초록

자극의 정서가가 전역/국지처리에서 시각적 주의범위에 미치는 영향을 밝히기 위해 두 가지 실험을 수행하였다. 첫 번째 실험에서는 전역/국지처리에서 전역 선행성과 국지 선행성을 보이는 자극 조건을 확인하기 위해 국지자극의 밀집성을 변화시켜 고밀도와 저밀도조건으로 구분하고, 각 조건에서 전역/국지처리의 반응 특성을 조사하였다. 연구 결과, 고밀도조건에서는 전역 선행성이, 저밀도조건에서는 국지 선행성이 관찰되었다. 두 번째 실험에서는 전역/국지형태를 제시하기 전에 정서자극을 제시하여, 선행하는 정서자극이 전역/국지처리에 미치는 영향을 조사하였다. 연구 결과, 자극의 정서가에 따라 전역/국지처리에 미치는 영향이 달랐는데, 고밀도조건에서는 긍정자극과 중립자극의 전역 선행성이, 저밀도조건에서는 부정자극의 국지 선행성이 관찰되었다. 이는 긍정정서와 부정정서의 주의범위가 상이함을 시사하는 결과로, 긍정자극의 주의범위 확장과 부정자극의 주의범위 축소를 반영하는 것이다.

Abstract

We investigated whether emotional valence has an effect on visual attentional scope in global/local processing task. We presented hierarchical stimuli with different number of elements and different inter-element distances at local scale. The global/local compatibility effect relied on the sparsity of local stimuli (Experiment 1). Low sparsity stimuli (high density) elicited global precedence, and high sparsity (low density) stimuli elicited local precedence. Global and local precedence of global/local compatibility effect also relied on a leading emotional valence (Experiment 2). The global precedence effect was found for positive and neutral target, and the local precedence effect was found for negative target. These results suggest that the visual attentional scope is influenced by emotional valence. In other words, positive emotion broadened the scope of attention, and negative emotion narrowed the scope of attention.
