초록

The purpose of this study is to investigate the difference in P3 amplitude between relevant questions (RQ) and irrelevant questions (IRQ) during concealed information test using event-related potential. Response difference between guilty group, not-guilty but exposed to crime-related information group, and not-guilty and not exposed to crime-related information group are compared. A total of 126 subjects’ data has been analyzed out of 131 subject data. Data from 5 subjects has been discarded due to inadequacy. Ultimately, in each of the 3 groups, 42 participants are randomly assigned. Result indicated that the P3 amplitude observed in the Fz area showed a significant difference between the RQ and the IRQ among the guilty group. However, remaining groups of the two not-guilty groups did not show a significant difference in all areas of Fz, Pz, and Cz between the RQ and the IRQ regardless of the exposure of the crime-related question. The limitation and the implications are discussed in this article. (Korean J Str Res 2015;23:101∼107)
