Abstract
A case was reported of 27-year-old right-handed amnesic aphasia without speech-motor-disturbance. He could retrieve words by letter better than by voice. His retrieval ability was examined by detailed tests by voice and letter against commonly used objects in daily life, names of well-known areas in Japan and daily time orientations.
The major findings were as follows:
1) This case showed dissociation between retrieval by voice and retrieval by letter. He could retrieve the words by letter that could not retrieve by voice.
2) He could retrieve words by voice after the word retrieval by letter.
3) Different words were retrieved by voice and by letter.
