Abstract

The present study examined the role of spatial attention in implicit memory for words when the word identity processing was not required. Spatial attention to the identity-irrelevant perceptual features of the words was manipulated by using a visual search task (Experiment 1) or a focused attention task (Experiment 2). In two e experiments. a significant priming effect was not found for the target words as well as for the distractor words. Implicit memory for words was not affected by spatial attention on the perceptual properties of the words. indicating that the word identity processing is required to produce priming.

단어 정체확인 과정을 요구하지 않고 기억 과제와 무관한 단어의 지각적 특질에만 근거하여 공간적 주의를 할당하도록 하는 경우, 이러한 공간적 주의의 차이가 단어의 암묵기억에 미치는 영향을 두 개의 실험을 통하여 알아보았다. 실험 1에서는 독특한 색을 가진 표적자극의색을 판단하는 시각 탐색 과제를, 실험 2에서는 단서가 주어진 위치에 제시된 단어자극의 색을 판별하도록 하는 초점 주의 과제를 실시한후, 단어완성검사를 통하여 암묵기억을 측정하였다. 두 실험 결과, 방해자극뿐 아니라 표적자극에 대해서도 유의미한 점화효과가 관찰되지 않았다. 이는 기억 과제와 무관한 지각적 특질에 주의를 주는 것만으로는 단어에 대한 암묵기억 표상을 형성하기 어려우며, 단어에 대한 암묵기억 표상을 형성하기 위해서는 자극의 부호화 과정에서 단어 정채 확인 과정이 필요함을 시사한다.
