Abstract

Previous studies on fear of crime used survey and interview to measure fear of crime. However, though these methods can measure fear of crime in past events, they cannot measure real time fear of crime. In this paper, we use EEG to measure fear of crime in real time. We measure and analyze the EEG of subjects watching the video and confirm the difference between three groups classified according to the degree of fear of crime. As a result, about two times more beta waves are shown when a group of subjects with a high degree of fear of crime watches the images of fear of crime and 1.5 times more beta waves are shown among the other groups. Although watching videos related to the crime increased the beta waves, the police video showed little increase in beta waves because the subjects can sense safety in the video even if it is related to crime.

기존 연구에서는 범죄에 대한 두려움을 조사하기 위해 설문조사와 인터뷰를 사용하였다. 그러나 설문과 인터뷰를 이용한 방법은 과거 사건에 대한 범죄에 대한 두려움을 측정할 수 있을 뿐 현재 인지하는 범죄에 대한 두려움을 실시간으로 측정하지 못한다. 본 논문에서는 이를 해결하기 위해 뇌파를 사용하여 범죄에 대한 두려움을 측정한다. 영상을 시청하는 연구대상자의 뇌파를 측정하고 분석하고, 연구대상자를 범죄에 대한 두려움 인지 정도에 따라 세 그룹으로 분류하여 각 그룹간의 차이를 확인한다. 그 결과, 범죄에 대한 두려움 인지 정도가 높은 그룹의 피험자가 범죄에 대한 두려움 영상을 시청할 때 약 2배 더 많은 베타파가 나타나고, 다른 그룹의 피험자들은 약 1.5배 더 많은 베타파가 나타난다. 범죄와 관련이 있는 영상은 모두 베타파가 증가하였지만, 경찰출동 영상은 적은 증가를 보였다. 이는 범죄와 관련이 있는 영상이라도 안전함을 인지하기 때문에 베타파가 적게 증가한다.
