The purpose of this study was to assess the clinical applicability of a form of aphasia test, the Korean Test Form 1, which is adapted for use in Korea from the test for Differential Diagnosis of Aphasia (The Roken Test) in Japan. The Korean Test Form 1 was applied to 40 aphasics and 40 normal controls, and the following results were obtained: 1. The aphasic group showed significantly low mean score in every subtests as well as total scores compared with the normal controls. 2. There was a tendency for relatively higher scores in the subtests of numbers and calculation than those of speech performance in patients with aphasia. 3. The types of aphasia were determined in 34 (85%) of 40 aphasics by the Korean Test Form 1 : showing 5 persons with amnestic aphasia, 7 with Broca's aphasia, 15 with Wernicke's aphasia and 7 with global aphasia. Therefore, we concluded that this Korean Test Form 1 would be clinically valuable for the differential diagnosis and the classification of aphasia in Korea.
