The Halstead–Reitan Neuropsychological Test Battery (HRNB) and allied procedures is a comprehensive suite of neuropsychological tests used to assess the condition and functioning of the brain, including etiology, type (diffuse vs. specific), localization and lateralization of brain injury.Walsh, K.W.

New York: Academic Press A major aim of administering the HRNB to patients was if possible to lateralize a lesion to either the left or right cerebral hemisphere by comparing the functioning on both sides of the body on a variety of tests such as the Suppression or Sensory Imperception Test, the Finger Agnosia Test, Finger Tip Writing, the Finger Tapping Test, and the Tactual Performance Test.Russell, E.W., Neuringer, C., & Goldstein, G. (1970). Assessment of Brain Damage: A Neuropsychological Key Approach. New York: Wiley-Interscience. One difficulty with the HRNB was its excessive administration time (up to three hours or more in some brain-injured patients). In particular, administration of the Halstead Category Test was lengthy,Steindl, S.R., & Boyle, G.J. (1995).

Demographic norming

Raw scores on the Halstead–Reitan Neuropsychological Battery are typically converted to demographically corrected scores using normative datasets that adjust for variables such as age, education, sex, and, in some cases, race or ethnicity. Demographically corrected T-scores are used clinically to flag performance below expectations relative to a reference group rather than relative to the unstratified population.

The use of race as a normative variable has been the subject of long-running debate in clinical neuropsychology. The original justification was that race-stratified norms reduce the risk of overdiagnosing cognitive impairment in groups historically subject to overpathologizing. Criticism of the practice includes the contention that race-based norming treats a socially defined category as a biological proxy and may either mask or exaggerate cognitive impairment depending on the direction of the adjustment, and that observed group differences in test performance are better attributed to educational quality, language, acculturation, and the cumulative effects of structural inequity than to any inherent group characteristic. Performance-based and regression-based scoring approaches have been proposed as alternatives to race-stratified norms.
