The distance from which an eyewitness views a perpetrator is a critical factor for eyewitness identification, but has received little research attention. We presented three mock-crime videos to participants, varying distance to three perpetrators (3, 10, or 20 m). Across two experiments, increased distance reduced empirical discriminability in the form of a mirror effect, such that correct identifications decreased while false identifications increased. Moreover, high confidence identifications were associated with high accuracy at 3 m (Experiment 1 and 2) and 10 m (Experiment 2), but not at 20 m. We conclude that eyewitnesses may be less likely to identify a perpetrator viewed at a distance, and also more likely to falsely identify an innocent suspect. Furthermore, there may be certain boundary conditions associated with distance and the impact it has on the confidence–accuracy relationship. More research is needed to elucidate the effect of estimator variable manipulations on the confidence–accuracy relationship. 相似文献
Intimate partner violence (IPV) is a severe health problem associated with significant distress and impairment in women. The most common psychiatric difficulty in battered women is posttraumatic stress disorder (PTSD); however, no research to date has investigated the relative impact of the severity of IPV and IPV-related PTSD symptoms on battered women's psychosocial functioning. In a sample of 177 sheltered battered women, PTSD severity was associated with considerable psychiatric morbidity, social maladjustment, and personal and social resource loss. Moreover, PTSD severity mediated the relationship between IPV severity and psychiatric severity and loss of personal and social resources. Results highlight the need for the assessment and treatment of IPV-related PTSD in battered women's shelters. 相似文献
Developing community capacity to improve health is a cornerstone of community-based public health. The concept of community
capacity reflects numerous facets and dimensions of community life and can have different meanings in different contexts.
This paper explores how members of one community identify and interpret key aspects of their community’s capacity to limit
the availability and use of tobacco products. Particular attention is given to examining the interrelationship between various
dimensions of community capacity in order to better understand the processes by which communities are able to mobilize for
social change. The study is based on qualitative analysis of 19 in-depth interviews with key informants representing a variety
of community sectors in Harlem, New York City. Findings indicate that the community is viewed as rich in human and social
resources. A strong sense of community identity and connectedness underlies this reserve and serves as a catalyst for action.

Few studies have systematically examined the influence of perceivers’ age on perceptions of sexual harassment. We sought to fill this gap, determine whether sexist attitudes mediate relations between age and sexual harassment perceptions, and whether relations between gender, sexist attitudes and perceptions are moderated by age. Results from an age-stratified sample of 965 students and staff employees at a US Midwestern university found a positive relationship between age and sexual harassment perceptions. Hostile sexism partially mediated this relationship, but age did not moderate correlations with gender or sexist attitudes. College-aged samples are less sensitive to harassment than older-aged samples, but the validity of other predictors of sexual harassment perceptions, such as gender and sexist attitudes, remains intact regardless of sample age. 相似文献
We examined the extent to which individual differences contribute to performance in a task considered to index implicit learning, the Hebb Digits task. Although Hebb Digits learning is considered to be equivalent for those with implicit and explicit knowledge of the repeating digit pattern, this study found that participants who developed explicit knowledge showed learning, whereas those without explicit knowledge did not. Additionally, participants who developed explicit knowledge outperformed participants without explicit knowledge on working memory measures, specifically the Automated Operation Span Task total correct score and absolute score. However, no significant differences were found between those who did and who did not develop explicit knowledge on the Hopkins Verbal Learning Task-Revised, which uses delayed recall to index long-term memory. These results suggest that learning and awareness in the Hebb Digits task relies on individual differences in working memory capacity. 相似文献
Objective: The study aimed to explore the psychological experiences of receiving a kidney transplant from a deceased donor and to examine resulting implications for renal services.
Design: A qualitative design was utilised within an interpretative phenomenological analysis (IPA) framework.
Main outcome measures: Semi-structured interviews were conducted with six adults (male = 5, mean age = 45 yrs) on their experiences of receiving a kidney transplant from a deceased donor. All participants had their transplant within the preceding 21 months. Data were analysed using IPA.
Results: The four elicited themes incorporate recipients’ positive feelings about receiving a transplant, mainly arising from the newfound freedom that this entails, in addition to strong feelings of gratitude towards their donors. They also capture challenges, such as the uncertainty of living with a transplanted kidney, and highlight the increased dependence on others throughout the transplant process.
Conclusion: The findings indicate a range of psychological, social and occupational experiences for participants. It is concluded that optimal care in renal services would incorporate a holistic approach to pre and post-transplant care; identifying and supporting the needs of transplant recipients. A biopsychosocial model of care may enhance service user well-being. Potential areas of future research are explored. 相似文献
This study examined the effects of external and internalized heterosexism and sexism on lesbians' mental health. Hierarchical regression analysis, controlling for education and income, identified recent sexual‐orientation‐based hate crime victimization, recent sexist events, internalized heterosexism, and the interaction of recent sexual‐orientation‐based hate crime victimization and recent sexist events as significant predictors of psychological distress, accounting for 31% of the variance. 相似文献
As research on the construction of a mental representation of referent gender in speech comprehension is scarce, this study examined whether factors identified in reading comprehension exert similar influence in speech comprehension. Conceptually replicating previous research, a sentence continuation evaluation task was set up in two modalities, as a listening task and as a time-confined reading task (i.e. to correspond to the time constraint when listening). In line with previous findings from self-paced reading paradigms we found gender representations in language comprehension to be grounded in the interaction between textual (grammatical) and background (stereotypical) information. Extending previous research, the effect of stereotypical information was however modulated by presentation modality. In all, although speech and reading comprehension share higher-level processes of comprehension, this study provides first evidence that differences in comprehension might occur due to differences such as orthographic access or attention allocation. 相似文献
Impulsivity has been conceptualized as influencing the expression of suicidal behavior. Adolescence is a developmental period characterized both by a relatively high rate of suicide attempts and a high level of impulsivity. The current study examined two behavioral measures (delay reward and disinhibition) and one self-report measure of impulsivity among girls with suicide attempt histories. Girls with multiple suicide attempts performed more impulsively on measures of delayed reward, and had higher self-ratings of depression and aggression than girls with either one or no suicide attempts. The multiple attempter girls' preference for immediate gratification may directly increase vulnerability to suicidal acts in the context of distressing states or indirectly increase risk by creating poor life experience over time. 相似文献
This study investigated the influence of two role stressors—role ambiguity and role conflict—on previously established relationships between mentoring activities—vocational support, psychosocial support, and role modeling—and prominent job attitudes. Full and partial mediation models were tested with a sample of 355 protégés. Results showed that both role conflict and role ambiguity completely mediated the relationships between psychosocial support and role modeling with job attitudes. There was also support for role conflict as a partial mediator of the relationship between vocational support and job attitudes. Additional analyses revealed that psychosocial support served as a suppressor-variable in this study. Implications for future research and mentoring practice are discussed. 相似文献
