Children who experience parentification may have trouble performing developmental tasks due to being overwhelmed by their family caregiving roles and responsibilities. Past studies have found that parentification is negatively associated with academic achievement. However, most of these studies are limited in that they are retrospective and examine the association but not the mechanisms shaping them. The aim of the study was to explore to what extent diverse types of parentification relate to academic achievement and to what extent these relations are (...) mediated by self-reported quality of life among adolescents. The study sample was composed of Polish early adolescents. Types of parentification were measured with the Parentification Questionnaire for Youth, and quality of life was assessed with KidScreen27. School achievement was measured based on mean semester grade. We explored the associations among study variables and performed six mediation models in the planned analyses. Overall, bivariate relations were significant in a theoretically expected way, although the effect sizes for these associations were rather small. In the mediation analyses, the results showed that four of the six models were not significant. Different from previous studies, instrumental parentification was positively related to school achievement. Additionally, this positive association was mediated by adolescents’ general quality of life. Taken together, the findings were similar and different from the empirical literature base on types of parentification and select outcomes. (shrink)

The aim of the study was to examine the role of self-esteem in resisting the influence of materialistic goals of four social role models in adolescents. Previous studies showed a negative correlation between the psychological health of teens and striving for materialistic goals, one of the main sources is the social modeling of materialism. Two studies were carried out. The first, correlational study, was conducted on target teens and their mothers, fathers, and peers of their choice. It examined if self-esteem (...) is a moderator of the relationship between the materialism of social role models and the materialism of teens. The second, experimental study, was conducted on target teens only. It examined how boosting the self-esteem of teens and activating materialism of social role models may affect the materialism of teens. Study 1 showed a significant interaction effect of self-esteem and the materialism of peers on the materialism of teens. The interaction effects of self-esteem and other role models were not significant. Study 2 showed that elevated self-esteem lowered the influence of the materialism of peers on the materialism of teens. The results were not significant when other role models were analyzed. The results obtained in the presented studies indicate that the self-esteem of teens may have an important role in resisting the influence of materialism role models of peers. Practical implications of the studies for the psychological health of teens are also discussed. (shrink)

Artykuł przybliża budowę synaptycznej strefy aktywnej oraz omawia funkcje zlokalizowanych tam białek, bez których przekaźnictwo w układzie nerwowym byłoby niemożliwe. Autorzy zwrócili szczególną uwagę na fizjologiczny aspekt działania omawianych substancji, a także neurologiczne oraz behawioralne konsekwencje usunięcia kodujących je genów z puli genowej organizmu. Zamieszczone ryciny schematycznie ukazują obraz synapsy oraz tworzone przez opisane białka wiązania chemiczne w synaptycznej strefie aktywnej.
