Two experiments were conducted to examine the facilitatory effect of word length (the number of syllables in a word), a new phenomenon showing that bisyllabic words are recognized faster than monosyllabic words. In Experiment 1, three types of native Korean words were compared: monosyllabic words, bisyllabic simplex words, and bisyllabic compounds. The results showed that lexical decision was faster for bisyllabic words than monosyllabic words, confirming the facilitatory effect of word length in Korean. The word length effect was bigger for high frequency words than low frequency words. In Experiment 2 using Hanja words, the facilitatory word length effect was replicated, and the interaction of word length and frequency was found to be significant. The results of Experiment 1 and 2 were not consistent with the serial-parallel processing explanation and the ideal length hypothesis. An alternative explanation was attempted based on the properties of native Korean and Hanja words.
