The study aimed to examine similarities among three auditory comprehension tests. The three tests are 1) Standard Language Test of Aphasia (Subtes of auditory comprehension) (S-test), 2) Token Test (T-test) and 3) Syntax Test of Aphasia(Subtes of auditory comprehension) (A-test). 48 right-handed, aphasics were tested, Cluster analysis was performed. Analysis of the results obtained two clearly defined clusters and one non-clustered item. The first cluster was composed of word comprehension items, namely, the word comprehension items of S-test, part A of T-test and level 1 of A-test. The second cluster was composed of T-test items except part A. The motcluster item consisted of the sentence comprehension items of the S-test, the article manupilation items of the S-test, and all items of the S-test except level 1. The results suggest that each test has its own character ; further careful analysis is required before one test can be used as a substitute for the others.
