Bystander responses to public episodes of child abuse were surveyed among 269 self reported witnesses. Respondents completed an 80-item self-report questionnaire which inquired into a broad range of events, experiences, and behaviors surrounding naturally occurring incidents of perceived child abuse witnessed in public places. Almost one-half of the sample reported having witnessed at least one event of child abuse in public, but only one out of four witnesses acted to intervene. Data analyses identified 40 statistically significant variables across four categories: characteristics of the bystander, situation, victim, and perpetrator. Results were generally consistent with predictions and findings from previous research on bystander intervention, but a number of new and significant variables were identified that characterized intervention events. Direct and indirect forms of intervention were also distinguished. Implications of the findings are discussed, and educating people to intervene on behalf of abused children is proposed. 相似文献

Several theorists have suggested that impulsivity can be understood as a joint function of the behavioral approach (BAS) and behavioral inhibition systems (BIS). After resolving questions concerning the measurement of impulsivity and BAS, this study examined the relationships among risky health behaviors, impulsivity, BIS, and BAS. Utilizing a sample of undergraduates (N = 904), a structural model was tested in which BAS and BIS predicted impulsivity, which, in turn, predicted risky behavior. Fit indices were acceptable, but not good. A modified version of the model showed a statistically significant negative relationship between BAS and risky behaviors. However, the fit indices were not unequivocally supportive of the need to include that path. Overall, the data suggest that impulsivity is the joint result of countervailing motivational forces and that it partially or fully mediates the influence of BIS and BAS on risky health behavior. 相似文献

Twenty-three clinical trainees scored a standardized list of 150 Rorschach responses and were administered the EPPS. Ten directional hypotheses were advanced which predicted certain personality attributes of those making scoring errors in various determinant categories. Results showed significant differences between high and low error groups on scores on several EPPS scales, supporting four of the ten hypotheses. Scoring errors in the color, human movement, texture, and vista determinant categories were related to scores on the Exhibition, Affiliation, Autonomy, and Abasement scales, respectively. Implications of these results are discussed regarding the reliability of Rorschach interpretations. 相似文献

The internal consistency of the Test of Variables of Attention (TOVA) was examined in a cohort of 6- to 12-year-old children (N = 63) strictly diagnosed with ADHD. The internal consistency of errors of omission (OMM), errors of commission (COM), response time (RT), and response time variability (RTV) of different test conditions (stimulus infrequent condition [Q1 vs. Q2] and stimulus frequent condition [Q3 vs. Q4]) was assessed via correlation analyses. All TOVA index scores under investigation assessing its internal consistency exhibited statistically significant correlations. All correlations fell in the moderate-high range. 相似文献

The present study investigated whether developmental changes in cognitive control may underlie improvements of time-based prospective memory. Five-, 7-, 9-, and 11-year-olds (N = 166) completed a driving simulation task (ongoing task) in which they had to refuel their vehicle at specific points in time (PM task). The availability of cognitive control resources was experimentally manipulated by imposing a secondary task that required divided attention. Children completed the driving simulation task both in a full-attention condition and a divided-attention condition where they had to carry out a secondary task. Results revealed that older children performed better than younger children on the ongoing task and PM task. Children performed worse on the ongoing and PM tasks in the divided-attention condition compared to the full-attention condition. With respect to time monitoring in the final interval prior to the PM target, divided attention interacted with age such that older children’s time monitoring was more negatively affected by the secondary task compared to younger children. Results are discussed in terms of developmental shifts from reactive to proactive monitoring strategies. 相似文献

Residual attentional capacity amongst young and elderly during dual and triple task walking 总被引:1,自引:0,他引:1
Walking is considered an automatic function which demands little attentional resources. Thus a residual attentional capacity is available for a concurrent task (dual task). Minor age-related deficits in postural control may minimize the residual attentional capacity, however this may not be detected by a simple examination of the individuals gait performance. This study investigated the use of challenging dual task combinations to detect age related changes in gait performance. Eleven community-dwelling elderly (mean age 76 years) and 13 young subjects (mean age 26 years) participated in the study. The participants walked along a figure-of-eight track at a self-selected speed. The effect of introducing a concurrent cognitive task and a concurrent functional motor task was evaluated. Stride-to-stride variability was measured by heel contacts and by trunk accelerometry. In response to the cognitive task the elderly increased their temporal stride-to-stride variability by 39% in the walking task and by 57% in the combined motor task. These increases were significantly larger than observed for the young. Equivalent decreases in trunk acceleration autocorrelation coefficients and gait speed were found. A combination of sufficiently challenging motor tasks and concurrent cognitive tasks can reveal signs of limited residual attentional capacity during walking amongst the elderly. 相似文献
