Adolescence is a critical developmental period marked by an increase in risk behaviors, including nonsuicidal self‐injury (NSSI). Heightened reward‐related brain activation and relatively limited recruitment of prefrontal regions contribute to the initiation of risky behaviors in adolescence. However, neural reward processing has not been examined among adolescents who are at risk for future engagement for NSSI specifically, but who have yet to actually engage in this behavior. In the current fMRI study (N = 71), we hypothesized that altered reward processing would be associated with adolescents' thoughts of NSSI. Results showed that NSSI youth exhibited heightened activation in the bilateral putamen in response to a monetary reward. This pattern of findings suggests that heightened neural sensitivity to reward is associated with thoughts of NSSI in early adolescence. Implications for prevention are discussed. 相似文献

This study examined age differences in collaborative inhibition and the role of inter‐subjectivity, collective information sampling (CIS) and collaborative inhibition for the collaborative recall of shared and unshared information in groups of 7‐ and 9‐year‐old children. Three‐hundred and thirteen 7‐ and 9‐year‐old children recalled memorized wordlists either in real or nominal groups of three. All group members either recalled the same items, or each group member was given some unique items. Nine‐year‐olds, but not 7‐year‐olds, recalled significantly more items in nominal than real groups, a phenomenon called collaborative inhibition. Groups whose interactions were characterized by higher numbers of inter‐subjective exchanges recalled fewer words than groups low in inter‐subjectivity. In both age groups, a higher proportion of shared compared with unshared information was recalled consistent with processes of CIS. However, 7‐year‐olds recalled more unshared items than predicted, suggesting that collaborative inhibition additionally contributes to the recall of shared and unshared items. 相似文献

ABSTRACTIn philosophical analyses of the value of sport, a relatively unheralded feature is the opportunity that sport offers for admiration. While we readily salute many of the things that people admire (the amazing catch, the sensational comeback), we do not sufficiently appreciate that admiration itself is a positive good that is beneficial to the admirer. At a time when much in the world around us seems distinctly unadmirable and when admiration itself is often dismissed as naïve, athletic achievements and the qualities that propel them present palpable counter-evidence to our darker conclusions. Shining a spotlight on sports’ displays of human beings doing difficult things can pay healthy dividends, as admiration fuels aspiration.The paper proceeds in four stages. It first explains what admiration is and then identifies the kinds of things that sport distinctly offers, to admire. The heart of it demonstrates the value of athletic admiration, tracing how this contributes to a flourishing life in three principal ways: through the role-modeling that it offers, the action that it encourages and the feelings that it fosters. Finally, the paper considers four possible objections, which serves both to clarify and to fortify its central contention. 相似文献
