Recent research suggests that approximately one third of the population of homeless single adults suffer from severe mental illnesses. Despite multiple health, mental health, and social welfare needs, this population is often unable to obtain necessary housing and community-based services. For this reason, since 1982, the National Institute of Mental Health (NIMH) has undertaken a number of federal initiatives to encourage research and assist states and localities in improving services focused on this vulnerable subgroup of the homeless population. This article describes the target population, NIMH research findings, and current mental health service trends--with particular emphasis on two mental health programs established under the Stewart B. McKinney Homeless Assistance Act. Proposed future directions for federal research and evaluation efforts in this area are also discussed. 相似文献

Impact of perceived self-efficacy in coping with stressors on components of the immune system 总被引:5,自引:0,他引:5

This experiment examined the impact of experimentally varied perceived self-efficacy in exercising control over stressors on components of the immunological system. Immunological changes while coping with phobic stressors were measured within an intrasubject control design that included a baseline phase, an efficacy-acquisition phase, and a maximal-efficacy phase. In each of these phases, perceived coping self-efficacy, level of autonomic and endocrine activation, and several components of the immunological system were measured. Development of strong perceived self-efficacy to control phobic stressors had an immunoenhancing effect. A slow growth of perceived self-efficacy, heart rate acceleration, and cortisol activation attenuated immunological system status during the efficacy-acquisition phase. Rapid growth of perceived self-efficacy also predicted maintenance of immunoenhancement during the maximal perceived self-efficacy phase. 相似文献

Within a combined cross-sectional and longitudinal design, several analyses showed that student-rated teaching effectiveness in university professors declined with age. For 106 full-time psychology teachers, aged 26 to 55, who were studied for time periods ranging from 2 to 15 years, an overall negative correlation of r = -.33 (p less than .05) was found between age and general teaching effectiveness. A similar decrement with age occurred for items measuring specific teaching behaviors. Age accounted for 8% of the variance in general teaching effectiveness. 相似文献

The literature on lithium carbonate was reviewed for clues to the processes involved in mania. Lithium has proved effective therapeutically and prophylactically for mania and depressive disorders. Children and adolescents as well as adults tolerate lithium well. Side effects rarely are serious enough to necessitate having lithium therapy. Some success with schizophrenia and schizoaffective disorders has broadened the scope of lithium's therapeutic efficacy but also blunted the expectation for a direct relationship between lithium and the processes involved in mania. Research points to neurotransmitters as contributing to the etiology and symptom pattern of mania. 相似文献

According to traditional models of deindividuation, lowered personal identifiability leads to a loss of identity and a loss of internalized control over behaviour This account has been challenged by arguing that manipulations of identifiability affect the relative salience of personal or social identity and hence the choice of standards to control behaviour The present study contributes to an extension of this argument according to which identifiability manipulations do not only affect the salience of social identity but also the strategic communication of social identity. Reicher and Lvine (1993) have shown that subjects who are more identifiable to a powerful outgroup will moderate the expression of those aspects of ingroup identity which differ from the outgroup position and which would be punished by the outgroup. Here we seek to show that in addition, subjects who are more identifiable to a powerful outgroup will accentuate the expression of those aspects of ingroup identity which differ from the outgroup position but which would not be punished by the outgroup. This is because, when identifiable, subjects may use such responses as a means of publicly presenting their adherence to group norms and hence as a means of establishing their right to group membership. A study is reported in which 102 physical education students are either identifiable (I) or not identifiable (NI) to their academic tutors. They are asked to respond on a number of dimensions where pilot interviews show the ingroup stereotype to differ from outgroup norms. Expressions of difference from the outgroup position would lead to punishment on some of these dimensions (P items) but would not lead to punishment for others (NP items) The predicted interaction between identifiability and item type is highly significant. As expected, for NP items identifiability accentuates responses which differentiate the ingroup stereotype from outgroup norms. All these results occur independently of shifts in the salience of social identity. The one unexpectedfinding is that, for P items, identifiability does lead to decreased expression of the ingroup stereotype, but the diference does not reach significance. Nonetheless, overall the results do provide further evidence for the complex effects of identifiability on strategic considerations underlying the expression of social identity in intergroup contexts. 相似文献

