초록
최근 연구들은 생존 맥락에서의 대상 기억이 다른 여러 맥락 조건들에서보다 더 정확함을 보고하고 있다(예, Nairne 등, [1]). 본 연구에서는 이러한 생존 맥락의 효과가 과제와 무관한 대상의 위치에 대한 기억에서도 나타나는지를 알아보고, 대상 위치 기억의 성차가 맥락에 따라 달라지는가를 살펴보고자 두 개의 실험을 진행하였다. 참가자들은 생존 맥락이나 혹은 이주 맥락 중 하나의 맥락 하에서 여러 위치에 순차적으로 제시된 사진(실험 1)이나 혹은 단어(실험 2)에 대한 맥락 적합도를 평가하는 과제를 수행한 후, 각 자극에 대한 회상 검사와 위치 기억 검사를 받았다. 실험 결과, 두 개의 실험 모두에서 생존 맥락 조건에서의 대상에 대한 회상율이 이주 맥락 조건에 비해 더 높은 것으로 나타났다. 위치 기억의 경우는 여성이 남성보다 더 좋은 것으로(실험 1), 그리고 생존 맥락에서 더 정확한 것으로(실험 2) 나타났으며, 자극의 종류 및 제시 방식에 따라 기억맥락 조건과 성별간의 상호작용 효과가 나타났다. 이 결과는 위치 기억에 있어서 기억의 부호화 맥락이 성별에 따라 다른 영향을 미치고 있음을 시사하는 것이다.
Abstract
Recent studies report that in terms of object memory, survival context has mnemonic advantage over other context conditions (e.g., Nairne et al, 2007). The present experiments explored whether this effect can also affect task-irreverent object location memory, and tested whether the context can change gender difference in object location memory. Participants were asked to rate the relevance of pictures presented at random locations (experiment 1) or words (experiment 2) under survival context or moving context. After rating the pictures or words, they answered recall test and location retrieval test. The results revealed higher accuracy in memory for objects encoded under survival context. Moreover, survival processing enhanced location memory, and the survival advantage in location memory emerged among woman.
