Compared four groups of matched S s (40 each) in order to examine different subtest patterns of brain damage on the WAIS, using F‐tests and age mean profiles. The groups were: Normals, diffuse cortical degeneration, right and left hemisphere damage. The results indicated three patterns: (1) a normal pattern; (2) a diffuse degenerative and right hemisphere pattern; and (3) a left hemisphere pattern. The diffuse degenerative results were not significantly different from the right hemisphere results. The left hemisphere pattern had no large verbal vs. performance differences. These patterns appear to be produced by the interaction of three brain damage effects: (1) a general effects; (2) a right hemisphere effect; and (3) a left hemisphere effect. Verbal tests are both “hold” and left hemisphere tests, while three Performance Tests, are “don't hold” and right hemisphere tests. The WAIS requires other specific tests of brain damage for an adequate assessment of brain damage.
