This qualitative study explored environmental factors that influence adolescents’ responses to problem situations involving peers. Interviews were conducted with 106 middle school students (97% African American) from an urban school system. Participants were asked to describe factors that would make it easier and those that would make it more difficult for adolescents to make specific responses to problem situations. Two types of responses were presented: nonviolent responses identified as effective in a previous study, and fighting responses. Qualitative analysis identified 24 themes representing family, peer, school, and neighborhood and broader social factors that were related to both nonviolent behavior and fighting. The identification of environmental influences on fighting and nonviolent responses has important implications for efforts to reduce aggression and promote effective nonviolent responses to problem situations encountered by adolescents.  相似文献

Disruption of normal emotional experience is central to the phenomenology of depression. Twenty-three depressed outpatients and 23 control subjects performed a computerized decision-making task, during which affective ratings were assessed online to identify various dimensions of emotional experience. We sought to contrast regret (the comparison of the outcomes of selected and nonselected options) with the general negative appraisal of task events. The experience of regret was reduced in depressed patients, an effect that was particularly related to self-reported apathy scores. In an exploratory analysis, we observed that females had a general downward shift in their ratings, as compared with males, but disappointment and regret effects were of similar magnitude. The possible contribution of the orbitofrontal cortex to the phenomenology of regret is discussed.

This study discusses a case of aphasia after dominant thalamic lesion, a hemorrhagic infarction. Unlike other such cases, both repeated standardized assessment and postmortem verification were available. The patient was assessed at 3 weeks and again at 9 weeks postonset. The aphasia demonstrated the syndrome common to dominant thalamic hemorrhage: fluent but paraphasic output sometimes deteriorating to jargon, comprehension less impaired than this type of output usually indicates, and the least impairment in repetition. As sometimes reported in previous cases, semantic paraphasias were more common than phonemic paraphasias. The lesion was located in the dorsal aspect of the lateral nucleus, but it extended into the pulvinar, including the anterior superior lateral aspect which has been implicated in language by previous studies. Thus, data from this case are consistent with an involvement of the dominant pulvinar in language and suggest that this role involves the semantic aspects of language.  相似文献
