The process of group categorization, as suggested by Tajfel and Turner's (1979) theory of intergroup comparison, was examined under conditions of intergroup conflict in Northern Ireland. The theory predicts that under “normal” conditions groups have a need to distinguish themselves from others. The present study investigates how individuals in Northern Ireland under extreme environmental pressures to identify both their own and other groups, can use learned stereotypic cues in making such categorizations. Results suggested that such limited information was highly effective in the process of categorization, with both Protestant and Catholic subjects exhibiting significant agreement and confidence in identifying unknown persons on the basis of stereotypic cues Conflicting information was found to reduce subject's confidence levels, with conflicting Catholic cues being more disruptive than Protestant ones 相似文献

This study employed a self-report questionnaire in a Solomon four-groups design to assess the efficacy of suicide intervention classes in achieving their instructional objectives. Because adolescents are often the first to know of a peer's suicidal thoughts or plans, the goal of the classes was to increase the likelihood that students who come into contact with potentially suicidal peers can more readily identify them and will be consistently inclined to take responsible action on their behalf. Students who participated in the classes as compared to controls showed significant gains in relevant knowledge about suicidal peers and significantly more positive attitudes toward help seeking and intervening with troubled peers. Results of this study will be used to strengthen components of the lessons aimed at enhancing the likelihood of performance of responsible interventions 相似文献

Depression After Traumatic Brain Injury: A Review of Evidence for Clinical Heterogeneity 总被引:3,自引:0,他引:3
Depression represents a major source of disability among individuals who have suffered a traumatic brain injury (TBI), with estimates of prevalence in this population ranging over 50%. In comparison with other sequelae of TBI, depression is often poorly conceptualized and treated among acute care and rehabilitation professionals. One reason for this is the lack of clear etiological models for the development of depression following TBI. This paper argues that post-TBI depression actually represents a heterogeneous category, with multiple etiologic pathways and clinical implications. The literature in this area is reviewed, with an emphasis on an appreciation of the diversity within this clinical population. Conclusions focus on suggestions for differential diagnosis and treatment options. 相似文献

Physical appearance influences behavior in a number of environments, yet surprisingly little is known about the influence of physical attractiveness on the bargaining process. We conducted an ultimatum game experiment to investigate the influence of physical attractiveness and gender on ultimatum game decisions. Results from this study revealed no significant differences in the offers or demands attractive and unattractive people made. However, attractive people and men were treated differently by others. Consistent with the notion of a “beauty premium,” attractive people were offered more, but more was demanded of them. Men were also offered more, and less was demanded of them. We discuss implications of these results with respect to bargaining and the labor market. 相似文献

In a performance setting, subjects were given an opportunity to cheat without fear of detection on puzzle problems. Subjects were led to believe that successful performance was due to ability in some conditions, but to luck in other conditions. In fact, most of the problems were insolvable, so that success was impossible without cheating. Self-awareness was induced in half the subjects by having them sit in front of a mirror and listen to a tape recording of their own voice as they worked on the puzzle problems; the remaining subjects were not exposed to a mirror and listened to a tape of someone else's voice as they worked on the problems. It was predicted that cheating frequency would be higher under ability attribution conditions than under luck attribution conditions, and that this effect of performance attribution would be greater among self-aware subjects than among non-self-aware subjects. Results confirmed these hypotheses. Discussion centered on the differential use of morality and competence standards for behavior when in a state of self-awareness. 相似文献

Several single studies concerned with work training with the mentally handicapped have been reported in the literature (Bitter & Bolanovich, 1966; Huddle, 1967; Gold, 1969; Screven, Straka & Lafond, 1971). Most have been concerned with issues of acquisition and motivation to perform. No studies have been reported which focus on the evaluation of different techniques of training or which assess rate of acquisition against that of non-handicapped controls. The aim of this experiment is twofold. It uses a complex task, analysed by MTM-2, to enable comparison between the performances of mentally handicapped adults and adults from a 'normal' population, in the acquisition of new work skills. Various strategies of training were compared and the increase in the rate and quality of performance following acquisition was measured for both, in terms of speed and accuracy of production. Results add further support for the notion that the potential of mentally handicapped individuals is commonly underestimated. It is hoped that the findings provide a basis from which further experiments can be developed and evaluated. 相似文献

Entering seventh grade, most children believe that smoking endangers their long-term health. Nevertheless, three sources of social pressure were found to often have an overriding influence to begin smoking: peers, models of smoking parents, and media. Interventions were developed to train children to cope with these pressures. Also stressed were immediate rather than long-term physiological effects of smoking. A dependent measure was utilized that generates increased validity of self-reports of smoking. A 10-week investigation was completed with 750 male and female students entering the seventh grade. Rates of onset of smoking in treatment groups were significantly lower than in a pretest-single posttest control group. 相似文献

Kagan (1965a) developed the concepts of impulsive and reflective cognitive styles (conceptual tempo) to add a new dimension to the understanding and assessment of human intelligence. Although latency (the principal component of conceptual tempo) is negatively correlated with academic performance, it may not be necessary to modify latency in order to modify accuracy. With 40 disadvantaged preschool children, it was found that reinforcing long latencies in choice tasks did not increase accuracy and vice versa, and that reinforcing both long latencies and accuracy was no more effective than reinforcing accuracy alone. These data were used to question the usefulness of the construct of conceptual tempo.This article is based on a master's thesis prepared by the first author under the supervision of the second author. 相似文献
