title: Strain differences in rats with respect to speed of conflict resolution.
abstract: Speed of conflict resolution was studied in a conditioned punishment paradigm in a Skinner box and a straight runway. In both experimental situations speed of conflict resolution was defined as the latency to gain food during an approach-avoidance conflict. In the Skinner box Tryon Maze Bright rats were faster in speed of conflict resolution than Tryon Maze Dull rats, and Roman Low Avoidance rats were faster than Roman High Avoidance rats. In the runway situation, Wistar Kyoto rats were faster in solving the conflict than randomly bred Wistar Wu rats and Brown Norway rats were faster than Wistar Wu rats. Differences between the strains in speed of conflict resolution could not be consistently explained from strain differences in approach or avoidance behavior, measured separately. It is, therefore, suggested that speed of conflict resolution is a unique parameter.
