Abstract
The aim of this study was to analyze patterns and associations between written naming and dictation of Kanji and Kana words in aphasic patients. The subjects were 23 moderate and mild aphasics who showed dissociations among writing modalities. They were examined in 11 word-level language modalities, and experiments were undertaken on deblocking of writing prestimulated through good modalities. Four patterns of writing performance were found : dication was better than written naming ; Kanji was better than Kana ; Kana was better than Kanji ; and all writing modalities were poor. When a patient's performance in a target modality was not impaired severely and a prestimulation modality had close similarity to the target modality, then the facilitation rate was good. Similarity of output modalities, i. e., pointing, speech and writing, was more effective than that of input modalities in facilitation. Similarity of characters (Kanji or Kana) was also a factor of facilitation.
