Abstract
Enucleated rats were tested for acquisition of a rough-smooth discrimination in which the front and back surfaces of a piece of sandpaper served as discriminanda. Either lesions or experimental manipulations were used to reduce the possibility of animals following potential somesthetic and/or olfactory cues from the abrasive surfaces. Results showed an olfactory-somesthetic confounding common to some earlier experiments.
