Abstract
Normal hooded rats were superior to posterior operates on acquisition of a simultaneous brightness problem. Acquisition of a subsequent successive problem showed that operates had improved significantly but were still inferior to normals. Both normals and operates learned the simultaneous problem faster when a dark stimulus was the positive cue; however, free choice preference for the dark was demonstrated in normal Ss only. Effects of preference and perceptual factors on learning are discussed.
