Examination of adolescents' negative thoughts, depressive mood, and family environment. 总被引:2,自引:0,他引:2
The focus of this study was the relationship among adolescents' negative thoughts, depressive mood, and family environment. Three hundred eleven students (aged 16 and 17 years) in public and private schools served as subjects. They were administered the Family Environment Scale, the Automatic Thoughts Questionnaire, and the Beck Depression Inventory. Family cohesion was found to be related to the degree of negative thoughts and depressive mood of the adolescents, but perceived control within the family was not. 相似文献

Although the presentation of extraneous (i.e., irrelevant or unnecessary) information hinders learning, it is unclear whether and how layout and pacing influence this effect. In two experiments, participants learned how the heart functions using four different layouts: a diagram presented without unnecessary text (diagram only), with unnecessary text separated from the diagram (separated) or integrated into the diagram (integrated), or with separated unnecessary text and the instruction to integrate (integration instruction). In Experiment 1, study time was self‐paced for half of the participants and system paced for the other half. There were no effects of layout and of pacing on learning, although system pacing was more effortful than self‐pacing. In Experiment 2, which was system paced and employed eye tracking, the integrated condition showed worse learning outcomes than the separated condition. Moreover, in the integrated condition, participants made more integration attempts between the unnecessary text and the diagram than in the separated condition. 相似文献

Among executive functions (EFs), research has highlighted specific inhibition difficulties in preterm children. The present paper reviews and classifies the studies that assessed response inhibition and interference control abilities in preterm children and adolescents aged 3 to 16 years. Most behavioral studies agree on a developmental delay at early school age in inhibition abilities and a catch-up before adolescence, with lesser response inhibition difficulties at pre-adolescence. However, persisting interference control difficulties have been reported into early adulthood. These results are discussed, along with functional magnetic resonance imaging (fMRI) findings. Finally, this paper outlines methodological issues that need to be overcome in order to define the developmental trajectory of inhibition abilities in the preterm population. 相似文献

Another Test of Gender Differences in Assignments to Precarious Leadership Positions: Examining the Moderating Role of Ambivalent Sexism 下载免费PDF全文
Women face significant hurdles in the attainment of leadership positions. When they do attain them such positions tend to be riskier than those attained by men, a form of bias called glass cliff. This study investigates ambivalent sexism as an individual difference that influences the occurrence of glass cliff. Little research examines individual differences contributing to glass cliff. It is proposed that individuals with high hostile and benevolent sexism are more likely to perceive women to be suitable for leadership of a poorly‐performing organization and men to be suitable for leadership of a well‐performing organization. The sample of our experimental study consisted of 378 students who rated either a female or a male candidate under a poor or good performance condition. We tested our hypotheses using a moderated regression analysis. Both components of sexism impacted how individuals evaluated male and female leaders under different organizational performance conditions. Hostile sexism was the dimension that led to glass cliff. Benevolent sexism had an unexpected effect on leadership choice. The differences between the two types of sexism and the different role each type plays in preference for masculine and feminine leadership are discussed. Leader gender and perceiver's sexist attitudes influence evaluations for leadership positions. 相似文献

Using an empirical data set, we investigated variation in factor model parameters across a continuous moderator variable and demonstrated three modeling approaches: multiple-group mean and covariance structure (MGMCS) analyses, local structural equation modeling (LSEM), and moderated factor analysis (MFA). We focused on how to study variation in factor model parameters as a function of continuous variables such as age, socioeconomic status, ability levels, acculturation, and so forth. Specifically, we formalized the LSEM approach in detail as compared with previous work and investigated its statistical properties with an analytical derivation and a simulation study. We also provide code for the easy implementation of LSEM. The illustration of methods was based on cross-sectional cognitive ability data from individuals ranging in age from 4 to 23 years. Variations in factor loadings across age were examined with regard to the age differentiation hypothesis. LSEM and MFA converged with respect to the conclusions. When there was a broad age range within groups and varying relations between the indicator variables and the common factor across age, MGMCS produced distorted parameter estimates. We discuss the pros of LSEM compared with MFA and recommend using the two tools as complementary approaches for investigating moderation in factor model parameters. 相似文献

This review article argues that the critique of contemporary discourses about religious self-improvement offered by Craig Martin cannot bear the claim that the notion of individual religion must be dropped. On the one hand, comparable phenomena are not restricted to a Western present, and, on the other, they do not disprove the utility of heuristic terms like religion or individualisation. However, a religious semantic of entrepreneurship might be a phenomenon well worth further research. 相似文献

The paper describes the therapeutic relationship, specifically the countertransference enactments of the analyst whose own destructive impulses were inevitably mobilised in the treatment of a narcissistically disturbed patient. They are discussed in the light of other authors’ theoretical understanding of the described dynamics. The societal context of the analyst’s work is being discussed. 相似文献