A primacy effect in monkeys when list position is relevant 总被引:2,自引:0,他引:2

In Experiment 1 (1a and 1b), Rhesus monkeys (Macaca mulatta) learned lists of two-choice visual discriminations in which list position was relevant to discrimination performance. For example, Stimulus A was the rewarded stimulus if it was presented at List Position 1, but was not rewarded if it was presented at any other position in the list; similarly, Stimulus B was rewarded only at List Position 2, and so on. In learning these lists, all animals showed a marked primacy effect. In Experiment 2 (2a and 2b), Rhesus monkeys and Cynomolgus monkeys (M. fascicularis) learned lists of visual discriminations in which each visual stimulus occupied a fixed position in a list, but list position was not relevant to discrimination performance. For example, Stimulus E was always rewarded, and was always presented at List Position 1. To increase the salience of list beginning as a distinctive event, successive presentations of the list were separated by 24-hr intervals. In Experiment 2 there was no primacy effect, however. These results show for the first time that a primacy effect can be obtained in visual discrimination learning by monkeys. Furthermore, they suggest that it is obtained only when list position is relevant to the discrimination learning task. 相似文献

Eighty-six incumbents of three different jobs produced job-analytic ratings using either a decomposed (task-based) or a holistic (job-based) rating strategy. Approximately half of them received rater training in making inferential decisions. When tasks were less complex than the job as a whole, rating decomposition generally had positive effects on ratings' quality. Similarly, when the number of tasks rated was low to moderate, rater training was effective. A contingency approach, where limitations concerning the use of rating decomposition and inferential training were outlined, should serve to inform future uses and theories of rating aids in job analysis.We would like to acknowledge David Dorsey for his significant contribution to the rater training program. This article is a summary of the doctoral dissertation of Juan Sanchez, which was conducted under the supervision of Edward Levine. 相似文献

The purpose of this study is to examine the degree towhich various kinds of out-of-school activitiesadolescents participate in influence their schoolengagement, achievement, and perceptions of their lifechances. The conceptual framework outlined by theauthors suggests personal investments students makeoutside of school in meaningful, structured activitiesand with the help and guidance of adults serving asrole models have significant effects on variouseducational outcomes. To that end, the authors foundsome evidence suggesting that student participation instructured activities and religious activities andtime spent interacting with adults during tenth gradeappear to have positive and significant effects onvarious educational outcomes by Grade 12. Conversely,time spent hanging out with peers was consistentlynegatively associated with educational outcomes in thestudy, with few exceptions. The effects of time spentworking for pay and time spent alone were somewhatinconsistent throughout the analysis but this may bedue to methodological problems within the measures. The result of the analysis has implications forafter-school and summer school policies and programs. The authors discuss these implications and suggestfurther study of the effects of school context, familyinfluence, and the availability of community resourceson students' personal investments. 相似文献

J.F. Herbart (1824/1890b) provided a mathematical theory about how mental ideas (Vorstellungen) in consciousness at Time 1 (T1) could compete, possibly driving 1 or more Vorstellungen below a threshold of consciousness. At T1 a Vorstellung A could also fuse with another, B. If at a later T2, A resurfaced into consciousness, it could help B to re-resurface into consciousness. This article describes the historical and mathematical background of Herbart's theory, outlines the mathematical theory itself with the aid of computer graphics, and argues that the theory can be applied to the modern problem of predicting recognition latencies in short-term memory (Sternberg's task; Sternberg, 1966) 相似文献

Gender differences in dominance and play among preschoolers were examined. Forty-eight children in girl-girl or girl-boy dyads
engaged in masculine and feminine stereotyped activities. Girl-girl dyads displayed more cooperative play than girl-boy dyads.
Adventure themes predominated in boys during both activities but in girls only during the masculine activity. Boys had higher
functional play compared to girls while engaged in the feminine activity, and lower constructive play overall. Girls engaged
in more dramatic play during the feminine activity whereas boys engaged in more dramatic play during the masculine activity.
There was a trend for boys to refuse to follow the leads of girls during the masculine activity. Implications and interventions
in play are discussed.
The authors wish to express appreciation to the directors of the preschools that participated in this study. We would also
like to thank Sheri Wilhite for her help in the coding of the data. 相似文献
