Aggression and social experience in domesticated rats
Conducted an experiment with 48 male and 28 female Long-Evans rats. Small colonies were established, using adult Ss that had either received continuous social experience or had been isolated since weaning. Unfamiliar intruder rats-with or without postweaning social experience-were exposed individually to the colonies for a 21-hr period. Behavioral observations and an assessment of the intruder's physical condition indicated that serious fighting, physical injuries, and large weight losses occurred only when an isolation-reared intruder was placed into a colony of socially experienced Ss. Results demonstrate that aggression is a joint function of the rearing history of both the colony and the intruder and that social experience plays an important role in the behavioral development of this species.
