Abstract

Two experiments were conducted to examine how visual complexity and character structure influence Hangul perception. To this end, we manipulated visual complexity using a perimetric complexity metric and character structure in Experiment 1. We used only consonants as stimuli in Experiment 2. We implemented a trigram presentation method where participants were asked to report the presented trigram as accurately as possible. In Experiment 1, the results showed that accuracy rates in the simple visual complexity condition were higher that those in the complex condition, and that when visual complexity was controlled, the effect of character structure was significant such that the CV stimuli showed lower accuracy rates than the CVC stimuli did. In Experiment 2 where the trigrams consisted of only consonants demonstrated that overall accuracy was higher in Experiment 2 than Experiment 1, and that it was higher when the stimuli were presented in the right visual field relative to when they were in the left visual field. We discussed these results in relationship with findings in previous literature, especially with respect to the crucial role of visual complexity in perceptual processes in Korean.
