Abstract

The self-stimulatory and social theories of self-destructive behavior of autistic, schizophrenic, and mentally retarded individuals were examined. The self-stimulatory theory states that self-destructive individuals obtain a form of sensory stimulation or reinforcement from the behavior itself. An extension of this theory, which is also presented in this paper, explains specifically how these individuals acquire sensory stimulation from such deviant behavior. By damaging the nerve structure of the skin, the tactile sensory threshold for physical input is lowered. This increase in the skin's sensitivity enables individuals to obtain sensory stimulation by repeatedly depressing the damaged area. In addition, I have proposed that the behavior may initially be a form of self-stimulation but subsequently may be operantly reinforced by the caretaker's concern for the individual.
