This study investigated the relationship between cognitive abilities and driving behaviour in situations of normal driving and hazardous driving. For driving behaviour, driving component skills were measured from two different types of driving situations such as normal driving situations and hazardous driving situations. Normal driving skills were evaluated through an on-street driving test, where search, speed control, and direction control were considered as driving component skills. Hazardous driving component skills were evaluated using a standardized video driving paradigm. Component skills that were evaluated in this paradigm were search, identify, predict, decide, and execute. A battery of predictive tests was administered to the participants. Forty-two students from high schools participated in this study. Analysis of multiple regression implied that the measure of dynamic visual signal perception introduced to this study could be used as a predictor of driving performance for both situations. Driving component skills showed different effects between normal situations and hazardous situations. (Author/publisher).
