Abstract
Intradimensional (ID) and extradimensional (ED) shifts were compared using rats as subjects. By counterbalancing with respect to the positive cue in the shift task, it was possible to determine whether ID subjects were facilitated by favorable generalization of the instrumental response that was acquired in original learning. The results confirmed the superiority of the ID over the ED shift, previously reported by Shepp and Eimas (1964), and there was no significant evidence of differential generalization of the instrumental response. It is concluded that the Shepp and Eimas results were replicated and that the ID superiority cannot be accounted for solely in terms of favorable generalization of the instrumental response.
