Abstract

Using mental rotation paradigm, the present study examined underlying mechanisms of how Korean words are being processed. In Experiment 1, by varying visual complexity of words using 2- to 4-character words, mono-syllabic words wers rotated and presented from various angles at random and lexical decision times were compared. The results showed that regardless of lexicality and the degree of rotation, words of fewer characters were decided faster. This evidence supports the argument that mono-syllabic Korean words are being processed in a piecemeal fashion. In Experiment 2, same tasks were given to the subjects with words of 2- to 4-syllables. Here, words that contained more syllables took longer to decide. This finding was similar with the first experiment supporting piecemeal type processing of multi-syllabic Korean words. Previous research have argued that size of mental image to be processed can also influence decision times in spatial tasks such as mental rotation. To exclude the possibilty of such a factor, Experiment 3 controlled visual angle of 3- and 4-syllabic words by varying the physical size of each syllable. Still, the latency pattern was comparable to that of Experiment 2 which supports an analog-type processing in Korean words. Directions of further research and limitations of the present work were also discussed.
