| Abstract: | A significant reduction (p < .05) in the frequency of aggressive behaviour below baseline was found with eight institutionalized mentally retarded adult males using a systems intervention procedure. Self‐charting, a token system, differential reinforcement of other behaviour, verbal and physical prompts, restraint, time out from reinforcement, seclusion, and teaching alternatives were systematically applied with staff response options being contingent on the degree of control exhibited by the subject. Although it was concluded that this is an effective treatment model, further research was suggested. |
