Abstract The Aachen Aphasia Test (AA T), originally developed as a test for aphasia language dis- orders in Germany, consists of six spontaneous speech rating scales and five subtests : Token Test, Repetition, Written Language, Confronting Naming and Comprehension. The study aimed to describe the linguistic properties of the AAT Thai version and to investigate the test perfor- mances of the normal subjects. In this study some problems of linguistic changes in the construc- tion of the Thai version were discussed. The results revealed that the normal subjects' perfor- mances on the test were independent of age, sex and education level. Therefore, the Thai version of AAT is applicable to the differential diagnosis of the communicative ablities of Thai aphasic patients.
