Despite the growth of youth mentoring programs in recent years, key questions remain regarding the relative importance of making matches on the basis of shared racial background. Both sides of the argument regarding racial matching are presented, followed by a comparison of the effects of same‐ vs. cross‐race matches involving minority youth (N= 476). Minority adolescents were less likely to report initiating alcohol when placed in cross‐race matches. In addition, minority boys in same‐race matches reported smaller decrements in scholastic competence and self‐worth than did minority boys in cross‐race matches. Minority girls in same‐race matches reported smaller decrements in school value and self‐worth than did minority girls in cross‐race matches. Youth, parent, and caseworker impressions of the 2 relationship types largely converged, but the few impressions that differed tended to favor cross‐race matches. The methodological limitations and implications of this study are discussed.  相似文献

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.  相似文献

The effect of youth homelessness on age of entry into prostitution was tested, controlling for other known covariates using a multivariate model. Women (N = 96) who self-identified as having engaged in prostitution completed cross-sectional standardized questionnaires (Mage = 42.6, SD = 9.18; 62% African American). Women with a history of youth homelessness entered prostitution nearly 8 years earlier than their peers without this history (at 18 vs. 25 years old). Lack of a high school degree or equivalent also predicted an earlier age of entry (at 20 vs. 28 years old). Findings highlight the poverty dynamics that underlie the relationship between early entry into prostitution and homelessness. Young women, living on the street or in shelters, with limited education and employment opportunities, are at high risk of entering prostitution when they are barely out of adolescence. Future research will be better able to design age-specific prevention strategies.  相似文献

This special issue of the British Journal of Psychology brings together cutting edge research on a range of topics in visual working memory (VWM). In this commentary, we attempt to summarize common themes in current VWM research exemplified in this issue. The articles include several reviews of important topics as well as empirical papers covering three main themes. The first concerns the nature of mental representations of memoranda in the commonly used delayed estimation task, where both fine‐grained and broad categorical details appear to be represented, and their susceptibility to interference. The second concerns interactions between VWM representations, both those that produce individuation of representations and those that create an overarching ensemble structure. Finally, the third main topic concerns the use of VWM during visual search and in the learning of repeated configurations in search displays. The work presented here, and other work in the field, points to a rich interplay between representations in VWM but also between VWM and information in long‐term memory. Opportunities for further investigation are highlighted throughout.  相似文献

This paper explores Calkins’ absolute idealism and its ramifications for libertarian free will. Calkins’ metaphysics is a version of absolute idealism, according to which the absolute is a person who has everything else as either a part or an aspect. Three different arguments for the conclusion that Calkins’ metaphysics is incompatible with libertarian freewill are formulated and critically assessed. Finally, I assess the extent to which these arguments are independent of each other.  相似文献

We applied the moral dissonance reduction framework, used to explain the maintenance of a positive self-concept in dishonest behavior, to understand self-justification of prejudice. Participants identified ambiguously negative intergroup behaviors, then evaluated those behaviors when performed by others and themselves. As predicted by moral dissonance reduction, participants were less critical of their own behavior when considering others’ behaviors before their own. In a third study directly comparing prejudiced and dishonest behavior, participants’ responses showed the greatest self-justification in the initial question about their behavior regardless of the content of the question, whereas subsequent questions showed more stability, consistent with the idea that participants adjusted their initial self-reports to avoid damage to their self-concepts.  相似文献

Faces are adaptively coded relative to visual norms that are updated by experience, and this adaptive coding is linked to face recognition ability. Here we investigated whether adaptive coding of faces is disrupted in individuals (adolescents and adults) who experience face recognition difficulties following visual deprivation from congenital cataracts in infancy. We measured adaptive coding using face identity aftereffects, where smaller aftereffects indicate less adaptive updating of face‐coding mechanisms by experience. We also examined whether the aftereffects increase with adaptor identity strength, consistent with norm‐based coding of identity, as in typical populations, or whether they show a different pattern indicating some more fundamental disruption of face‐coding mechanisms. Cataract‐reversal patients showed significantly smaller face identity aftereffects than did controls (Experiments 1 and 2). However, their aftereffects increased significantly with adaptor strength, consistent with norm‐based coding (Experiment 2). Thus we found reduced adaptability but no fundamental disruption of norm‐based face‐coding mechanisms in cataract‐reversal patients. Our results suggest that early visual experience is important for the normal development of adaptive face‐coding mechanisms.  相似文献
