Abstract
Positive practice overcorrection was effective in reducing stereotypic self-stimulatory behaviors displayed by retarded and autistic individuals; the procedure also may increase the occurrence of appropriate behavior through intensive practice. Several stereotypic and 1 appropriate behavior displayed by 2 autistic children were measured before and during treatment by a positive practice in appropriate toy play overcorrection procedure. Overcorrection was introduced for each of the targeted inappropriate behaviors in succession for both children. Overcorrection reduced all stereotypic behaviors displayed by both children; 1 subject displayed marked increases in the behavior practiced during overcorrection, appropriate toy play, relative to its baseline rate of occurrence. For some individuals, overcorrection may be effective in teaching and motivating appropriate forms of behavior as well as in reducing stereotypy.
