The self-reported violent experiences of adolescents living in a public-subsidized urban high-rise building were examined. This effort was part of an interdisciplinary, community-university collaboration program called the HOME (High-rise On-site Multifamily Environments) Family Support Project. A survey of violent experiences and a one-on-one structured interview were conducted with 20 adolescent residents. Results of the quantitative and qualitative analyses revealed high degrees of exposure to violence among these adolescents, concerns for their personal safety, as well as insights into what they believe adults could and should be doing to address increasing levels of community violence. The implications of these results for conducting ecologically valid research on sensitive issues with adolescents and for family support program planning are discussed.  相似文献

The authors examined age differences in perceived coping resources and satisfaction with life across 3 older-adult age groups (45-64, 65-74, and 75 years and older). The 98 participants represented healthy, socially active, community-residing adults. Group comparisons were made on 12 individual coping scales, and an overall coping resource effectiveness score was computed. No significant differences were found for 11 of the coping resources or for overall coping resource effectiveness. Similar consistencies in life satisfaction were found across the 3 age groups. The findings indicate that (a) for healthy adults, the oldest old cope at least as effectively as their younger counterparts, despite their likelihood of encountering increased levels of stress; and (b) psychologically, old age may be viewed as a time of resilience and fortitude.  相似文献

Cross-correlation and most other longitudinal analyses assume that the association between 2 variables is stationary. Thus, a sample of occasions of measurement is expected to be representative of the association between variables regardless of the time of onset or number of occasions in the sample. The authors propose a method to analyze the association between 2 variables when the assumption of stationarity may not be warranted. The method results in estimates of both the strength of peak association and the time lag when the peak association occurred for a range of starting values of elapsed time from the beginning of an experiment.  相似文献

Transfer-appropriate processing (TAP), as applied to implicit memory, has tended to emphasize general forms of processing (e.g., perceptual or conceptual processing). In the present studies, the TAP principle was employed in a more specific manner in order to more precisely assess the relations between the processing engaged during first exposure and that engaged during second exposure to items. Thirteen experiments used a two-phase, cross-task design in which participants engaged in different combinations of seven specific intentional tasks between Phase 1 and Phase 2. Maximum repetition priming was found when tasks were the same in Phases 1 and 2. When Phase 1 and Phase 2 tasks differed, there were lesser, or no, repetition priming effects, depending on the particular combination of tasks. The results demonstrate the importance of the specific intentional processes engaged during repetition priming and the potential heuristic value of TAP, as a principle and methodology, for exploring the organization of memory and related process models.  相似文献

Two experiments with the Stroop paradigm were conducted to investigate the role of phonological codes in access to the meaning of Chinese characters. Subjects named the ink color of viewed characters or color patches. Key items were color characters, their homophones with the same tone, homophones with different tones, and semantic associates. Apart from finding the usual Stroop interference effect, homophones produced significant interference in the incongruent condition, provided that they had the same tone as the color characters. The interference effect from homophones, however, was significantly smaller than that from color characters. Semantic associates generated an interference effect in the incongruent condition, an effect of the same magnitude as the effect from the same-tone homophones. Finally, in the congruent conditions, all the key items yielded facilitations compared to neutral controls, though the facilitation from color characters was larger than the facilitations from other types of characters. These findings suggest that phonological codes in Chinese are activated obligatorily and provide early sources of constraint in access to meaning.  相似文献

Previous studies have found that subjects diagnosed with verbal auditory agnosia (VAA) from bilateral brain lesions may experience difficulties at the prephonemic level of acoustic processing. In this case study, we administered a series of speech and nonspeech discrimination tests to an individual with unilateral VAA as a result of left-temporal-lobe damage. The results indicated that the subject's ability to perceive steady-state acoustic stimuli was relatively intact but his ability to perceive dynamic stimuli was drastically reduced. We conclude that this particular aspect of acoustic processing may be a major contributing factor that disables speech perception in subjects with unilateral VAA.  相似文献

The purpose of the present study was to examine the potential efficacy, patient acceptability, and feasibility of a novel, cognitive-behavioral therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD) who have been stabilized on medications but still show clinically significant symptoms. Thirty-one adults with ADHD and stable psychopharmacology for ADHD were randomized to CBT plus continued psychopharmacology or continued psychopharmacology alone. Assessments included ADHD severity and associated anxiety and depression rated by an independent evaluator (IE) and by self-report. At the outcome assessment, those who were randomized to CBT had lower IE-rated ADHD symptoms (p < .01) and global severity (p < .002), as well as self-reported ADHD symptoms (p < .0001) than those randomized to continued psychopharmacology alone. Those in the CBT group also had lower IE-rated and self-report anxiety (p's < .04), lower IE-rated depression (p < .01), and a trend to have lower self-reported depression (p = .06). CBT continued to show superiority over continued psychopharmacology alone when statistically controlling levels of depression in analyses of core ADHD symptoms. There were significantly more treatment responders among patients who received CBT (56%) compared to those who did not (13%) (p < .02). These data support the hypothesis that CBT for adults with ADHD with residual symptoms is a feasible, acceptable, and potentially efficacious next-step treatment approach, worthy of further testing.  相似文献
