Escape as a factor in the aggressive behavior of two retarded children
Insights
Severely aggressive behavior in children can be an escape response. This escape-motivated aggression is controllable by using preferred reinforcers, strengthening alternative nonaggressive behaviors, or escape extinction procedures.
Area of Science:
- Behavioral Psychology
- Developmental Psychology
- Clinical Psychology
Background:
- Severely aggressive behavior in children presents significant challenges.
- Understanding the controlling variables of aggression is crucial for effective intervention.
Purpose of the Study:
- To identify variables controlling severely aggressive behavior in two children.
- To investigate the function of aggression as an escape response.
Main Methods:
- Experimental manipulation of demand and non-demand situations.
- Introduction of stimuli correlated with demand termination.
- Contingent reinforcement of correct responding and nonaggressive behavior.
- Manipulation of escape opportunities following aggressive and nonaggressive responses.
Main Results:
- Aggression was high in demand situations and low in non-demand situations.
- Aggression decreased significantly when escape from demands was possible or reinforced.
- Aggression increased when escape was permitted following aggressive behavior.
- Aggression was controlled by manipulating escape variables.
Conclusions:
- Aggression can function as an escape response.
- Escape-motivated aggression is controllable through environmental modifications.
- Interventions include using preferred reinforcers, strengthening alternative escape behaviors, and escape extinction.
Abstract:
This study sought to identify some of the variables controlling the severely aggressive behavior of two retarded children. In Experiment 1, each child was presented with several demand and nondemand situations. Aggression was frequent in the demand situations and rare in the nondemand situations. When a stimulus correlated with the termination of demands was introduced, aggression fell to a near zero level. In Experiment 2, for one child, a variety of preferred reinforcers was introduced into the demand situation contingent on correct responding. Aggression abruptly decreased to a low level. Experiments 3 and 4 involved the second child. In Experiment 3, this child was permitted, in one condition, to leave the demand situation if he emitted a nonaggressive response. Aggression decreased to a low level. In Experiment 4, he was prevented, in one condition, from leaving the demand situation in spite of high levels of aggression. Aggression fell to a near zero level. In Experiments 3 and 4, he was permitted, in several conditions, to leave the demand situation following aggressive behavior. Aggression increased to a high level. The results suggested that: (1) aggression can sometimes function as an escape response; and (2) escape-motivated aggression can be controlled by: (a) introducing strongly preferred reinforcers to attenuate the aversiveness of the demand situation; (b) strengthening an alternative, nonaggressive escape response; or (c) using an escape-extinction procedure.
