This study examined patients' illness representations assessed shortly after an acute coronary syndrome (ACS) as predictors of posttraumatic stress symptoms six months later. Illness representations were assessed in ACS patients using standard measures at a home visit three weeks after discharge from hospital. Posttraumatic stress symptoms were assessed at the same time, and again six months later. Patients were aged 61 years on average, the majority being men (89.8%) of white European decent (89%). Greater posttraumatic symptoms at six months were associated with beliefs that the illness would last a long time (timeline), that it had an unpredictable time course (timeline--cyclical), greater consequences, less personal and treatment control, poorer illness coherence and stronger negative emotional representations (emotional upset relating to the illness; p?0.05). In multiple regression analyses, controlling for demographic, clinical and psychological factors (age, gender, ethnicity, social deprivation, ACS severity, negative affectivity and cardiac symptom recurrence), more intense emotional representations (β?=?0.146, p?=?0.041) and reduced illness coherence (β?=?-0.133, p?=?0.029), emerged as independent predictors of posttraumatic symptom severity at six months. There was a near significant effect for personal control (β?=?-0.113, p?=?0.058). These results demonstrate the importance of illness representations of ACS in predicting longer-term posttraumatic stress symptoms. 相似文献

This paper outlines a new approach to the study of bystander intervention. Using insights derived from self‐categorization theory (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987), we explore the social category relations among those present in the context of physical violence. The paper describes two experiments that manipulate the social category relations between (a) bystander and fellow bystanders, and (b) bystander and victim. Analysis indicates that fellow bystanders are only influential when they are in‐group rather than out‐group members. Furthermore, bystanders are more likely to help victims who are described as in‐group as opposed to out‐group members. Overall, the findings suggest an important role for a self‐categorization perspective in developing strategies to promote bystander intervention. 相似文献

Semi-structured interviews with nine U.S. Midwestern inner-city single Black mothers of young children were analyzed using inductive qualitative methods to determine similarities and differences in their expectations and goals for sons versus daughters. Drawing on critical race feminism, we developed links between these ideas, mothers’ personal experiences with men, and prevailing Black gender ideologies. Mothers valued independence and strength in daughters and hoped to prevent early sexual activity. Mothers with sons couched their aspirations in terms of counter-examples but were fatalistic. Childrearing goals reflected fears based on personal experiences. 相似文献

Tested the hypothesis that individuals with an external locus of control are sensitive to the occurrence of noncontingency and will not display the illusion of control. Internals, who view outcomes as response dependent, should succumb to the illusion. One hundred thirty-eight students were asked to judge the amount of control they had over the onset of a noncontingent green light in one of two conditions: 25% green light onset and 75% green light onset. Both internals and externals demonstrated the illusion of control: they rated themselves as having more control when they received a green light on 75% of the trials, despite the fact that green light onset was response independent. These findings suggest that externals are doubly impaired. Their bias toward perceived response-outcome independence is given up when it would be most helpful, that is, when environmental cues suggest control in an objectively uncontrollable situation. 相似文献

The present study evaluated the effects of behavioral training on visual acuity and refractive error in myopic adults. Twenty volunteers were matched on the basis of refractive error and one member of each matched pair was randomly assigned to either Fading and Feedback training or a no-treatment control condition. Visual acuity was measured with both recognition and resolution measures. Refractive error was measured subjectively using the LaserSpec optometer, and objectively by two retinoscopic examinations performed by an ophthalmologist with and without cycloplegia. The results indicated significant increases in recognition visual acuity, but not resolution visual acuity for trained subjects compared to the no-treatment controls. Trained subjects did not show improvement in refractive error on any measure, and refractive error changes were not correlated with changes in either measure of visual acuity. These data suggest that the visual acuity improvements typically found with behavioral training are not associated with changes in refractive error. 相似文献

The present study was designed to assess whether applicants for a sex-incongruent position would be evaluated less favorably by personnel administrators than applicants for a sex-congruent position. It was predicted that negative evaluations of sex-incongruent applicants would increase as a function of participants' reliance on sex-role stereotypes. Forty-four personnel administrators were asked to review the qualifications and evaluate one of four job applicants. Sex of the applicant and sex-orientation of the position were systematically varied. Participants were presented with credentials of a male or female applicant for a traditionally male- or female-oriented position. While results did not support Cohen and Bunker's contention that sex-incongruent job applicants would be viewed less favorably, the data did suggest that evaluations of the sex-incongruent applicants (especially the female applicant) varied as a function of sex-role stereotyping.The authors wish to gratefully acknowledge the assistance provided by Thom Hurlburt, Joan Van Tassel, and Amy Post. 相似文献

The parafascicular (PF) nucleus, a posterior component of the intralaminar nuclei of the thalamus, is considered to be an essential structure in the feedback circuits of basal ganglia-thalamo-cortical systems that critically participate in cognitive processes. To study the PF contribution to processing of behaviorally significant information during specific episodes of learning, we investigated the effects of damaging the PF nucleus in the acquisition of a natural form of social olfactory learning, the socially transmitted food preference (STFP) task. This task is a non-spatial paradigm that exhibits some of the characteristics of relational memory because it requires that animals use information obtained in one episode to guide later behavior in different circumstances. Adult male Wistar rats were submitted to pretraining bilateral N-methyl-D-aspartate (0.15 M, pH 7.4) lesions of the PF (0.4 microl/side, 0.2 microl/min). The behavioral effects of PF lesions were compared to vehicle- and sham-operated control groups and two retention delays were considered in separate groups: immediately (Lesion-I, Vehicle-I, and Sham-I groups) and 24h after training (Lesion-24, Vehicle-24, and Sham-24 groups). PF lesions produced delay-independent impairments in the STFP suggesting that this nucleus might modulate the acquisition of this odor-odor association task. Results are discussed in the context of medial prefrontal cortex deafferentation induced by PF damage. 相似文献
