Abstract

This study was conducted to examine whether conceptual representational system was implicitly accessed while processing semantically similar but perceptually dissimilar pictures either conceptually or perceptually, The results indicated that the priming effects for the semantically similar picture pairs were found in conceptually driven processing but the effect was not found in data-driven processing. In addition. the semantic priming effect was found with 24 hour delay between the stimuli, The comparison of the recognition ratio and priming effects indicated that the priming effect was largely affected by semantically similar pictures. but recognition was relatively u unaffected, The results suggest that both Perceptual Representational System (PRS) and Conceptual Representational System (CRS) be involved during conceptually driven processing, but both PRS and CRS function independently during explicit recognition.

그림자극의 처리유형에 따라 의미적 표상체계에서의 점화효과에 차이가 나타나는지를 살펴보고자 지각적으로 상이하지만 의미적으로는 유사한 그림자극을 각각 자료주도적 처리와 개념주도적 처리를 하게 한 다음, 시간경과에 따른 점화 효과와 재인기억을 비교하였다. 실험결과, 자료주도적 처리를 하는 경우에는 의미적 유사자극의 점화효과가 나타나지 않았짐나, 개념주도적 처리를 하는 경우에는 의미적 유사자극의 점화효과가 나타나지 않았지만, 개념주도적 처리를 하는 경우에는 의미적 유사자극의 점화효과가 24시간까지 유지되는 것으로 나타났다. 재인기억검사와 점화효과를 비교한 결과, 의미적 유사자극이 암묵기억에 미치는 효과는 강력하지만, 외현기억에 미치는 효과는 거의 없는 것으로 나타났다. 이러한 결과들은 의미적 판단과제를 통한 개념주도적 처리 동안에는 지각적 표상체계와 의미적 표상체계 모두가 관여하지만, 의식적으로 기억표상체계를 탐색하여 정보를 인출하여야 하는 경우, 지각적 표상체계와 의미적 표상체계가 독립적으로 작용한다는 것을 시사한다.
