거짓진술행동에서 나타나는 정서적 각성 및 인지적 부하

초록

The aim of this study was to investigate the effect of emotional arousal on lie detection with nonverbal behaviors. Lie (n=22) and truth (n=23) groups were performed group’s mission and then were interviewed with question (crime irrelevant, crime relevant) about the mission recording the emotional and cognitive cue with two cameras. The frequency of four cognitive cues and seven emotional cues were coded by two trained coders. The results revealed that lie group showed more cognitive load cue in crime-relevant question than crime irrelevant question while truth group did not show the differences between two question type for cognitive cue. Emotional cue were shown more in crime relevant question than crime irrelevant question regardless of the groups and there were no differences between the groups by question type. Classification rate based on emotional cue and cognitive cue showed that classification rate of cognitive cue was higher than the one of emotional cue (cognitive cue: 82.20, emotional cue: 57.20). This study imply cognitive load approach might have more advantage of classify liar and truth teller.
