The Halstead Category Test is a popular measure of abstraction, concept formation, and logical analysis skills. Due to its large apparatus, however, ease of administration of the standard Category Test is limited. For this reason, a number of computer versions of the Category Test have been developed to facilitate its administration. The current study evaluated the equivalence of a new computer version to the standard Category Test in a sample of undergraduate students. Analyses revealed that the two versions did not differ significantly on subtest error scores, total error scores, or Neuropsychological Deficit Scale scores. Results of the current study support the equivalence of this new computer version to the standard version of the Category Test.
