Abstract
In this study brain-damaged Ss [subjects] were matched with normal controls and given a battery of tests which measured intelligence, perception and rigidity. The results can be summarized in 4 statements. Since intelligence was not more closely related to behavioral rigidity in the brain-damaged group than in the normal group, our results question the assumption that reduced intellectual functioning produces increased rigidity. Since perceptual ability was not highly correlated with behavioral rigidity in the brain-damaged group, rigidity does not appear to be a product of perceptual deterioration. Perceptual skills were not more closely related to intellectual abilities in the brain-damaged group than in the normal group. Although brain-damaged Ss behaved more rigidly than the normal controls, they did not regard themselves as being rigid.
