Social disruption of discriminated avoidance behavior

Animal Learning and Behavior Social Behavior


Two groups of rats were trained to respond on a discriminated avoidance schedule. For those animals that were initially trained together, escape rather than avoidance behavior occurred. Sexual mounting behavior and attack behavior were also observed. Those animals that were trained individually on the avoidance schedule seldom attacked when later paired with an unrestrained naive animal. Furthermore, the relative position of the naive animal in the chamber appeared to determine whether an avoidance or an escape response occurred. Disruption of discriminated avoidance responding appeared to be due not only to competing attack behavior, but also to the presence and position of the other animal in the chamber.
