This research deals with individual differences in the ability to focus and divide attention. Eighty-five subjects performed visual search and auditory detection tasks in three conditions: single channel, focused attention, and divided attention. Reaction time (RT) was fastest in the single channel condition, intermediate in the focused attention condition, and longest in the divided attention condition, and these effects were much stronger in the auditory than the visual task. Correlations among RTs in the three conditions were very high within modality (>.88), and lower between modalities (.5 to .6). The correlational data was well fit by a model that included separate factors for the visual and auditory tasks. Measures from the three attentional conditions within each modality loaded equally on these factors. The data provided no evidence for distinct abilities to divide or focus attention. 相似文献

Adolescents experiencing personal difficulties commonly evidence their problems while in school. Group psychotherapy within the school setting can be an effective means of helping an adolescent subject to stress at home. Parental alcoholism is the problem shared by a group composed of six students led by a clinical social worker. The broader implications of group therapy in a school setting as a means of helping young people with problems that interfere with their education and socialization are also considered. 相似文献

In a study of individual differences in long-term memory access, university undergraduates verified (1) whether an item was a member of a category, (2) whether two items belonged to the same category, and (3) whether two words had the same name. Reaction times from these tasks were correlated with verbal ability, as measured by performance on a standardized test of vocabulary and reading comprehension. A relationship was found between verbal ability and reaction time in the verification tasks. These results are contrasted with those of Hogaboam and Pellegrino (1978), who failed to find such a relationship. The results indicated that the various reaction time measures form a single factor that bears a moderate relationship to reading and vocabulary measures. 相似文献

The DIAGNOSER is a HyperCard tutorial construction system based on a framework of naive physics conceptions and developed for high school classroom use. It assesses students’ conceptions in a domain, and prescribes a course of action on the basis of that assessment. In addition, it collects data for instructional enhancement and theoretical investigations. It is sufficiently general to allow tutorials to be developed in other knowledge domains, such as probability, economics, and psychology. An advanced version exploring naive conceptions of circuit electricity is also discussed. 相似文献

Two studies demonstrated a functional relationship between a peer modeling procedure and the treatment of feeding disorders with 2 young children. In the first experiment, the use of a peer model treatment package was shown to induce swallowing in a child with dysphagia who had never swallowed food or liquid. In the second experiment, a child who consistently declined food was induced to increase food acceptance as a function of the same peer modeling package. In the latter experiment, a peer-mediated procedure, consisting of rotated opportunities to consume food with a peer, was found to increase consumption more than did modeling alone. The first experiment used a multiple baseline design across solids and liquids, and the second used a multiple treatment design. The results of both experiments are discussed as new and nonaversive treatments for feeding disorders of young children who are imitative. 相似文献

A community-reinforcement approach to alcoholism 总被引:5,自引:0,他引:5
Several theoretical approaches to alcoholism exist. An opérant reinforcement approach was used in the present study to develop a new procedure that rearranged community reinforcers such as the job, family and social relations of the alcoholic such that drinking produced a time-out from a high density of reinforcement. The results showed that the alcoholics who received this Community-Reinforcement counseling drank less, worked more, spent more time with their families and out of institutions than did a matched control group of alcoholics who did not receive these procedures. This new approach appears to be an effective method of reducing alcoholism. An analysis in reinforcement terms is presented of the etiology, epidemiology, and treatment of alcoholism. 相似文献

Amplitude changes in the auditory event related response reflect differences in linguistic content and the level of processing of spoken sentences. Thus, the neurophysiology of the cognitive processes underlying speech perception can be evaluated by noninvasive techniques. Semantically correct, semantically incorrect, and grammatically incorrect sentences were processed either semantically or syntactically by 25 subjects while their EEGs were recorded. The amplitude of the P250 component to each word varied with processing level. A slow positive wave appeared after semantically correct sentences regardless of the linguistic processing level. N480 and P780 components were observed following words which made the sentences incorrect. 相似文献
