Abstract

Two experiments were conducted to determine the roles of phonological and orthographic codes involved in Hangul word recognition. Experiment 1 examined naming latencies for words and nonword as a function of the number of charaters (syllables) in the visually presented stimulus items, Words were named faster than nonwords. Latencies increased with the number of characters for both words and nonwords, However, the increasing rate for nonwords was much higher that that, for words, These findings suggest that words and nonwords are named through different processes, Experiment 2 measured lexical decision times for the same items used in Experiment 1, Mean response time (RT) for words was shorter than that for nonwords. Mean RT for nonwords with mare than two characters increased with the number of charaters in the items; however, mean RT for words did not, suggesting that words arid nonwords were differentially processed. It was concluded that, enven though Hangul is a phonologically shallow orthography, phonological code does not assume critical roles in Hangul ward recognition.
