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

Age differences in adults' processing of a dialectical or nondialectical prose passage were explored. Twenty young and 20 older adults read a dialectical or mechanistic passage and were tested for free recall and recognition after a 30-min delay (filled with vocabulary and paradigm belief scale). Older (vs. young) adults had significantly lower formistic and mechanistic scores and showed greater relative preference for relativistic and dialectical beliefs (paradigm scale). There were no age differences in amount of free recall or number of correct responses (hits) on recognition, but older adults produced more spontaneous dialectical distortions in recall of the mechanistic passage and more paradigm-congruent false alarms on recognition. There was also a move from absolute toward dialectical thinking on the paradigm scale and, among males, on the recognition measure. Dialectical scores (paradigm scale) were positively correlated, and mechanistic scores negatively correlated, with number of dialectical distortions on free recall (mechanistic passage), while dialectical scores were positively correlated with number of dialectical false alarms (dialectical passage). 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

The Exner (1986) system of scoring of the Rorschach results in a human movement response (M), which is far afield from Rorschach's original intent. This divergence can easily lead to faulty interpretations of a record as there is no need for kinesthetic reactions on behalf of the subject in Exner's system. The need to return to a traditional view of the M is demonstrated through a focus on theory and the literature that illustrates Rorschach's intent. The alteration of the M results in a scoring system which, due to its differences, must come up with a separate interpretative system and not consider itself part of the Rorschach system that Rorschach envisioned. 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

Investigations of face identification have typically focussed on matching faces to photographic IDs. Few researchers have considered the task of searching for a face in a crowd. In Experiment 1, we created the Chokepoint Search Test to simulate real-time search for a target. Performance on this test was poor (39% accuracy) and showed moderate associations with tests of face matching and memory. In addition, trial-level confidence predicted accuracy, and for those participants who were previously familiar with one or more targets, higher familiarity was associated with increased accuracy. In Experiment 2, we found improvements in performance on the test when three recent images of the target, but not three social media images, were displayed during searches. Taken together, our results highlight the difficulties inherent in real-time searching for faces, with important implications for those security personnel who carry out this task on a daily basis. 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
