The transition to middle/junior high school is associated with declines in students’ academic performance, especially among low‐income, urban youth. Developmental psychologists posit such declines are due to a poor fit between the needs of early adolescents—industry, identity, and autonomy—and the environment of their new schools. Extracurricular participation during these years may act as a buffer for youth, providing a setting for development outside the classroom. The current study examines participation within and across activity settings among low‐income, urban youth in New York City over this transition. Using the Adolescent Pathways Project data, this study explores how such participation relates to course performance. We find that a large percentage of youth are minimally or uninvolved in extracurricular activities during these years; that participation varies within youth across time; and that the association between participation and course performance varies by activity setting. Youth who participate frequently in community or athletic settings or have high participation in two or more settings are found to have higher GPAs in the year in which they participate and youth who participate frequently in the religious setting are found to have lower GPAs. High participation in more than two settings may be detrimental.  相似文献

This study examined, in a sample of recently immigrated Hispanic adolescents in Miami and Los Angeles, the extent to which bicultural identity integration (BII; involving the ability to synthesise one's heritage and receiving cultural streams and to identify as a member of both cultures) is best understood as a developmental construct that changes over time or as an individual‐difference construct that is largely stable over time. We were also interested in the extent to which these trajectories predicted mental health and family functioning. Recent‐immigrant 9th graders (N = 302) were assessed 6 times from 9th to 12th grade. Latent class growth analyses using the first 5 timepoints identified 2 trajectory classes—one with lower BII scores over time and another with higher BII scores over time. Higher heritage and US identity at baseline predicted membership in the higher BII class. At the 6th study timepoint, lower BII adolescents reported significantly poorer self‐esteem, optimism, prosocial behaviour and family relationships compared with their higher BII counterparts. These findings are discussed in terms of further research on the over‐time trajectory of biculturalism, and on the need to develop interventions to promote BII as a way of facilitating well‐being and positive family functioning.  相似文献

This article reports a short-term longitudinal study focusing on popularity and social acceptance as predictors of academic engagement for a sample of 342 adolescents (approximate average age of 14). These youths were followed for 4 consecutive semesters. Popularity, social acceptance, and aggression were assessed with a peer nomination inventory, and data on academic engagement were obtained from school records. For adolescents who were highly aggressive, increases in popularity were associated with increases in unexplained absences and decreases in grade point average. Conversely, changes in social acceptance were not predictive of changes in grade point average or unexplained absences. These results highlight the importance of multidimensional conceptualizations of social standing for research on school adjustment during adolescence and emphasize the potential risks associated with popularity.  相似文献

Naming a picture of a dog primes the subsequent naming of a picture of a dog (repetition priming) and interferes with the subsequent naming of a picture of a cat (semantic interference). Behavioral studies suggest that these effects derive from persistent changes in the way that words are activated and selected for production, and some have claimed that the findings are only understandable by positing a competitive mechanism for lexical selection. We present a simple model of lexical retrieval in speech production that applies error-driven learning to its lexical activation network. This model naturally produces repetition priming and semantic interference effects. It predicts the major findings from several published experiments, demonstrating that these effects may arise from incremental learning. Furthermore, analysis of the model suggests that competition during lexical selection is not necessary for semantic interference if the learning process is itself competitive.  相似文献

Medical students and faculty explore the medical humanities for diverse reasons: as a medium for self-reflection, a means to cultivate professionalism and humanism, and a way to gain an appreciation for the broader contexts in which illness and health occur. One important area for development is increasing the exposure of learners and clinicians of various levels of training to the medical humanities and to role models in the field. Student-led programs in the medical humanities at the American Medical Student Association (AMSA) address these needs by offering unique opportunities for learning and sharing experiences. AMSA programs connect physicians-in-training using technology to create virtual communication and learning opportunities. These include monthly book discussion webinars, the Writers' Institute and the Medical Humanities Scholars Program (MHSP).  相似文献

Abstract

The effect of affective group bibliotherapy (GB) was compared to affective group therapy (GT) on patients’ functioning in therapy and their session impression. Three small groups totaling twenty–five in–patients in a hospital in Israel participated in the study. Clients concurrently participated in both group types, undergoing three sessions in each condition. In–therapy behaviors were assessed through the Client Behavior System (CBS; Hill &; O’Brien, 1999). Results indicated that in the GB condition compared to the GT condition, clients showed less resistance, used simple responses less frequently, and expressed greater affective exploration. The Session Evaluation Questionnaire (SEQ; Stiles et al., 1994) was used to measure clients’ impressions of the sessions. Results indicated that patients evaluated the two treatment conditions equally. Overall, the results support earlier findings, suggesting that affective bibliotherapy can be an effective method of treatment.  相似文献

Building on the theory of reasoned action (I. Ajzen & M. Fishbein, 1973, 1980; M. Fishbein & I. Ajzen, 1975) and expectancy theory, the authors examined the mediating role of alcohol expectancies in adolescent drinking behaviors by testing whether alcohol expectancy outcomes and valuations (the extent to which these outcomes are perceived as good or bad) mediate the association between peer influences and lifetime alcohol use. Early adolescents (N = 904) from 2 public middle schools in western Michigan completed a battery of questionnaires. Overall, results showed that alcohol expectancies and valuations partially mediated the relations between peer influences (peer use and peer approval) and lifetime alcohol use. The findings suggest that associating with peers who are perceived as using alcohol and approving of drinking may influence adolescents’ alcohol expectancies. The authors briefly discuss future research directions and implications for prevention.  相似文献
