THE DEVELOPMENT OF INSTRUCTIONAL CONTROL OVER CLASSROOM ACTIVITIES OF DEVIANT PRESCHOOOL CHILDREN1

Abstract

Differential reinforcement of compliance with teacher invitations to complete a specific academic task was applied to three extremely negativistic children in a special preschool class. For each child, this technique resulted in clear and useful increases in compliance as it was applied. In addition, the technique produced a greater diversity of sampling the available tasks by all children, enabling them to contact instructional materials they had previously avoided. The reinforcement system, contingent access to free playtime, materials, and a snack, mediated by a token, was thus demonstrated to be an effective contingency. In the case of two children whose compliance was not maximized by differential reinforcement alone, further increases in compliance were produced by combining a 1-min timeout for noncompliance with the differential reinforcement procedure.
