Two experiments were conducted to investigate the process of Korean letter perception. Slopes of letter detection latency in the conjunction condition, in which both the consonant and the vowel of letters had to be checked, matched the sum of slopes in the consonant target condition and the vowel target condition, in which either the consonant or the vowel, but not both, was needed to be checked. The result of Experiment 1 supported that Korean letters are perceived after integrating consonants and vowels that comprise each letter. To compare between the consonant precedence hypothesis and the vowel precedence hypothesis, number of letters that share the consonant with the target and number of letters that do not share the consonant with the target is manipulated in Experiment 2. Slopes of detection latency due to the number of letters that share the consonant were larger than that of letters that do not share the consonant. The result of Experiment 2 was interpreted to support the consonant precedence hypothesis.
