THE EFFECT OF ATTENTION ON THE SLOPE OF GENERALIZATION GRADIENTS,

Abstract

Forty-eight rats were given 100 rewarded trials with a single rectangle, and were then tested for generalization between this first rectangle and another differing from it either in brightness or in orientation. Thirty-two of the rats had received prior training either on a successive brightness or an orientation discrimination. The sixteen subjects who had received no prior training showed intermediate gradients of generalization. Of the pretrained subjects, those who were tested for generalization along the same dimension as their pretraining discrimination showed significantly steeper gradients, while those who were tested for generalization along the opposite dimension showed significantly less steep gradients.
