본 연구는 이해득실 상황에 따라 거짓말 탐지에 대한 주관적 지표들이 달라지는지, 그리고 대학생, 교도관, 재소자들의 세 집단을 대상으로 거짓말 탐지에 대한 주관적 지표가 서로 차이가 있는지를 밝혀 보고자 하였다. 또한, 본 연구에서 밝혀진 거짓말 탐지에 대한 주관적 지표와 선행 연구결과에서 나타난 객관적 지표 사이에 어떤 차이가 있는지를 알아보고자 하였다. 이를 위해서, 대학생(198명), 교도관(132명), 재소자(186명)들에게 연구자가 설정한 높은 이해득실 상황과 낮은 이해득실 상황에서 타인들이 거짓말을 하는 경우, 21개 언어․비언어적 특징들이 평상시와 비교해서 어떤 변화를 나타낼 것인지를 7점 척도로 평정하게 하였다. 그 결과, 이해득실 상황에 따라 거짓말 탐지에 대한 주관적 지표가 달라지지 않았고, 집단 간에도 서로 유사한 것으로 나타났다. 즉, 이해득실 상황이나 집단과 관계없이, 언어적 단서는 신뢰롭게 보이려고 하는 반응, 비언어적 단서는 불안함을 나타내는 반응과 관련된 단서들이 거짓말 탐지에 대한 주관적 지표로 나타났다. 또한, 거짓말 탐지에 대한 주관적 지표와 객관적 지표는 말주저, 시선회피, 몸 움직임 등에서 서로 일치하는 것으로 나타났으나, 나머지 18개 단서에서는 서로 다른 것으로 나타나, 거짓말 탐지에 대한 주관적 지표를 토대로 타인의 거짓말을 탐지하는 것은 부정확한 결과를 초래할 것으로 예상된다.
Purposes of this study was as following; What differences do subjective indicators of deception detection according to high and low stake situations? Does groups difference appear in beliefs about deception cues? Is what differences between objective indicators and subjective indicators of deceptions? Participants of this study were consisted of university students, prison officers, prisoners. They completed a questionnaire concerning beliefs about 21 verbal and nonverbal behaviours in high/low-stake situations. For each behaviour, they were asked to rate on a seven-point scale how are these behaviours changed comparing to normal times. The results were that subjective indicators of deception were no differences between high-stake and low-stake situations, and no differences among groups. Also, it appeared that the subjective indicators of deception were substantly different from the objective indicators of deception.
