The effect of unilateral brain lesion on reasoning.
The results of the Four Card Problem and those of Perceptual Tests were compared in order to tease out the relevance of a "perceptual classification" deficit on reasoning. The prediction that right hemisphere brain lesions would facilitate insight into the problem was upheld. In addition all patients who had a specific perceptual classification deficit solved the problem.
