Negative reinforcement plus edibles and praise produced about 90 percent correct responding for four severely retarded/autistic children (six to eight years old), while edibles and praise alone were much less effective. Use of negative reinforcement with noncompliant or difficult- to-motivate behaviorally disordered children appeared to be an…

The results showed that in each setting, overcorrection procedures were associated with statistically significant differences in the target behaviors. (Author/DLS)

Two studies involving five students (ages 9-17) with autism found that stereotypy was multiply determined or occurred across all assessment conditions (attention, demand, no-attention, and recreation conditions) and that the presumed association between response topography and behavioral function may be less important than previously realized.…

Results of a functional analysis of self-injurious behavior (SIB) in a 7-year-old child with autism showed that her SIB was maintained by access to preferred object and escape or avoidance of task demands. Warning stimuli in combination with extinction and noncontingent reinforcement reduced SIB to acceptable levels. (Author/CR)

After a brief review of the literature the research proposal focuses on the comparative effectiveness of non-verbal positive reinforcement vs. verbal negative reinforcement in the reduction of self-inflicted injury on 23 elementary age autistic children. In the two phase study each child would be paired by age, sex, length of time in school,…

Ten schizophrenic and autistic children who exhibited self destructive, tantrum, echolalic, and self stimulatory behaviors were treated by reinforcement therapy. Reinforcement withdrawal, in the form of interpersonal isolation contingent upon self-destruction, and electrical shocks served to extinguish these behaviors in some children.…

A description of the Social Exchange Laboratory's work with autistic children is presented. The laboratory's philosophy of the exchange theory of autism, seen as a set of habitual response patterns maintained and intensified by exchanges which are inadvertantly structured by others in the child's environment, is set forth with characteristics,…
