Revised Token Test and Linguistic Errors Made by Aphasic Subjects

Abstract

We proposed the revised version of the Token Test as means of revealing linguistic and non-linguistic processing disorders of auditory comprehension in aphasics. The purpose of the modification was to assess information-processing abilities which rely primarily on the manupilation of linguistic rules.
We eliminated eight typical command patterns from the original version (DeRenzi & Vignolo, 1962), and decided to balance qualitation and quantitation of item and unit in the scoring system. The Revised Token Test was administered to 43 aphasic patients and the results were summarized as follows:
(1) In Part I-IV, the number of errors were reflected by attentional factors or sequencing span.
(2) In Part V-VIII, the errors showed a unsimilar pattern and grammatical aspects such as“left and right preposition”and“temporal order of events”were relatively sensitive to aphasic deficits.
(3) The Test performance was not able to discriminate among aphasic groups.
