Teaching autistic and severely handicapped children to recruit praise: acquisition and generalization.

Autistic and severely handicapped children were taught to ask questions (e.g., "How did I do?") and make requests (e.g., "Check it out") to recruit or set the occasion for praise from an adult. Teaching occurred during structured sessions in a community-based group home. Generalization of the children's use of these behaviors was evaluated during other activities in the teaching area, with other staff members in different areas of the home, and at each child's academic classroom. The children learned the behaviors to cue or set the occasion for praise independently and used these behaviors in all of the generalization settings. In the generalizations settings, the children were frequently successful in recruiting praise.

Development of a continuum of services for children and adults with autism and other severe behavior disorders.

The development of a 12-step continuum of services for individuals with autism is described. The operation and funding of outreach parent training; homebased early intervention; preschool, vocational, and adult intermediate care; and school consultation programs are outlined. The use and importance of evaluative data on both treatment outcome and staff skills are emphasized.

The role of response delay in improving in the discrimination performance or autistic children.

This study investigated the influence of a response delay requirement on the discrimination performance of autistic children. In the context of a multiple baseline design with subsequent repeated reversals, two conditions were compared: a no-response-delay condition, where the child was allowed to make the target response immediately after presentation of the discriminative stimulus versus a response-delay condition, where the target response was permitted three seconds following the discriminative stimulus when the therapist would signal the child to respond. The results showed that the response-delay condition produced higher levels of correct responding than the no-response-delay condition. In addition, teachers in the research setting rated the response-delay procedure to be a practical and effective teaching technique that could be implemented in a classroom setting. The results were discussed in relation to the literature on impulsivity, and were interpreted as indicating that the response-delay procedure provides a valuable technique for teaching autistic children.

Contingent exercise: a mild but powerful procedure for suppressing inappropriate verbal and aggressive behavior.

Two single-subject experiments were conducted in public school classrooms for severely emotionally disturbed children. Both experiments investigated the effects of a treatment requiring a child to exhibit a simple exercise task after a verbal or aggressive response, using reversal and multiple-baseline designs. The independent variable, contingent exercise, required standing up and sitting on the floor five to ten times contingent on an inappropriate behavior. It was found that contingent exercise was easy to carry out, and following it, the child quickly returned to the learning task that had been interrupted by the inappropriate behavior. The contingent exercise procedure required a minimum of prompting or manual guidance. Although contingent exercise was not topographically related to the inappropriate response, it decreased those responses dramatically. The results suggested that contingent exercise was not only more powerful than DRO but also could be administered independently. It was concluded that contingent exercise may constitute an alternative procedure that can be used by therapists confronted with severely abnormal behaviors. It would appear to be particularly relevant in settings where procedures such as timeout and painful consequences find restricted use. Finally, a number of guidelines have been proposed as a safeguard against the misuse of this mild but powerful procedure.

A supervision program for increasing functional activities for severely handicapped students in a residential setting.

This study was designed to increase the amount of time severely handicapped students living in a residential facility engaged in age-appropriate and functional activities. After a brief in-service training, a program involving instructions to supervisors and staff feedback was implemented in a multiple-baseline design across settings. Results showed that after the supervision program was implemented, the students' participation in activities increased. Further, these increases maintained when feedback was reduced from an average of 3 days a week during treatment, to once a month for a 5-month period.

Teaching functional community skills to autistic children using nonhandicapped peer tutors.

In this study, two autistic children were paired with normal peers who, after pretraining sessions, taught community skills to the autistic children. Data were collected during three conditions: baseline, modeling, and peer tutoring. Results demonstrated that no identified skills were acquired during the baseline and modeling conditions. However, direct instruction of each child by a peer tutor resulted in the learning and maintenance of functional community skills.

Developmental influences in teaching language forms to individuals with developmental disabilities.

The purpose of this experiment was to test the assumption that the sequencing of language goals for individuals with developmental disabilities should be based on the normal developmental sequence. In a series of two studies, phonetic sounds and syntactic structures representing different levels of normal development were taught to individuals with developmental disabilities. The results showed that (a) the majority of earlier emerging forms were acquired in fewer trials, (b) there was never an instance when the later emerging form was acquired and the earlier emerging form was not, and (c) the majority of earlier emerging forms were correctly produced at higher levels than the later emerging forms during probe sessions conducted 6 months after training. The results are discussed in terms of their implications for the development of language curricula for individuals with developmental disabilities.
