An experimental analysis of response acquisition and elimination with positive reinforcers.

An 11 year old retarded child with a history of deviant behaviors underwent an extensive experimental-therapeutic program. This habilitation program was an extensive effort to decrease deviant behavior and to increase appropriate behavior. The program provided an experimental analysis of omission procedures for the reduction of deviant behaviors, and positive reinforcement for the acquisition and maintenance of appropriate play behavior. Response covariation of deviant behaviors was demonstrated. The study included a time period when the child was physically ill and under medical isolation. At the end of a two year follow-up, the child had significantly advanced her overall behavioral repertoire thus improving her physical health and living conditions.
