This study investigated the use of videotaped exemplars taken from a regular education mathematics class to teach generalization of question asking. Three mildly handicapped fourth-grade students who asked few questions in the regular education class served as subjects. Measures of the frequency of question asking and percentage of accuracy on assignments were obtained in the regular class. Treatment included showing the videotapes to the subjects, structuring opportunities for rehearsing question asking, and providing feedback. The results showed training procedures implemented in the learning resource room were effective in increasing the level of participants' question asking and in improving their scores on assignments in the regular mathematics class. 相似文献

This article traces the emergence of supported employment as a result of philosophical changes in expectations for persons with disabilities, based on scientific developments that challenged traditional service-delivery models. Supported employment program characteristics also are reviewed, and the influence of applied behavior analysis is outlined. Finally, areas for future research in supported employment are discussed. 相似文献

This study investigated whether withdrawn adults living in a residential center for psychotic and mentally handicapped persons could serve as peer therapists to increase the social interaction of other withdrawn residents. Two pairs of residents served as participants. Treatments were introduced and evaluated within a multiple baseline with reversal design. After baseline, the peer therapist was instructed to increase the social interactions of a target peer through engagement in social interactions. The results demonstrated that the peer therapist increased the social interactions of target peers. However, these increases did not generalize to other residents until the introduction of a multiple peer therapist condition. The percentage of time the peer therapists interacted with other nontarget residents also increased throughout the study. These results were maintained during a 4-month follow-up condition. 相似文献

GENERALIZATION AND MAINTENANCE OF PRESCHOOL CHILDREN'S SOCIAL SKILLS: A CRITICAL REVIEW AND ANALYSIS
Lynette K. Chandler Roger C. Lubeck Susan A. Fowler 《Journal of applied behavior analysis》1992,25(2):415-428
This paper summarizes the results of a retrospective review of generalization in the context of social skills research with preschool children. A review of studies from 22 journals (1976 to 1990) that assessed generalization as part of social interaction research provided information concerning the prevalence of studies that have assessed generalization, common practices concerning the production and assessment of generalization, and the overall success of obtaining generalization and maintenance of social behaviors. A comparison of the most and least successful studies, with respect to generalization, revealed some differences concerning the practices employed by studies within each group. Differences differentially related to the production of generalization are discussed and recommendations are provided to guide and support future research efforts. 相似文献

Behavioral procedures have been used to teach manual communication skills to individuals with mental retardation, although few studies have examined the assessment of generalization of such skills beyond the teaching environment. In this study, we investigated the effectiveness of directed rehearsal for teaching and facilitating the generalization of manual signs by six hearing-impaired adults with mental retardation. The effects of directed rehearsal, alone and combined with positive reinforcement for correct responses, were compared to a no-training control condition in an alternating treatments design. Although directed rehearsal was superior to the no-training control condition in teaching manual signs, the procedure was more effective when combined with positive reinforcement. The combined procedure was used to facilitate the generalization of learned signs across a number of variables. The results showed that there were high levels of generalization by all participants across novel phrases, settings, and trainers but variable levels of generalization to another response mode by some subjects. Further, increased levels in overall vocal communication were found for most participants. 相似文献

The efficacy of a social skills training package in producing stimulus generalization, both with and without the systematic application of generalization programming techniques, was evaluated with 5 preschool children with hearing impairments. The evaluation was conducted within a multiple baseline design. Generalization probes were conducted daily. The social skills training package was implemented in a training setting and produced high, stable rates of social interaction in that setting. However, generalization of the social skills to new teachers, peers, and play activities did not occur until generalization programming strategies were applied in the original training setting. Using sufficient stimulus exemplars and contacting natural consequences appeared to be the key strategies for promoting generalization of social interaction. In addition, the use of supplementary procedures (e.g., a fluency criterion and treatment integrity checks) may have contributed to stimulus generalization. 相似文献

Three experiments used similar methods to investigate the pigeon's perception of saturation of monochromatic lights. This trial-wise procedure consisted of brief presentations of positive and negative stimuli in random sequence. Pecks to the positive stimuli were occasionally reinforced on a low fixed-ratio schedule. The first study determined absolute thresholds for "white" and monochromatic lights by establishing a discrimination between lights of various radiances and a dark key. Experiment II investigated generalization from a white light to various monochromatic lights under conditions that minimized the use of luminance as a cue. The third experiment examined discrimination of various monochromatic lights along a colorimetric purity continuum; responses to white light were reinforced, while responses to lights that combined white and monochromatic lights in various proportions were not. The results indicated that lights of different wavelength differ in saturation, but that all are discriminable from white. Wavelengths between 550 and 600 nm are least saturated for the pigeon, and saturation increases markedly as wavelength decreases below this region of the spectrum. 相似文献

The acquisition of prepositional motor responses in three handicapped preschool children was analyzed for three pairs of prepositions. Generalization of prepositional knowledge at each stage of acquisition was assessed by a series of probe trials. In addition, an analysis of the control of prepositional responses when objects of the preposition (OP) and direct objects (DO) were relevant cues was conducted. The effect of this object-cue procedure, as well as a specially devised prompting technique on acquisition, was also determined. Results indicated substantial control by OPs whenever this cue was relevant, but this did not affect acquisition of prepositional concepts when these cues were eliminated. Analysis of the probe data and the prompting technique suggested various ways in which instructional programs for teaching prepositional knowledge to handicapped children could be constructed in a simple and efficient manner. 相似文献

This study illustrated the use of normative behavioral observation data as a standard for evaluating the practicality of treatment effects produced in other settings. Three groups of eight subjects each, displaying relatively low proportions of appropriate classroom behavior when compared with regular classroom peers, were selected for treatment within an experimental classroom setting. The three groups were exposed to intervention procedures designed to reinforce either direct academic performance and/or facilitative nonacademic classroom responses. The treatment was effective in changing levels of appropriate behavior (1) above baseline levels in the experimental classroom, and (2) to within normal peer-defined limits when reintegrated into the regular classroom. Further, the data reflect successful maintenance of these effects for a seven- to 12-week follow-up period. Several applications of a normative model for evaluating treatment, generalization, and maintenance effects were presented and discussed. 相似文献
