We report two studies which evaluate practically-oriented programmes of interprofessional contact involving doctors and social workers. The evaluation is based on the ‘contact hypothesis’ in intergroup relations, and highlights four sets of dependent measures: background perceptions, ingroup and outgroup ratings, knowledge, and judgements about work with outgroup partners and experienced contact. Consistent with the contact hypothesis, both studies revealed an improvement in outgroup attitudes, evidence of mutual intergroup differentiation (acknowledged superiority of ingroup and outgroup on independent dimensions), and increased outgroup knowledge. Greater change in Study 2 is interpreted in terms of its longer duration, and the opportunity it provided for contact with multiple outgroup members, compared with a single outgroup partner in Study 1. These findings from field studies are consistent with results from published laboratory experiments. 相似文献

It is argued that conservation judgements are based on a particular combination of logical necessity and empirical belief. The empirical belief is that a given transformation will not alter a particular quantity (Elkind's conservation of identity). The logical aspect is a transitive deductive argument containing an initial equivalence of two quantities and the conservation of identity belief as premises which lead to the conclusion of maintained equivalence (Elkind's conservation of equivalence). In two experiments, it is shown that conservation of identity beliefs can be manipulated in subjects who have long since developed the capacity for transitive deductive inference. Untrained 10 year olds were unaware of how sublimation acts to alter certain quantities over particular transformations of shape. And untrained adults incorrectly believed that both the area and perimeter of a closed figure would be conserved over transformations which elongated the figure. Both groups of subjects could be trained in the correct conservation of identity beliefs and this affected their conservation of equivalence judgements in predicted ways. It is suggested that the locical aspect of conservation is developmentally stable and that the empirical aspect varies widely across problems and individuals because of its dependence on relevant experience. 相似文献

Magnetic resonance imaging is a promising technological advance used for research and diagnosis of disease. The procedure has no risks, except when uncooperative patients require sedation. Four normal children participated in simulated scans to study the effects of (a) antecedent changes in the imaging environment and (b) operant conditioning of movement inhibition. Changing the environment can decrease movement, but operant contingencies were necessary to decrease movement to a level that, in most cases, would allow the procedure to occur without sedation. 相似文献

We studied the effects of a Learning Station on the completion and accuracy of math homework of middle school students who had chronic homework problems. The Learning Station was a three sided free-standing panel with theoretically and empirically-based components involving (a) stimulation (color, music, activity breaks, and choice) and (b) self-attention (mirror and self-monitoring). Two students who used the Station tripled their accuracy and the amount of homework completed as assessed in a multiple baseline across participants design. One student with high academic abilities elected not to use the intervention, because he worked quickly (albeit carelessly) at school to complete his homework during baseline and during intervention. The practical and research implications of the findings are discussed. 相似文献

We examine production of word definitions by people with probable Alzheimer's disease (pAD). In the first experiment, healthy young adults defined concrete, imageable nouns to provide a baseline of definitional ability. Analysis of these definitions identified the key defining features of each target item. In the second experiment, pAD participants and elderly controls produced definitions of the same items. In the third experiment, healthy young participants rated the adequacies of these definitions. Although as expected the pAD participants produced fewer good definitions than the other two groups, most of their responses still contained some relevant information. pAD definitions contained fewer pieces of information and the information they produced was more tangential to the primary concept than that provided by the young or elderly participants. We identify two possible explanations in semantic loss and metalinguistic impairment. We consider metalinguistic impairment to provide the more plausible explanation of pAD patients' definitional performance. 相似文献

In this article we describe a project which aims to ensure prevention and continued protection from violence for family members. We outline our theoretical approach to assessment and working with violence in family relationships and the associated ethical problems. We identify three recurrent themes: risk, collaboration, and responsibility. We focus on our work with couples, where the man is violent towards the woman. Within this discussion we identify other important clinical issues. 相似文献

A short-term group treatment model for gay male survivors of childhood sexual abuse living with HIV/AIDS 总被引:1,自引:0,他引:1

HIV-positive gay male survivors of childhood sexual abuse (CSA) face three layers of trauma: childhood abuse, homophobic oppression, and HIV/AIDS. Additionally, CSA has been shown to increase HIV risk behavior among gay men, and the trauma of HIV infection often parallels the experience of CSA. Effective coping strategies are particularly important for people living with HIV/AIDS in order to adapt to physical, psychological, and social implications of infection. However, coping strategies once adaptive in the context of CSA may become maladaptive in adulthood. Interventions are needed that enhance coping and address CSA for survivors living with HIV/AIDS to protect their own health and to prevent new transmissions. This article presents a group model found to be efficacious for treating gay male survivors of CSA living with HIV/AIDS. 相似文献
