The subject was a 13-year-old boy manifesting delayed speech and learning disability including problems of reading and writing.
He was born after an uneventful pregnancy and delivery. In infancy, he had difficulty both in auditory comprehension and verbal output. In childhood, his academic achievement was poor and he had difficulty in reading and writing. During the first visit to our clinic, a discrepancy between verbal and performance IQ was recognized (V66 P 110 by WISC) .
He was unable to read and write Kana-letters accurately and also could not fully distinguish individual syllables from listened words. The subject could, however, acquire more words through Kanji-letters than Kana-letters. So Kanji-letters were thought to be a more successful tool in language acquisition in this case.
