Using implicit tests, older adults have been found to retain conceptual knowledge of previously seen task-irrelevant information. While younger adults typically do not show the same effect, evidence from one study [Gopie, N., Craik, F. I. M., & Hasher, L. (2011). A double dissociation of implicit and explicit memory in younger and older adults. Psychological Science, 22, 634–640. doi:10.1177/0956797611403321] suggests otherwise. In that study, young adults showed greater explicit than implicit memory for previous distractors on a word fragment completion task. This was interpreted as evidence for maintaining access to previous conceptual knowledge of the distractors. Here, we report two failures to replicate that original finding, followed by a third study designed to test directly whether young adults use conceptual-level information that was previously irrelevant. Our findings agree with others that young adults show weak to no evidence of conceptual knowledge of previously irrelevant information. 相似文献

In the present study, the predictors and outcomes associated with the trajectories of peer rejection were examined in a longitudinal sample of Italian children (338 boys, 269 girls) ages 10 to 14 years. Follow-up assessments included 60% of the original sample at age 16–17. Low, medium, and high rejection trajectory groups were identified using growth mixture models. Consistent with previous studies, we found that (a) being less prosocial and more physically aggressive at age 10 was characteristic of those children with the high rejection trajectory; (b) being less attractive was related to higher peer rejection from age 10 to 14; and (c) boys with a high rejection trajectory showed high levels of delinquency and anxiety-depression and low levels of academic aspiration at age 16–17, whereas girls with a high rejection trajectory showed low levels of academic aspiration and social competence at age 16–17. Our findings indicate the detrimental consequences of peer rejection on children’s development and adjustment and shed light on the mechanisms that contribute to maintaining or worsening (e.g., being attractive, prosocial, and aggressive) a child’s negative status (e.g., being rejected) within his or her peer group over time. 相似文献

Differing profiles of developmental experiences across types of organized youth activities 总被引:1,自引:0,他引:1
This study inventoried the types of developmental and negative experiences that youth encounter in different categories of extracurricular and community-based organized activities. A representative sample of 2,280 11th graders from 19 diverse high schools responded to a computer-administered protocol. Youth in faith-based activities reported higher rates of experiences related to identity, emotional regulation, and interpersonal development in comparison with other activities. Sports and arts programs stood out as providing more experiences related to development of initiative, although sports were also related to high stress. Service activities were associated with experiences related to development of teamwork, positive relationships, and social capital. Youth reported all of these positive developmental experiences to occur significantly more often in youth programs than during school classes. 相似文献
