In a socio‐demographically diverse sample of 501 caregivers participating in a longitudinal birth cohort study during the childbearing years, we examined whether neighborhood collective efficacy moderated the association between maternal adverse childhood experience (ACEs) and marital conflict. Maternal ACEs were assessed via retrospective reports. Neighborhood collective efficacy was measured via maternal and paternal reports at 2 months, and maternal reports of marital conflict were collected at infant age 2 and 18 months. Multiple linear regression analyses revealed that maternal ACEs were associated with increased marital conflict. Neighborhood collective efficacy moderated the association between early maternal ACEs and marital conflict, such that mothers experiencing ACEs had lower levels of marital conflict when exposed to high levels of neighborhood collective efficacy. Results suggest that extra‐familial sources of social support and control, such as feelings of security, trust, order, and connectedness with others, may buffer the effects of early adversity on marital discord.  相似文献

The aim of this study was to assess the extent to which a sense of competence and beliefs about parental roles in mothers and fathers influence coparenting and child engagement in triadic interactions during the first 2 years of the child's life, after other influential variables such as marital satisfaction and postpartum depression have been controlled for. The sample constituted 69 mother–father–infant families, whose sense of competence, beliefs in parental roles, postpartum depression, and marital satisfaction were assessed in our laboratory at 3, 9, and 18 months with self‐reported questionnaires. Coparenting support and conflict and child engagement were assessed with the Lausanne Trilogue Play. Results show that (i) predictors of coparenting and child engagement are not the same at each time point; (ii) a sense of competence in mothers is positively linked with coparenting support, particularly at 3 months, whereas in fathers, it is negatively linked with support, particularly at 18 months; (iii) discrepancies between mothers and fathers in beliefs about the importance of the mother's role is the main predictor of coparenting conflict at 18 months; and (iv) paternal beliefs about the importance of the father's and mother's roles are the main predictor of child engagement at 18 months.

In contrast to mean‐level comparisons, age group differences in personality trait variance have received only passing research interest. This may seem surprising because individual differences in personality characteristics are exactly what most of personality psychology is about. Because different proposed mechanisms of personality development may entail either increases or decreases in variance over time, the current study is exploratory in nature. Age differences in variance were tested by comparing the standard deviations of the five‐factor model domain and facet scales across two age groups (20 to 30 years old versus 50 to 60 years old). Samples from three cultures (Estonia, the Czech Republic and Russia) were employed, and two methods (self‐reports and informant‐reports) were used. The results showed modest convergence across samples and methods. Age group differences were significant for 11 of 150 facet‐level comparisons but never consistently for the same facets. No significant age group differences were observed for the five‐factor model domain variance. Therefore, there is little evidence for individual differences in personality characteristics being systematically smaller or larger in older as opposed to younger people. We discuss the implications of these findings for understanding personality development. Copyright © 2015 European Association of Personality Psychology  相似文献

Abstract The main objective of this study is to test the effects over time of three role stress variables (role conflict, role ambiguity and role overload) on the three burnout dimensions (emotional exhaustion, depersonalization and personal accomplishment). Based on theoretical models on burnout and on meta-analytical research, it is hypothesized that the three role stress variables will predict changes over time in emotional exhaustion and depersonalization, but not in personal accomplishment. The results obtained by means of hierarchical regression analysis partially support the hypothesis. The three role stress variables predict emotional exhaustion over time. Role conflict and role overload predict depersonalization over time. Finally, contrary to expectations, role ambiguity predicts personal accomplishment over time.  相似文献

It would be possible to be affirmed that the most of the educational goals that modernity assumes, they settled down from the Renaissance. The postmodern age, in its critic to the modern period, demands the recovery of some losses. At the time of fast changes as it happens in the Renaissance, the Humanism originates a fruitful debate. According to the authors protagonists, the controversy became a dialogue plenty of common questions to which we find in the contemporary discussion. The reflection on the thought of one of the most representative and well-known authors, Comenio, it serves to think on the encounter of traditions in Philosophy of Education. He is a thinker who supplies the basis for his educational practice on a Philosophy of education and projects a reform to confront some problems that in the essential are repeated today.   相似文献

Men's discourse about the paternal role is changing significantly. Despite the fact that men still perceive themselves as being responsible for the family's economical protection and the children's discipline, they face increasing demands for more involvement in childcare. From this perspective, this work analyzes the traditional view of gender roles and the perception of inequality in a sample of 95 employed fathers, as well as the various levels of satisfaction with other life roles and their relevance as a function of some gender and sociodemographic variables. The results show that men do not maintain a very traditional gender ideology with regard to role distribution and they still consider the paternal role and feelings as the most important thing in their lives. However, the couple relationship gives them the most satisfaction. Level of traditionalism and age were the two significant predicting variables of perception of inequality of men and women.  相似文献

Recently, several studies have been conducted to investigate the top-down adjustments made after incongruent trials during conflict tasks. In the present study, we investigated conflict monitoring with different types of conflict. In a modified version of the flanker task, a distinction was made between stimulus—stimulus conflict and stimulus—response conflict. Six colors were mapped to three responses in order to exclude all sequences in which a relevant or an irrelevant stimulus- or response-related feature was repeated from trialn−1 to trialn. An analysis of the effect of the congruency of the previous trial demonstrated that conflict adaptation was present. The stimulus congruency effect was reduced after both a stimulus-incongruent trial and a response-incongruent trial. The response congruency effect did not vary as a function of previous congruency. These findings are discussed in relation to the distinction between conflict detection and conflict regulation.  相似文献

This paper is devoted to the study of some subvarieties of the variety Qof Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Qis far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q 3 and we construct the lattice of subvarieties (Q 3 ) of the variety Q 3 .  相似文献

Semantic priming between words is reduced or eliminated if a low-level task such as letter search is performed on the prime word (the prime task effect), a finding used to question the automaticity of semantic processing of words. This idea is critically examined in 3 experiments with a new design that allows the search target to occur both inside and outside the prime word. The new design produces the prime task effect (Experiment 1) but shows semantic negative priming when the target letter occurs outside the prime word (Experiments 2 and 3). It is proposed that semantic activation and priming are dissociable and that inhibition and word-based grouping are responsible for reduction of semantic priming in the prime task effect.  相似文献
