Theoretical Foundation of Halsted Reitan battery

There are really two theoretical bases for the Halsted Reitan battery, one contained in brain and intelligence and related writings of Halstead. The other are found in numerous papers and chapters written by Reitan and various collaborators. Halstead was really the first to establish a human neuropsychology laboratory in which patients were administered objective tests, some of which are semi-automated, utilising standard procedures and sets of instructions. His Chicago laboratory may have been the stimulus for the now common practice of administration of neuropsychological tests by trained technicians. Halstead was also the first to use sophisticated, multivariate statistics in the analysis of neuropsychological test data.
