The sibling relationship has recently become the focus of much research in developmental psychology. The family system perspective implies the presence of a sibling with mental retardation will impact on the psychological development and functioning of their typically developing siblings. Past reviews of the literature have found this impact to be negative but there is the suggestion of positive consequences to having a sibling with mental retardation. The present meta-analysis sought to quantitatively integrate 25 studies and 79 effect sizes from the literature on the siblings of individuals with mental retardation. A small negative effect for having a sibling with mental retardation was discovered that could not be attributed to a publication bias or some other artifact. This negative effect was greatest for direct observation measures, measures of psychological functioning, especially depression, and for children. Limitations to this meta-analysis and directions for future research are discussed. 相似文献

This study evaluated whether a concurrent group teaching procedure, in which all students respond simultaneously, could be used for persons with moderate or severe mental retardation. The teaching procedure used was the Task Demonstration Model, a program based on stimulus-control research and the fading techniques of behavioral psychology. Three teachers and three groups of students participated. Results showed that the teachers increased their rates of questions and instructions, positive feedback, and use of functional materials, but they reduced their rate of prompts to almost zero. Students increased their percentage and rate of correct responding as well as their engaged time. In addition, maladaptive responding, for which there were never any direct consequences, decreased from 45% to 10% for 8 of the 14 students. Results are discussed primarily in two areas: (a) changing stimulus control from teacher prompts to critical elements of the items being taught, and (b) reasons for the reduction of maladaptive behavior for 8 of the subjects. 相似文献

We investigated the separate and combined effects of a behavioral intervention and methylphenidate (Ritalin®) on disruptive behavior and task engagement in 3 children with severe to profound mental retardation. The behavioral intervention involved differential reinforcement of appropriate behavior and guided compliance. All 3 children demonstrated decreased disruptive behavior and improved task engagement in response to the behavioral intervention. Two of the 3 children demonstrated similar improvement in response to methylphenidate. Although both interventions were highly effective for these 2 participants, the relative efficacy of the interventions varied between the 2 children. There was no evidence of an additive or synergistic effect of the two interventions, but the high efficacy of each intervention alone limited our ability to detect such effects. 相似文献

In this study we attempted to operationalize, measure, and increase happiness among people with profound disabilities. Happiness indices were defined and observed among 5 individuals. Validation measures indicated that (a) increases in happiness indices were observed when individuals were presented with most preferred stimuli relative to least preferred stimuli, (b) increases in unhappiness indices were observed when they were presented with least preferred relative to most preferred stimuli, and (c) practitioner ratings of participant happiness coincided with observed indices. Subsequently, classroom staff increased happiness indices through presentation and contingent withdrawal of activities. Results suggested that a behavioral approach can enhance happiness as one aspect of quality of life among people with profound disabilities. Research directions are offered that focus on using a behavioral approach to investigate other private events that are important among people with disabilities. 相似文献

Four experiments were conducted to examine variables associated with response practice as an instructional technique for individuals with intellectual disabilities. In Experiment 1, the effect of the cover component in the "cover write" method was evaluated, as were the comparative effects of written versus oral practice of spelling words by rehabilitation clients. The results showed that the cover procedure generally did not enhance performance over and above that produced by practice alone, and written practice generally was not superior to oral practice. Experiment 2 demonstrated that less response practice (i.e., five times) was as effective as more practice (i.e., 10 and 15 times) for teaching spelling to adolescents with developmental disabilities. Experiments 3 and 4 also showed that even less response practice (i.e., one time) was as effective as more practice (five times), and irrelevant practice following errors was as effective as relevant practice for teaching spelling and sight vocabulary to adolescents with behavior disorders and developmental disabilities, respectively. The findings suggest that a parsimonious procedure of limited response practice and positive reinforcement may be effective for the tasks and populations studied. 相似文献

Inclusive instruction was provided for three older adults with profound mental retardation in a water exercise class at a local YMCA. The older adults were taught to exercise through the use of systematic prompting. A multiple baseline design across participants with an embedded reversal was used to evaluate the impact of a personal trainer. The three participants performed the exercise, but regressed without the assistance of the trainer, as demonstrated by the reversal. Data collected during peer prompting and maintenance conditions indicated that the participants continued to exercise at levels higher than baseline but lower than with a personal trainer. 相似文献

A pretest/posttest control group design was utilized to examine the effect of social skills training on social interactions with peers, conversational interactions with a novel partner, and ratings of overall social functioning. The results failed to support the hypothesis that social skills training could increase the generalization of overall conversational responding of mentally retarded adults. The results showed that social skills training augmented with self-monitored videotape feedback could not optimize the effects of social skills training alone. The subjects did demonstrate acquisition of the targeted behaviors during training by meeting preestablished criteria for all of the training sessions. However, the subjects failed to generalize those behaviors across settings to in vivosocial situations. 相似文献

In this two-experiment investigation, the long-term (at least 6 months) employment of 51 moderately mentally retarded clients who were placed into 64 supported employment positions was first evaluated relative to 10 training and posttraining components that comprised a supported employment training package. In Experiment 1, chi-square analyses were used to identify three components that differentiated successful (employed for at least 6 months) from unsuccessful clients. In Experiment 2, 4 successful clients were further evaluated in a nonconcurrent multiple baseline design to determine whether the three variables identified during the group analysis (client advocate, collateral behavior, and follow-up plan) were included in the training packages. These results are discussed in terms of the need to establish better the functional variables of supported employment training programs. 相似文献

This study compared training in two language systems for three severely handicapped, nonvocal adolescents: the Bliss symbol system and an iconic picture system. Following baseline, training and review trials were implemented using an alternating treatments design. Daily probes were conducted to assess maintenance, stimulus generalization, and response generalization, and data were collected on spontaneous usage of either language system throughout the school day. Results showed that students required approximately four times as many trials to acquire Bliss symbols as iconic pictures, and that students maintained a higher percentage of iconic pictures. Stimulus generalization occurred in both language systems, while the number of correct responses during responses generalization probes was much greater for the iconic system. Finally, students almost always showed more iconic responses than Bliss responses in daily spontaneous usage. These results suggest that an iconic system might be more readily acquired, maintained, and generalized to daily situations. Implications of these findings for the newly verbal person were discussed. 相似文献

This study evaluated the effects of a fine mist of water applied to the face contingent upon self-injurious behavior (SIB) exhibited by profoundly retarded persons. In Experiment 1, results of individual reversal designs showed substantial reductions in a variety of SIB's (mouthing, hand biting, skin tearing, and head banging) for seven participants. In Experiment 2, two participants who frequently bit their hands were each observed in two different settings. Following initial baselines in each setting, a series of manipulations was undertaken to compare the effects of mild verbal punishment (“No”) with those of a combined treatment (“No” plus mist procedure). Results in one setting indicated that “No” suppressed SIB only after it was first paired with the water mist. Data also suggested that, once acquired, the punishing properties of “No” could be extended to a second setting in which the mist was never applied, and that these effects could be generalized across therapists. Results of these experiments indicate that the water mist procedure may be an effective alternative to traditional punishment techniques. Although conclusions regarding generalization are limited due to the brevity of the maintenance conditions, the data suggest that treatment gains may be transferred to more acceptable forms of social punishment and reinforcement. 相似文献
