Transcultural counselling has its origins in practice rather than theory. There still remains a unified method to develop, and extensive epidemiological and clinical research to carry out, The growing body of work in the field of mental illness and racism, however, has encouraged clinical counsellors in the UK to describe, prescribe, develop and publish their work much more widely. Some recent developments are outlined against the background of political and social changes in Britain in the nineties. Implications for research, training and service delivery are examined.  相似文献

The hippocampus plays an important role in learning and memory, but the precise nature of that involvement remains uncertain. Transection of the perforant path, a primary input pathway to the hippocampus, has been shown to produce changes in reaction to novelty and acquisition of active avoidance; the nature and magnitude of these changes vary with lateral or medial perforant path damage. In a series of experiments on adult rats, the role of these pathways in spontaneous alternation, exploration, acquisition and extinction of conditioned responses, passive avoidance, and conditioned taste aversion was investigated. Lateral transection reduced exploration while medial transection facilitated acquisition of an active avoidance response; no effects were observed on any other measure. Results are discussed in terms of what perforant path damage might reveal regarding the interactions of the hippocampus with other brain regions.  相似文献

Visual analysis is taught in art history classes as a skill which aids a student in understanding a work of art in its appropriate conceptual or historical context. To provide a foundation for the design of computer-based lessons to train students in the skill, this study attempted to discover the strategies that novices employ when viewing a set of paintings. Verbal protocols obtained from novices in this study indicated that they described semantic features, or content, of paintings more than the formal elements, e. g. line, colour, shape, when viewing realist paintings. However, when presented with abstract, i. e. less semantically accessible paintings, novices shaply altered their approach and discussed formal elements over content. These findings suggest that an analysis of formal elements is not performed by a novice when a painting depicts a clear subject, but is attempted when the subject-matter becomes obscure. This implies that, at some level, novices realize that the meaning of a painting can be extracted from attention to the formal elements. Interestingly, novice protocols contained the same categories of strategies deemed important by experts. The lack of training in visual analysis was not notably manifest with respect to style. Of all formal dimensions, this one yielded the greatest discrepancy between novices and the expectations of instructors.  相似文献

Thirty-seven aphasic patients whose native language is Spanish were divided into four groups: (1) Broca's, (2) Wernicke's, (3) Conduction, and (4) Anomia. Phonological errors produced on repetition and object-naming tasks were analyzed in terms of type of transformation and degree of similarity between target and errors in terms of shared distinctive features. Segmental transformations were of the following types: (1) pure substitution, (2) pure addition, (3) deletion, (4) reduplicative addition (doublet creation)—anticipatory (right to left) or perseverative (left to right), (5) reduplicative substitution (doublet creation)—anticipatory or perseverative, and (6) mutual exchanges. Pure substitutions were the most prevalent, exchanges, the least. Some error types were found to differentiate significantly between aphasic populations. We suggest that different mechanisms may underlie the same error type for different aphasic populations.  相似文献

A number of explanations for the modality effect in immediate serial recall have been proposed. The auditory advantage for recall of recency items has been explained in terms of (1) the contributions of precategorical acoustic storage (PAS), (2) an advantage of changing-state over static stimuli, and (3) an advantage of primary-linguistic coding. Four experiments were conducted to evaluate these hypotheses. In the first, subjects viewed seven consecutive rectangles of different colors on a computer monitor. A small recency effect was obtained when the task was to recall the colors of the rectangles in order, with the size of the effect being independent of whether the rectangles remained stationary on the screen or moved in one of four directions. However, when the task was to recall the direction of movement of the rectangles, a larger recency effect was found. This pattern of results was interpreted as suggesting that recency effects are enhanced by changing-state stimulus information, but only when the changing-state information serves to identify the stimulus. Experiments 2 and 3 provided converging evidence by demonstrating an analogous recency advantage for changing-state visual stimuli that were somewhat different from those of Experiment 1. Experiment 4 demonstrated recency effects with synthesized speech stimuli that were substantially greater than were those found with the changing-state visual stimuli of the first three experiments. Implications of the results for the PAS, changing-state, and primary-linguistic hypotheses, as well as temporal-distinctiveness theories of recency, are discussed.  相似文献

Pragmatic reasoning schemas   总被引:16,自引:0,他引:16  
We propose that people typically reason about realistic situations using neither content-free syntactic inference rules nor representations of specific experiences. Rather, people reason using knowledge structures that we term pragmatic reasoning schemas, which are generalized sets of rules defined in relation to classes of goals. Three experiments examined the impact of a “permission schema” on deductive reasoning. Experiment 1 demonstrated that by evoking the permission schema it is possible to facilitate performance in Wason's selection paradigm for subjects who have had no experience with the specific content of the problems. Experiment 2 showed that a selection problem worded in terms of an abstract permission elicited better performance than one worded in terms of a concrete but arbitrary situation, providing evidence for an abstract permission schema that is free of domain-specific content. Experiment 3 provided evidence that evocation of a permission schema affects not only tasks requiring procedural knowledge, but also a linguistic rephrasing task requiring declarative knowledge. In particular, statements in the form if p then q were rephrased into the form p only if q with greater frequency for permission than for arbitrary statements, and rephrasings of permission statements produced a pattern of introduction of modals (must, can) totally unlike that observed for arbitrary conditional statements. Other pragmatic schemas, such as “causal” and “evidence” schemas can account for both linguistic and reasoning phenomena that alternative hypotheses fail to explain.  相似文献

This investigation examined how staff in an elementary school district perceived their school psychologists and how these perceptions differed across components of service and staff groups. We developed a School Psychological Service Questionnaire and then analyzed responses from regular education teachers, special education teachers, principals, and school psychologists in an urban school district. Although the findings are numerous, most noteworthy are, first, that consumer groups in the district had different perceptions than school psychologists about how school psychologists allocate their time and how this time should be allocated in the future. Second, consumer perceptions of school psychologists' knowledge generally were favorable. Third, in terms of domains appropriate for involvement by school psychologists, a factor analysis of consumer ratings revealed three relatively clear dimensions of recommended service provision — special education activities, interpersonal or school-climate activities, and administrative responsibilities. Fourth, the helpfulness of school psychologists, as perceived by consumers, related positively to frequency of contact. Fifth, differences in perception of school psychological services were evident across staff groups. Finally, comparisons between master's level and doctoral level school psychologists suggested numerous differences in how the staff perceived these service providers.  相似文献

Data from four reading-related tests, including a measure of knowledge about books and print conventions, and two demographic variables, obtained at the end of the first year of schooling, were used to predict a range of students' word and discourse reading achievement at the conclusion of that year. Students were enrolled in a reading program that emphasized either the subskills involved in breaking the reading code or the more holistic gaining of meaning from print. The results indicated that a measure of knowledge about books and print conventions is strongly related to end-of-year reading achievement, but that, over and above the other more traditional measures, it is a significant predictor of only one type of comprehension - that involving the inferential linking of two pieces of information separated in the text. Students in a subskills-emphasis program outperformed those in a meaning-emphasis program on tests of word knowledge but not of comprehension of discourse.  相似文献
