A large battery of reading related skills were orally administered to 111 4-year old and 118 5-year old Korean kindergartners, who were also tested on reading of regular and irregular Korean Hangul words. In regression equations, speeded naming was uniquely associated with reading of both regular and irregular words. In contrast, only the three measures of phonological awareness at the levels of phoneme onset, coda, and syllable uniquely explained Hangul regular word recognition, whereas only morphological awareness consistently explained irregular word recognition. Results suggest somewhat different cognitive demands for reading of regular and irregular words, based on the dual-route model, in Korean Hangul.
