A COMPARISON OF PROCEDURES FOR ELIMINATING SELF‐INJURIOUS BEHAVIOR OF RETARDED ADOLESCENTS¹

An attempt was made to eliminate the self-injurious behaviors of four institutionalized, profoundly retarded adolescents. Some of the behaviors studied were: face-slapping, face-banging, hair-pulling, face-scratching, and finger-biting. Three remediative approaches to self-injurious behavior were compared. Elimination of all social consequences of the self-injurious behavior was not effective with the two subjects with whom it was attempted. The same two subjects were exposed to a procedure involving reinforcement of non-self-injurious behavior which was ineffective under no food deprivation and was effective with one of the two subjects under mild food deprivation. Electric-shock punishment eliminated the self-injurious behaviors of all four subjects with whom it was attempted. The results suggested that punishment was more effective than differential reinforcement of non-self-injurious behavior which, in turn, was more effective than extinction through elimination of social consequences. However, the effects of the punishment were usually specific to the setting in which it was administered. In order to eliminate the self-injurious behaviors of severely retarded children, it is apparently necessary to carry out the treatment in many of the settings in which it occurs.
