Efficacy of three projective techniques in differentiating brain damage among subjects with normal IQs

Obtained substantial differentiation between brain-damaged (N = 25) and non-brain-damaged (N = 25) groups of average intelligence with the WAIS, Rorschach and Hand Test. The use of projective tests in diagnosing neurological impairment was encouraged, but it was cautioned that brain damage and IQ are heavily interrleated, sometimes in complex ways, and that reliable signs of organicity may vary with the Ss level of intelligence.
