The communication disorder in dialysis dementia is an integral feature of the syndrome. This report describes the communication disorder in a 67-year-old man over a period of 4 months from his admission to the hospital to his death. In the early stage of the syndrome, the most prominent feature was a speech problem, the characteristics of which may vary among cases. In the middle stage, it was difficult to distinguish among aphemia, aphasia, or a combination of dysarthria and confusional state. The severity of the problems in these stages was temporally related to the dialysis treatments. The final stage was characterized by constant mutism and was unrelated to the dialysis treatments. Death occurred 10 months after the communication problems emerged. Communication studies of dialysis dementia patients may offer a systematic method to monitor the course of the syndrome, its response to therapeutic trials, and a clinical model for the study of communication disorders in general.  相似文献

Presentence reports on 628 offenders were content analyzed. Regression analysis found that remorseful offenders received less severe sentences than non-remorseful offenders. Offenders convicted of minor offenses received more lenient sentences if they had used alcohol in conjunction with their crimes than if they did not use alcohol. The opposite was the case for offenders commiting serious crimes. Remorseful offenders with few prior alcohol-related convictions received less severe sanctioning than non-remorseful offenders with similar conviction records. In contrast, recidivists who were remorseful were dealt with more harshly than their non-remorseful counterparts.  相似文献

Motivating developmentally disabled children to participate in educational activities can be very difficult. This is especially true for children diagnosed autistic. Because there is some evidence to suggest that stimulus variation may influence motivation, the present study investigated the effects of constant vs. varied reinforcer presentation on correct responding and on-task behavior. Results from a reversal design showed declining trends in both correct responding and on-task behavior when the same reinforcer was consistently presented, whereas, varying the reinforcers produced significantly improved and stable responding. The results are discussed in relation to the literature on stimulus variation and its effects on responsivity.  相似文献

This research examined the effects of a self-instruction intervention on the relationship between cognitive level and conceptual tempo. Preoperational and concrete operational children received the Matching Familiar Figures Test prior to and after serving in either a no training control group, a content only control group, or a self-instruction group. Children in the content only control group received the same set of self-guiding strategy statements as those in the self-instruction group but without overt rehearsal of the statements. Cognitive level and conceptual tempo were strongly related; preoperational children tended to be classified as impulsive, concrete operational chidlren, as reflective. Although cognitive level predicted overall performance, with concrete operational children being more successful and more reflective than preoperational children, the influence of training was similar for both groups. On posttest, children in the self-instruction groups made more correct responses and were more reflective than children in the other two training groups.  相似文献

A simple and inexpensive system for coding and recording interaction patterns in small groups is described. It consists of a keyboard and a standard tape recorder, and it is capable of storing sequential data using up to 36 codes. Its main application is in the study of speaker-target patterns, but it can also be used in encoding up to 12 behavioral codes, or six speakers and 6 codes. The keyboard costs less than $200 and is used with conventional tape recorders and minicomputers available at most research sites.  相似文献

In a large study of the visual-perceptual deficits of epileptic children both Frostig's Developmental Test of Visual Perception and the verbal part of the German version of the WISC were administered. All WISC subtests correlated significantly with the Frostig Perceptual Quotients. Verbal IQs correlated significantly with scaled scores of all the Frostig subtests. From the results of this pilot study it was suggested that intellectual abilities of epileptic children as measured by the verbal WISC and visual perception as measured by the Frostig are both influenced by the same contingencies.  相似文献

Two experiments are reported in which the relationship between compliance with “do” and “don't” requests was examined with developmentally disabled children. In Experiment 1, a multiple baseline design across subjects with counterbalanced treatment conditions was used to evaluate a compliance training program composed of four phases: (a) baseline, during which no consequences were delivered for compliance, (b) reinforcement for compliance with one targeted “do” request, (c) reinforcement for compliance with one targeted “don't” request, and (d) follow-up with reinforcement on a variable ratio schedule for compliance with any “do” or “don't” request. Results of probes conducted before and after training within each condition indicated that generalized compliance occurred only with requests of the same type as the target exemplar (“do” or “don't”). In Experiment 2, these results were replicated in a classroom setting. Following collection of baseline probe data on student compliance, a teacher training program was successfully implemented to increase reinforcement of compliance first with one “do” and subsequently with one “don't” request of a target student. Results of multiple baseline probes across “do” and “don't” requests indicated that the teacher generalized and maintained reinforcement of compliance with other requests of the same type and to other students, with a resulting increase in student compliance with the type of requests reinforced. The impact of treatment on both teacher and student behavior was socially validated via consumer ratings. Implications of these findings with respect to response class formation and compliance training programs are discussed.  相似文献

Utilizing a cross-age tutoring context, this study examined the effects of reward on the teaching behaviors of the tutor, the tutor's subsequent motivation to continue to teach during a free choice period, and the social interaction between a tutor and a tutee. Third-grade boys and girls (n = 96) who exhibited a positive reinforcement style were asked to teach six addition problems to a first-grade boy or girl (n = 96). The children were randomly assigned to pairs and to one of the three reward conditions. In the performance-contingent reward condition, the tutors were promised a toy if the first-grader learned all of the arithmetic problems. In the noncontingent reward condition, the tutors were promised a toy for teaching the first-grader. In the no reward condition, the tutors taught the first-grader without promise of a toy. The results indicated that the social interaction was rated lower for the children in the performance-contingent group and that the tutors in this group spent less time teaching during the free choice period. However, neither the tutor's teaching style nor the tutee's post-test performance was adversely affected by the reward.  相似文献
