Using video modeling to teach complex social sequences to children with autism

This study comprised of two experiments was designed to teach complex social sequences to children with autism. Experimental control was achieved by collecting data using means of within-system design methodology. Across a number of conditions children were taken to a room to view one of the four short videos of two people engaging in a simple sequence of activities. Then, each child’s behavior was assessed in the same room. Results showed that this video modeling procedure enhanced the social initiation skills of all children. It also facilitated reciprocal play engagement and imitative responding of a sequence of behaviors, in which social initiation was not included. These behavior changes generalized across peers and maintained after a 1- and 2-month follow-up period

Using video modeling and reinforcement to teach perspective-taking skills to children with autism.

We evaluated video modeling and reinforcement for teaching perspective-taking skills to 3 children with autism using a multiple baseline design. Video modeling and reinforcement were effective; however, only 2 children were able to pass an untrained task, indicating limited generalization. The findings suggest that video modeling may be an effective technology for teaching perspective taking if researchers can continue to develop strategies for enhancing the generalization of these new skills

RESTRICTED INTERESTS AND TEACHER PRESENTATION OF ITEMS

Restricted and repetitive behavior (RRB) is more pervasive, prevalent, frequent, and severe in individuals with autism spectrum disorders (ASDs) than in their typical peers. One subtype of RRB is restricted interests in items or activities, which is evident in the manner in which individuals engage with items (e.g., repetitious wheel spinning), the types of items or activities they select (e.g., preoccupation with a phone book), or the range of items or activities they select (i.e., narrow range of items). We sought to describe the relation between restricted interests and teacher presentation of items. Overall, we observed 5 teachers interacting with 2 pairs of students diagnosed with an ASD. Each pair included 1 student with restricted interests. During these observations, teachers were free to present any items from an array of 4 stimuli selected by experimenters. We recorded student responses to teacher presentation of items and analyzed the data to determine the relation between teacher presentation of items and the consequences for presentation provided by the students. Teacher presentation of items corresponded with differential responses provided by students with ASD, and those with restricted preferences experienced a narrower array of items

Using Obsessions as Reinforcers with and without Mild Reductive Procedures to Decrease Inappropriate Behaviors of Children with Autism

We assessed the effectiveness of using the obsessions of children with autism to reduce their inappropriate behaviors. Baseline consisted of a traditional differential reinforcement of other behaviors (DRO) in which food reinforcers were provided contingent upon a period of nonoccurrence of the inappropriate behaviors. Then, three treatment conditions were assessed using a multielement design. One condition provided objects of obsession as reinforcers for periods of nonoccurrence of the inappropriate behaviors. A second condition also provided the obsessions as reinforcers, but in conjunction with mild reductive procedures (verbal “no”, time-out). A final condition used the food reinforcers of baseline, but with mild reductive procedures. Results indicated that all three treatment conditions were more effective than the traditional food DRO of baseline. The most effective condition was the obsessions plus mild reductive procedures. Results are discussed in terms of recommendations for effective treatment planning
