The effect of the valence and arousal of a word on the recognition after incidental learning

본 연구의 목적은 정서가와 각성가가 우연학습 후 기억 수행에 미치는 영향을 살펴보는 것이다. 이를 위하여 본 연구에서는 우연학습 패러다임을 이용하여 지각탐지와 어휘판단의 두 가지 처리수준에서의 과제 수행 이후 자극에 대한 재인에 정서가와 각성가가 각기 다르게 영향을 미치는지를 살펴보았다. 그 결과 과제의 처리수준에 관계없이 정서가가 부정적인 자극은 이후에 더 잘 재인되었으나 각성가가 높은 자극의 경우에는 그렇지 않은 경우보다 재인의 정확도가 낮았다. 이것은 정서의 두 차원인 정서가와 각성가가 서로 다른 양상으로 재인에 영향을 준다는 것을 의미하며, 기존의 선행연구들에서 부정적인 정서가 기억에 미치는 영향에 대해 상반된 결과들이 보고되는 이유가 인지수행에 서로 다른 방향으로 영향을 주는 정서가와 각성가를 동시에 고려하지 못했기 때문이라는 것을 시사한다.

Abstract

The purpose of this study was to examine the effect of the valence and arousal on the incidental learning tasks. Participants performed either one of the perceptual identification task and lexical decision task which are different in the level of processing. Later, a series of words were displayed and participants were asked to recognize whether or not each test word was shown when they performed a task. The results showed that, regardless of the tasks performed, words with negative valence were recognized better than those with neutral valence. Also, words with higher arousal level were recognized worse than those with lower arousal level. The results indicate the differential effects of the valence and arousal on cognitive processes. The results further suggests that the inconsistent findings across previous studies might be due to the failure of dissociating the influence of stimulus’ emotional valence and arousal level.
