Application of four Wechsler indices of mental deterioration to 95 cases of known head-injured Ss indicates that there are between index differences but that except for the Wechsler Revised index, locus of injury does not affect the efficiency of the indices. The findings were explained on the basis that trauma to the head results in two broad and measurable psychological effects: (1) generalized impairment of concentration and attention and (2), depending upon locus of injury, additional impairments of selective coping skills. In this study, a mixed parietal injury appears associated with deficient conceptualization skills either verbal or motor.
