초록

본 연구는 한글 자극의 시각적 복잡도와 글자 구성이 한글 자극 탐지에 어떤 영향을 미치는지를 알아보고자 수행되었다. 이를 위해서 본 연구는 실험 1에서 외곽 복잡도를 이용하여 시각적 복잡도를 조작하였고, 글자의 자모 구성을 조작하여 자음+모음(CV)과 자음+모음+자음(CVC) 두 개의 수준을 가졌다. 실험 2에서는 자음으로만 이루어진 자극을 사용하였다. 두 실험 모두 세 글자 과제를 사용하였는데, 이때 실험 참가자들은 주어진 세 글자 자극을 최대한 정확하게 보고하여야 했다. 실험 1의 결과, 시각적으로 단순한 자극이 복잡한 자극에 비해 유의미하게 높은 탐지율과 넓은 시각 폭을 보였다. 또한 시각적 복잡도가 통제된 경우에는 글자 구성의 효과가 유의미하게 나타났는데, CV자극의 탐지율이 CVC자극에 비해 낮았다. 실험 2는 자음으로만 이루어진 자극을 제시하였는데, 전반적인 탐지율이 실험 1에 비해 높았고, 좌시야에 비해 우시야에 제시된 자극의 탐지율이 높은 것을 관찰할 수 있었다. 이러한 결과를 통해 선행 연구와의 관련성을 논의하였고, 특히 한글 지각과정에서의 시각적 복잡도의 중요성에 대한 논의가 이루어졌다.

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.
