A peer-mediated social network intervention to enhance the social integration of persons with moderate and severe disabilities.

Increasingly, parents, teachers, and students with disabilities are advocating for interventions that go beyond skill training to provide support for participation in integrated environments and support for friendships. The present research demonstrated a social network intervention for youths with moderate and severe disabilities. Two groups of nondisabled peers were recruited to participate in weekly discussions with an adult integration facilitator to increase opportunities for social interaction for 2 students (1 with autism and 1 who was moderately mentally retarded). The groups met to discuss social interactions that had occurred with the students with disabilities and to talk about strategies to promote greater inclusion of the students into ongoing social interaction. The nondisabled students participated in the design and implementation of social skills interventions during transition times and lunch. The nondisabled students used self-monitoring data sheets to record the quantity and quality of interactions. The frequency of interaction, number of opportunities for interaction, and appropriateness of social interactions were analyzed with a multiple baseline design. Results indicated that the social network intervention was successful in increasing the quantity and quality of interactions and that the network strategy promoted the development of friendships. The results are discussed in terms of the need for additional research showing the relationships between increases in social competence, peer-mediated intervention, and the development and support of friendship.

Effects of contextual competence on social initiations.

The frequency of social initiations and satisfaction with interactions in three dyads, each consisting of 1 student with disabilities and 1 nondisabled peer, were assessed under two alternating conditions: Condition 1 assessed the interactions around a set of four trained computer games, and Condition 2 assessed interactions when students were playing a set of four untrained computer games. Training was conducted with a multiple baseline design across participants and was followed by social interaction probes using an alternating treatments design. The results indicated greater frequencies of social initiation by 5 of 6 participants, higher degrees of game satisfaction by all participants, and equal or higher degrees of peer satisfaction by 5 of 6 participants when playing trained games in comparison to untrained games.

Stimulus class formation and concept learning: establishment of within- and between-set generalization and transitive relationships via conditional discrimination procedures.

Three students with moderate mental retardation were taught a complex stimulus class with a two-choice conditional discrimination procedure applied across eight 10-member stimulus sets. Each set was composed of five age-appropriate and five age-inappropriate examples of clothing, accessories, and leisure items (e.g., a Walkman radio). Discrimination training was programmed serially across each set, and generalization probes were conducted concurrently among all sets. Generalization probes consisted of unreinforced conditional matching trials with comparison items being drawn from (a) the set undergoing training (within-set probes), (b) sets not undergoing training (between-set probes), and (c) both sample and comparison items from different sets (transitive stimulus control probes). Results indicate that within-set generalization, between-set generalization, and transitive stimulus relations controlled responding by all 3 students for items that had been contingently associated with reinforcement. However, items that gained control of responding through within-set and between-set generalization alone (i.e., not acquired through contingent reinforcement) remained at baseline levels during transitive stimulus control probes. Results are discussed in terms of a taxonomy of multiple sources of stimulus control that underlie socially defined and maintained stimulus classes.

Use of differential reinforcement of other behavior during dyadic instruction to reduce stereotyped behavior of autistic students.

Effects of a differential reinforcement of other behavior procedure (DRO) on the stereotypic responses and task performance of 3 autistic students during dyadic instruction were examined. The procedures effectively reduced the stereotypic behavior of 2 children and substantially increased the task performance of the 2 lowest performing students. The procedure was unique because the time interval employed between potential opportunities for reinforcement for the absence of stereotypy was the natural length of one instructional trial delivered to a peer. Results were discussed in terms of models for intervention within task context and the usefulness of the procedure under natural teaching conditions.
