Physical restraint as positive reinforcement.

The reinforcing function of physical restraint was analyzed for three retarded individuals who had a history of restraint and appeared to enjoy it. Using a preference paradigm with one participant and a reversal design with two others, we found that an arbitrary response systematically increased for each participant when followed by brief periods of restraint. No comparable increases occurred in conditions in which responses were not reinforced or were followed by stimuli designed to control for the nonrestraint components of the restraint consequence. Results were discussed in terms of three clinical issues: determining the possible role of restraint in maintaining behavior problems such as self-injury in natural settings, preventing or eliminating the reinforcing function of restraint, and using restraint reinforcement in treating behavior problems when this consequence is the only identifiable reinforcer for an individual.
