The shuttle-avoidance response chains of rats

Abstract

Three female hooded rats received free-operant avoidance training that incorporated a shuttle requirement, The rats' activities during the final portions of Sessions 5, 10, and 15 were systematically analyzed. The rats showed minimal within-and between-subject differences in their shuttle-avoidance response chains: They walked across and beyond the midline, paused, turned, and again walked across and beyond the midline. Comparisons between shuttle-and leverpressavoidance response chains are offered.
