Abstract
Three groups of albino rats (N=12 Ss per group) received 72 escape training trials in a hurdle-jumping apparatus, with shock presentation on 33%, 66%, or 100% of the trials, followed by 72 extinction trials. Performance during acquisition was directly related to percentage of shock presentation (p <.001); performance during extinction, in terms of relative scores, demonstrated the PRE (p <.01).
