선행차량 추월에 대한 위험판단에서의 성별차이: 민감도, 반응편파 및 반응시간을 중심으로 = Gender Difference in Risk Perception for Overtaking: Focused on Sensitivity, Bias and Reaction Time

다국어 초록 (Multilingual Abstract)

Gender difference in risk perception for overtaking was explored with respect to sensitivity, response bias, and reaction time. The results showed the followings. First, although male drivers showed higher response sensitivity and more lenient response bias than female drivers in overtaking judgment in general. this difference was prominent in straight lane and slow driving speed conditions than in curved lane or fast driving speed condition. Second, female drivers tended to show slower overtaking judgment than male drivers, especially in the conditions of straight lane and slow driving speed. Third, female drivers' reaction time in miss and correct rejection was slower than male drivers. These results suggested the necessity of considering physical condition of overtaking situation as well as various dependent measures such as response sensitivity, response bias and reaction time in understand gender difference in overtaking judgment.

국문 초록 (Abstract)

본 연구에서는 선행차량 추월 상황에 대한 실험참가자들의 위험지각 양상을 성별에 따라 비교하였다. 추월상황은 도로유형과 운전속도 조건을 달리하여 동영상 형태로 제시하였고, 각 조건에서 관찰되는 실험참가자들의 반응민감도, 반응편파 및 반응시간을 종속측정치로 분석하였다. 본 연구의 주요 결과와 시사점을 요약하면 다음과 같다. 첫째, 추월판단에서의 민감도는 여성에 비해 남성이 더 높았고, 반응편파는 남성보다 여성의 경우 더 보수적으로 반응하는 경향이 관찰되었는데 이러한 차이는 운전속도가 느린 조건과 굴곡이 있는 도로에서 각각 더 두드러졌다. 둘째, 여성은 남성에 비해 직선도로보다는 굴곡이 있는 도로조건에서, 그리고 운전속도가 빠른 조건보다는 느린 조건에서 더 지연된 판단 반응시간을 보였다. 셋째, 여성은 남성에 비해 탈루와 정기각 반응을 더 느리게 결정하는 경향을 보였다. 본 연구의 결과들은 추월판단 과제에서의 성별 차이를 이해하기 위해서는 도로유형이나 운전속도와 같은 물리적 요인뿐만 아니라 운전자들의 판단정확도와 반응편파, 그리고 판단시간 등을 통합적으로 고려해야 한다는 것을 시사한다.
