Behavior Therapy with High Level, Institutionalized, Retarded Adolescents.

The thesis of this paper is that instrumental, nonverbal behavior can be modified by a deliberate, repetitive, and systematic conditioning of verbal behavior according to experimentally established principles of learning. Verbal aggression or obnoxiousness, .when extinguished during therapy, will lead to the extinction of overt, motor aggression, since what a person does is reinforcing what he says. Two therapy cases are presented in support of this thesis. [ABSTRACT FROM AUTHOR]
