オノマトペの単語認知過程における表記形態の影響

抄録

The purpose of this study was to examine effects of orthography on word recognition process of onomatopeic words. Effect of orthography was examined by comparison between Hiragana and Katakana. Participants were requested to read 11 onomatopeic words that were presented by different orthography and to evaluate familiarity for orthography of onomatopoeic word. In reading task, We measured naming latency under two conditions (Immediate and Delayed), and compared it between Hiragana and Katakana. The results indicated, reading latency of Katakana was longer than it of Hiragana. On the other hand, familiarity for orthography showed no deviation between Hiragana and Katakana. That is, difference of orthography in onomatopeic words is not necessarily based on bias of familiarity. Effects of orthography in onomatopeic words may differ from the effects in the noun that has been previously reported. So, The effect of visual properties of orthography needs to be further examined.
