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

Property evaluations rarely occur in the absence of social context. However, no research has investigated how intergroup processes related to prejudice extend to concepts of property. In the present research, we propose that factors such as group status, prejudice and pressure to mask prejudiced attitudes affect how people value the property of racial ingroup and outgroup members. In Study 1, White American and Asian American participants were asked to appraise a hand‐painted mug that was ostensibly created by either a White or an Asian person. Asian participants demonstrated an ingroup bias. White participants showed an outgroup bias, but this effect was qualified. Specifically, among White participants, higher racism towards Asian Americans predicted higher valuations of mugs created by Asian people. Study 2 revealed that White Americans' prejudice towards Asian Americans predicted higher valuations of the mug created by an Asian person only when participants were highly concerned about conveying a non‐prejudiced personal image. Our results suggest that, ironically, prejudiced majority group members evaluate the property of minority group members whom they dislike more favourably. The current findings provide a foundation for melding intergroup relations research with research on property and ownership.  相似文献

Test anxiety (TA) is a prevalent issue among students that can result in deleterious consequences, such as underachievement. However, a contemporary measure that has been validated for use with Australian students seems to be lacking. This study, therefore, investigated the suitability of the German Test Anxiety Inventory (TAI‐G) for use with Australian university students. While the original TAI‐G contains 30 items and was designed to measure four factors (worry, emotionality, interference, and lack of confidence), differing factorial models have been supported in the literature using either the original or a shortened 17‐item version of the measure. These differing TAI‐G models were tested and compared in the current study via confirmatory factor analysis using 224 Australian university students. As expected, results supported the superior fit of the 17‐item four‐factor model. Additionally, the convergent validity of the measure was supported since measures of self‐esteem, self‐efficacy, and general anxiety were all found to correlate significantly with the TAI‐G in the hypothesised directions. Finally, the finding that all of the TAI‐G subscales had acceptably high reliabilities led to the conclusion that the 17‐item TAI‐G is a valid and reliable measure of TA in an Australian university population.  相似文献
