외상 관련 DRM 목록의 개발 = Development of Trauma-related DRM Lists

다국어 초록 (Multilingual Abstract)

In the Deese-Roediger-McDermott(DRM) paradigm(Deese, 1959; Roediger & McDermott, 1995), participants are asked to learn several semantically associated word lists, to recall each list immediately after its presentation, and to recognize list words. On both recall and recognition tasks, participants often falsely recall and/or recognize “critical lures”; nonpresented words semantically associated with each list. Recently, several studies have used the DRM paradigm with trauma survivors, to clarify the features of traumatic memory. The purpose of this study was to develop trauma-related DRM lists and to provide initial benchmark data for future studies of post-traumatic stress disorder(PTSD) and false memories. Using forward and backward association methods, 10-word lists were developed around these critical lures: suicide, kidnap, fire, war, funeral, traffic accident, rape, and blood. Then, a DRM paradigm using these lists was administered to 81 college students. The results showed that participants mistakenly claimed the critical lures had been presented with frequencies of 3.7-25.9% on recall and 13.6-70.4% on recognition. These data will serve as a useful benchmark for designing experiments about false memories in PTSD patients. Limitations of the current study and implications for future research were discussed.

Deese-Roediger-McDermott(DRM) 패러다임(Deese, 1959; Roediger & McDermott, 1995)은 피험자에게 결정적 유인단어와 가장 의미적으로 가까운 연합단어들로 이루어진 목록을 학습시키면 목록에 포함되지 않은 결정적 유인단어에 대한 잘못된 회상과 재인이 일어남을 보여주는 실험 절차로, 최근 외상 생존자에게 DRM 패러다임을 적용함으로써 외상적 기억의 본질을 밝히고자 한 몇몇 시도가 있었다. 본 연구는 외상 생존자의 오기억과 정보처리과정을 밝히기 위한 예비 연구로, 외상 단어에 대한 DRM 목록을 개발하는 것이 그 목적이다. 본 연구에서 forward 및 backward 연상방식을 사용하여 각 10개의 단어들로 구성된 8세트의 외상 관련 DRM 목록을 구성하였는데, 각 목록의 결정적 유인단어는 다음과 같다: 자살, 유괴, 화재, 전쟁, 장례식, 교통사고, 강간 및 피. 81명의 대학생을 대상으로 DRM 절차를 사용하여 실험을 실시한 결과, 각 단어 세트별로 피험자의 3.7-25.9%가 오회상을 보였고 13.6-70.4%가 오재인을 나타내었다. 본 연구에서 개발된 외상 관련 DRM 목록은 향후 외상 후 스트레스 장애 환자들의 오기억 연구에 유용하게 활용될 수 있을 것이라 기대된다. 본 연구의 제한점과 향후 연구에 대한 함의가 논의되었다.
