Abstract

Three experiments were conducted to find some factors which influence the processing of Kulca, the Hangul orthographic unit which corresponds to Korean syllable. In Experiment 1 and 2 pronunciation task was used. In Experiment 1, subjects took longer to pronounce the high frequency Kulcas than the low frequency Kulcas, whereas equivalent pronunciation latencies were obtained for Kulcas with Patchim (final consonant letter) and Kulcas without it. In Experiment 2, although the significant frequency effect of Kulca was replicated, the Kulcas containing very frequent nuclei (initial. consonant letter plus vowel letter) were pronounced faster than the Kulcas containing rarer nucle, This result .shows that Kulca nucleus plus Patchim units are used in pronouncing kulcas. In experiment 3 using same-different matching task, the psychological reality of the six types of Kulcas in their combination of consonant letters and a vowel letter was tested. The result suggests that both the presence of Patchim and the type of vowel letter are significant variables in the processing of Kulca type. Implications for possible models of Kulca processing are discussed.
