초록
범죄자와 함께 범행 현장에 있었다는 사실만으로 용의자가 될 수도 있다는 가능성에 초점을 두고, 첫째, 범행관련 정보의 인식 유무에 따른 피험자 3집단(유죄, 인식있는 무죄, 인식없는 무죄)의 생리반응의 강도 차이를 둘째, 3가지 자극제시(질문법, 질문과 시각자극, 시각자극) 방법에 따른 생리반응의강도 차이를 셋째, 기존의 피부전도반응과 심장박동반응 지표와 더불어 심장박동변이도 중 하나의 지표인 LF/HF 지표와 뇌전도에서 분석한 알파파 좌우비대칭성, 베타파와 세타파가 폴리그래프 검사에서 거짓말 탐지의 유용한 지표로 사용될 수 있는가를 살펴보았다. 의무경찰 30명을 대상으로 거짓말탐지 검사를 실시하고, 반복측정 이원 변량분석과 각 반응의 차이를 상관 t 검증을 실시하였다. 그 결과, GSR, HR 지표에서 거짓말을 탐지하는 데 효과적임을 입증하였으며. 질문법, 질문과 시각자극, 시각자극에서유의미한 것으로 나타났다. 알파파 좌우대칭 지표는 GSR의 결과를 보충하는 자료로 사용될 수 있으며, 베타파 지표와 세타파 지표는 유·무죄집단을 변별하는데 활용될 수 있다. 끝으로 연구결과의 한계와 방향성의 제언을 덧붙였다.
Abstract
Focused on the possibility that the presence of a person at the crime scene with the criminal(s) could make him(her) the suspect, three parameters were evaluated as a potential indicator of the polygraph to detect lies. First, the differences in the strength of the physiological responses based on the recognition or un-recognition of the presence of crime-related information by subjects which were divided into three groups (guilty, innocent recognized, does not recognize the innocence) were evaluated. Second, a physiological difference in the strength of the reaction by three stimuli (Questions, questions and visual stimulation, visual stimulation) was tested. Third, the asymmetric analysis of alfa-wave with skin conduction response, a heart rate response indicators from one of the indicators of heart rate variability and LF/HF index electroencephalograms, beta waves and theta waves were evaluated. Polygraph examination was given to 30 participants duty police officers, and the difference of the two-way ANOVA with repeatedly measured responses correlated t-test was conducted. As a result, visual stimulation, GSR and HR indicators were proved to be effective to detect lies. The GSR and HR indicators can be used to detect lies. Three stimuli (Questions, questions and visual stimulation, visual stimulation) was shown to be helpful to detect lies. The symmetrical Alfa waves could be used to supplement the GSR data. The beta waves and theta waves indicators can be used to discriminate a group of innocent existence. Finally, the limitations of the study and the future direction of current related research were discussed.
