Abstract

The present study was designed to investigate the relationships between various neuropsychological deficits and patterns of personality variables. Fifty individuals with medically verified brain lesions had 8 tests administered as part of a larger neuropsychological assessment. Individual relationships between each of the 8 neuropsychological variables and each of the 13 clinical and validity scales of the MMPI were analyzed by means of t-tests and Pearson correlations. Multiple regression and discriminant analysis were used to assess complex relationships between the neuropsychological variables and the MMPI scales. Results of these procedures showed a relative lack of individual relationships between cognitive and personality variables, although there were strong correlations between patterns of personality variables and neuropsychological performance. Each neuropsychological deficit manifested a strong characteristic MMPI profile. Traditional personality differences associated with laterality of lesion were also replicated. Explanations for the various personological reactions were discussed in terms of etiology of brain damage, psychological reactivity and cognitive loss.
