An acquired-drive paradigm was employed. Seventy-two rats were divided into three groups with respect to the differences in treatment during ITIs in classical fear conditioning; rats of Group D were detained in shock compartment, rats of Group H were removed from the shock compartment but immediately returned to it, and rats of Group R were removed from the shock compartment and placed in the retaining box having different background and size. Group R learned a hurdle-jump response to escape a Tone-CS less than did Group D and H, while the difference between Group D and Group H was not significant. It was suggested that the infereior performance of Group R might have been due to the effect of placing the subjects in the retaining box different from the shock compartment during ITIs.
