SLTA(Standard Language Test of Aphasia)was administered to a total of 313 aphasic subjects and the test records were analyzed by means of factor analysis and scalogram analysis. Factor analysis gave a simple structure which allowed a classification of test variables into three groups representing three language modalities; group A of writing, group B of speech and group C of comprehension. Separate scalogram analyses of these groups A, B and C revealed an almost ideal unidimensionality for scaling in respective groups. Distribution of the subjects was displayed by three axes of comprehension, speech and writing corresponding to three edges of a cuboid. The subjects were laid along the three edges, jointing each other to form a“gzigzag way”in the cuboid. Thus an ordering of comprehension, speech and writing, from severe impairment to mild, was found along the“zigzag way”which represented a continuous3-dimension structure.
