health Behaviors: Do Athletes Lead Healthy Lifestyles?

Athletes are people for whom physical health is a key value. Health promoting behaviors are an integral part of athletes’ success. The aim of this article is to identify health criteria and health-related behaviors among athletes and their determinants in terms of temperament and personality features. The concept of healthy lifestyle as understood by athletes and their most important health criteria were defined. Neuroticism and extraversion correlated with and were significant predictors of health behaviors; there were no significant relationships between health-promoting behaviors and temperament. Four groups of athletes, each characterized by a different approach to health, were identified. These groups were described with respect to various personality and temperamental determinants. Knowledge about the above-mentioned aspects of athletes’ performance can assist sport psychologists in providing athletes with more personalized support.     

Time Points: A Gestural Study of the Development of Space–Time Mappings

Human languages typically employ a variety of spatial metaphors for time (e.g., “I'm looking forward to the weekend”). The metaphorical grounding of time in space is also evident in gesture. The gestures that are performed when talking about time bolster the view that people sometimes think about regions of time as if they were locations in space. However, almost nothing is known about the development of metaphorical gestures for time, despite keen interest in the origins of space–time metaphors. In this study, we examined the gestures that English‐speaking 6‐to‐7‐year‐olds, 9‐to‐11‐year‐olds, 13‐to‐15‐year‐olds, and adults produced when talking about time. Participants were asked to explain the difference between pairs of temporal adverbs (e.g., “tomorrow” versus “yesterday”) and to use their hands while doing so. There was a gradual increase across age groups in the propensity to produce spatial metaphorical gestures when talking about time. However, even a substantial majority of 6‐to‐7‐year‐old children produced a spatial gesture on at least one occasion. Overall, participants produced fewer gestures in the sagittal (front‐back) axis than in the lateral (left‐right) axis, and this was particularly true for the youngest children and adolescents. Gestures that were incongruent with the prevailing norms of space–time mappings among English speakers (leftward and backward for past; rightward and forward for future) gradually decreased with increasing age. This was true for both the lateral and sagittal axis. This study highlights the importance of metaphoricity in children's understanding of time. It also suggests that, by 6 to 7 years of age, culturally determined representations of time have a strong influence on children's spatial metaphorical gestures.     

Collective Narcissism and Intergroup Hostility: The Dark Side of ‘In‐Group Love’

This paper reviews current research on intergroup consequences of collective narcissism – an emotional investment in an unrealistic belief in exaggerated greatness of an in‐group. Integrating findings of the psychology of intergroup relations with findings regarding psychological outcomes of individual narcissism, the collective narcissism construct addresses the relationship between ‘in‐group love’ and ‘out‐group hate’. Differentiating between narcissistic and genuine positive group regard uncovers the potential of genuine ‘in‐group’ love to motivate positive out‐group attitudes and intergroup tolerance. Collective narcissism is also shown to be the aspects of positive group attachment that inspires defensive and retaliatory intergroup hostility under perceived threat. Narcissistic idealization of an in‐group is contingent on external validation and underlain by internal doubts. Collective narcissists are never fully satisfied with external acknowledgement of the in‐group and they are sensitive to anything that may undermine the in‐group’s exaggerated image.     

The role of similarity and dissimilarity focus in sequential judgments of physical attractiveness

The present results indicate that procedurally priming comparison focus can change the contrast effect in judgments of physical attractiveness (Kenrick & Gutierres, 1980). Participants were primed to search for similarities vs. differences between target and standard of comparison in a task using material irrelevant to the subsequent physical attractiveness judgment. Focusing participants on similarities testing produced the assimilation effect: evaluation of target and comparison standard as being similar. Focusing participants on dissimilarity testing produced the contrast effect: evaluating the target as different from the standard of comparison.     

Environmental enrichment protects against the effects of chronic stress on cognitive and morphological measures of hippocampal integrity

Chronic stress has detrimental effects on hippocampal integrity, while environmental enrichment (EE) has beneficial effects when initiated early in development. In this study, we investigated whether EE initiated in adulthood would mitigate chronic stress effects on cognitive function and hippocampal neuronal architecture, when EE started one week before chronic stress began, or two weeks after chronic stress onset. Adult male Sprague Dawley rats were chronically restrained (6h/d) or assigned as non-stressed controls and subdivided into EE or non-EE housing. After restraint ended, rats were tested on a radial arm water maze (RAWM) for 2-d to assess spatial learning and memory. The first study showed that when EE began prior to 3-weeks of chronic stress, EE attenuated chronic stress-induced impairments in acquisition, which corresponded with the prevention of chronic stress-induced reductions in CA3 apical dendritic length. A second study showed that when EE began 2-weeks after the onset of a 5-week stress regimen, EE blocked chronic stress-induced impairments in acquisition and retention at 1-h and 24-h delays. RAWM performance corresponded with CA3 apical dendritic complexity. Moreover, rats in EE housing (control or stress) exhibited similar corticosterone profiles across weeks, which differed from the muted corticosterone response to restraint by the chronically stressed pair-housed rats. These data support the interpretation that chronic stress and EE may act on similar mechanisms within the hippocampus, and that manipulation of these factors may yield new directions for optimizing brain integrity and resilience under chronic stress or stress related neuropsychological disorders in the adult.
