| Abstract: | This study examined the extent to which mora deletion (phonological analysis), nonword repetition (phonological memory), rapid
automatized naming (RAN), and visual search abilities predict reading in Japanese kindergartners and first graders. Analogous
abilities have been identified as important predictors of reading skills in alphabetic languages like English. In contrast
to English, which is based on grapheme-phoneme relationships, the primary components of Japanese orthography are two syllabaries—hiragana
and katakana (collectively termed “kana”)—and a system of morphosyllabic symbols (kanji). Three RAN tasks (numbers, objects,
syllabary symbols hiragana]) were used with kindergartners, with an additional kanji RAN task included for first graders.
Reading measures included accuracy and speed of passage reading for kindergartners and first graders, and reading comprehension
for first graders. In kindergartners, hiragana RAN and number RAN were the only significant predictors of reading accuracy
and speed. In first graders, kanji RAN and hiragana RAN predicted reading speed, whereas accuracy was predicted by mora deletion.
Reading comprehension was predicted by kanji RAN, mora deletion, and nonword repetition. Although number RAN did not contribute
unique variance to any reading measure, it correlated highly with kanji RAN. Implications of these findings for research and
practice are discussed. |
