Relative sensitivity of the WAIS-R subtests and selected HRNB measures to the effects of brain damage.
Reitan has argued that Halstead-Reitan Neuropsychological Battery measures are more sensitive to the effects of brain damage than are measures from the Wechsler intelligence scales. This proposal was investigated in groups of 65 brain-damaged subjects and 45 nonbrain-damaged controls equated for age and level of education and subgroups of 34 brain-damaged subjects and 34 nonbrain-damaged controls closely matched on age and WAIS-R full Scale IQ. Differences on Halstead-Reitan measures found in the larger groups were not found in the subgroups matched on age and IQ. Further, discriminant analyses showed that 11 Halstead-Reitan measures were equivalent to the 11 WAIS-R subtests in discriminating brain-damage and nonbrain-damaged subjects. Thus, the proposal for poorer sensitivity of the WAIS-R subtests was not supported.
