title: Unilateral brain lesions and MMPI performance: a preliminary study.
abstract: Samples of 15 Ss with right- and 20 Ss with left-hemisphere brain lesions secondary to war-related penetrating missile wounds were matched for age, education, and recency of injury and evaluated with the MMPI. Right-hemisphere lesioned Ss produced a composite profile with all scales within normal limits. In contrast, the composite profile of left-hemisphere lesioned Ss showed significant elevations on the Sc, D, and Hs clinical scales, suggesting increased psychopathological responses in such Ss. Although the general configurations of the composite MMPI profiles in the two samples were similar, significant differences in the elevation of both validity and clinical scales were obtained. The results tend to support previous findings of a depressive-catastrophic reaction in patients with lesions in the dominant hemisphere, while not supporting the euphoric-indifference response in nondominant-hemisphere lesioned Ss.
