Based on the principles of applied behavior analysis (ABA), discrete trial training (DTT) is used to develop a new response to a stimulus. DTT is based upon the principle of breaking down behavior into discrete steps called a "single teaching unit" or learning trials. Trials are repeated several times with the learner receiving…

This evidence-based practice overview on Structured Play Groups (SPG) includes the following components: (1) Overview: A quick summary of salient features of the practice, including what it is, who it can be used with, what skills it has been used with, and settings for instruction; (2) Evidence-base: The "SPG Evidence-base" details the…

This evidence-based practice overview on Parent Implemented Intervention (PII) includes the following components: (1) Overview: A quick summary of salient features of the practice, including what it is, who it can be used with, what skills it has been used with, and settings for instruction; (2) Evidence-base: The "PII Evidence-base"…

Introduction: The purpose of this study was to decrease the number of talk-outs displayed with a 3rd grade student with autism. She engaged in these behaviors during work time, specialty classes such as physical education, music and library, and group work. Method: A multiple baseline probe design was used to measure the effectiveness of…

Alternative reinforcement strategies on a differential reinforcement of low rates of behavior schedule resulted in significant reduction of self-stimulatory behavior of 9- and 11-year-old autistic boys. Efforts were made to match the sensory consequences derived from the reinforcement to those presumed to be maintaining the self-stimulatory…

Two short (20-second and 60-second) overcorrection procedures were effective in suppressing stereotypic behaviors of a 7- and a 12-year-old autistic student. (CL)

Results indicated that parents socially validated the effects of behavior therapy in that they judged the children as significantly improved after treatment, and that the effects of treatment were also socially validated by the parents' indication that they were more willing to interact with the children after treatment than before treatment.…

In a study of visual discrimination tasks with three autistic children (ages five-six), multiple sensory reinforcers maintained responding over more trials than did multiple edible reinforcers. Single sensory reinforcers and single edibles however, resulted in nearly equal numbers of trials to satiation. Sensory reinforcers produced higher…

Effects of sensory extinction procedures on nontargeted self-stimulatory behaviors of two autistic boys (7 and 12 years old) were assessed. In Experiment 1 application of sensory extinction for target behaviors resulted in decreased topographically similar behavior, but no change in dissimilar behavior. In Experiment 2, suppression also occurred…

Analysis of effects of intertrial intervals on correct responding and self-stimulatory behavior by four autistic children (6-11 years old) revealed that short intertrial intervals produced decreased levels of self-stimulation and increased levels of correct responding. (Author/CL)

When positive reinforcement was presented via teacher verbalizations in a noncontingent fixed-time schedule, two autistic children (six and nine years old) increased their percentage of correct responding on difficult and easy tasks. (Author/CL)

The article presents the case study of an autistic 12-year-old boy who was taught to increase the quality and decrease the size of his written letters. (PHR)

The study compared the efficacy and setting generalization of sensory extinction and overcorrection in suppressing self-stimulation in two autistic children (ages 7- and 12-years-old). Results indicated that sensory extinction significantly decreased self stimulation in the structured setting but did not generalize to other settings.…

A study examined the effectiveness of the Power Card Strategy in teaching sportsmanship skills to a 10-year-old girl with autism. The strategy incorporates special interests to teach and reinforce academic, behavior, and social skills. The strategy was effective in teaching sportsmanship skills and the behavioral generalized across multiple…

Noncontingent escape (NCE) was used to reduce disruptive behavior in three children (age 4) with autism during regularly scheduled speech therapy sessions. Results showed rapid decreases in disruptive behavior and accompanying increases in compliance across children. Findings suggest that speech therapists can effectively implement NCE. (Author/CR)
