초록
본 연구는 공간-기반 주의(space-based attention)와 대상-기반 주의(object-based attention)가 공간 및 시각 작업기억에 미치는 영향을 살펴보고자 두 가지 주의 자원 양상이 모두 관여하는 공간 스트룹 과제를 이용하여 작업기억의 재인율을 측정하였다. 작업기억과 공간 스트룹 과제의 자극 배열의 유사성 조건은 작업기억 과제 수행 시 공간 시연에 미치는 공간-기반 주의의 영향을 살펴보고자 구성되었으며, 스트룹 조건은 작업기억 과제 수행시 대상에 대한 시연에 미치는 대상-기반 주의의 영향을 살펴보고자 하였다. 그 결과, 공간 작업기억과 공간 스트룹 과제의 자극 배열의 유사성이 높은 조건에서 공간 작업기억의 재인율이 높은 것으로 나타났으며, 스트룹 조건에 따라서는 차이가 없는 것으로 나타났다. 반면, 시각 작업기억의 재인율은 스트룹 일치조건보다 불일치조건에서 더 저조한 것으로 나타났으며, 유사성 조건에 따라서는 차이가 없는 것으로 나타났다. 이러한 결과는 작업기억에서 요구되는 자원의 양상과 선택적 주의 자원의 양상이 동일한 경우에만 선택적 주의가 작업기억에 영향을 준다는 것을 시사하는 것이다.
Abstract
This study investigated the effects of space- and object-based attention on spatial and visual working memory, by measuring recognition of working memory on the spatial Stroop task including two modalities of attention resource. The similarity condition of stimulus arrangement between working memory task and spatial stroop task was manipulated in order to examine the effects of space-based attention on spatial rehearsal during working memory task, while Stroop condition was manipulated in order to examine the effects of object-based attention on object rehearsal during working memory task. The results showed that in a condition that stimulus arrangement was highly similar for the spatial working memory task and the spatial Stroop task, recognition accuracy of the spatial working memory was high, but it was not significantly different with the Stroop conditions. In contrast, the recognition accuracy of visual working memory in the incongruent Stroop condition was lower than that in the congruent Stroop condition, but it was not significantly different with the similarity conditions (25% vs. 75%). The results indicated that selective attention has effects on working memory only when resource modality of working memory is the same as that of selective attention.
