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 meas ures are more sensitive to the effects of brain damage than are measur es from the Wechsler intelligence scales. This proposal was investigat ed in groups of 65 brain-damaged subjects and 45 nonbrain-damaged cont rols equated for age and level of education and subgroups of 34 brain- damaged subjects and 34 nonbrain-damaged controls closely matched on a ge and WAIS-R full Scale IQ. Differences on Halstead-Reitan measures f ound in the larger groups were not found in the subgroups matched on a ge and IQ. Further, discriminant analyses showed that 11 Halstead-Reit an measures were equivalent to the 11 WAIS-R subtests in discriminatin g brain-damage and nonbrain-damaged subjects. Thus, the proposal for p oorer sensitivity of the WAIS-R subtests was not supported.
