Abstract
Sixty albino rats with unilateral lesions of striate cortex, unilateral orbital enucleations, or sham operations were trained on black-white and horizontal-vertical discriminations, with order of problem presentation counterbalanced. Mastery of the initially acquired discrimination greatly enhanced acquisition of the second; however, the previously 4 reported enhancement of acquisition associated with unilateral striate ablation proved to be of limited generality: it occurred only during initial learning of the horizontal-vertical problem.
