초록
본 연구에서는 시각적 요인에 따라 한글 단어 재인에 미치는 공간주의의 영향을 살펴보았다. 시각적 요인에 따라 공간주의의 영향이 다르게 나타나는지 살펴보기 위해 단어의 시각적 복잡성(실험 1)과 단어의 밝기 대비(실험 2)를 조작하였다. 단어의 복잡성에 따라 받침이 있는 조건과 받침이 없는 조건으로 나뉘었고, 단어의 대비에 따라 대비가 높은 조건과 대비가 낮은 조건으로 나뉘었다. 어휘판단과제를 사용하여 공간단서가 표적 위치에 주어지는 경우(타당 시행)와 표적 위치에 주어지지 않는 경우(비타당 시행) 간의 수행 차이를 단서효과로 계산하여 주의의 영향을 살펴보았다. 실험 결과, 단어의 복잡성에 따라서는 단서효과가 유사하게 나타났으므로, 공간주의의 영향은 복잡성에 의해 달라지지 않는 것으로 해석되었다. 단어의 대비에 따라서는 고대비 조건에 비해 저대비 조건에서 단서효과가 크게 나타났다. 대비가 낮을 때 공간주의의 영향이 더 커지는 것은 자극의 신호를 강화시키는 공간주의의 기제로 설명되었다.
Abstract
In this study, we examined the effects of spatial attention in Hangul word recognition depending on visual factors. The visual complexity of words (Experiment 1) and contrast (Experiment 2) were manipulated to examine whether the effect of spatial attention differs depending on visual quality. Participants responded to words with and without codas in experiment 1 and words in high-contrast and low-contrast conditions in experiment 2. The effects of spatial attention were investigated by calculating the difference in performance between the condition where spatial cues were given at the target location (valid trial) and the condition where the spatial cues were not given at the target location (invalid trial) as the cuing effects. As a result, the cuing effects were similar depending on the complexity of the words. It indicates that the effects of spatial attention were not different across the visual complexity conditions. The cuing effects were greater in the low-contrast condition than in the high-contrast condition. The greater effect of spatial attention when the contrast is low was explained as a mechanism of signal enhancement.
