거짓말 탐지상황에서 나타나는 용의자의 심리특성 연구

초록

The aim of the present study was to identify the psychological characteristics of suspects under lie detection situations. For this, the psychological characteristics between 157 ordinary people and 146 suspects were compared using scales which were measuring state/trait anxiety, shame/guilt, deceit/manipulation, and defensiveness. Additionally, to identify the difference according to existence of lying, this study divided suspects into lie and truth group and further analyzed differences of psychological characteristics between 2 groups. As a result, suspects showed significantly higher state anxiety, higher defensive tendency, and lower deceptive tendency than ordinary people, but there was no statistically significant differences of psychological characteristics between lie and truth group. This implies feeling higher anxiety and having positive impression management with high defensive and low deceptive tendency at the same time in suspects under lie detection situations. In addition, these results may predict that lie detection situations may not influence the results of lie detection test because suspects have similar psychological characteristics regardless of existence of lying.
