Abstract

Previous research has shown that aversive stimulation causes aggression in several lower species of mammals prior to any specific conditioning. Our results show that fighting in response to shock tends to persist in spite of negative reinforcement for other behavior. The frequency of shock-induced fights decreased significantly only when the reinforcement of shock termination was made contingent upon a specific nonaggressive response.
