Abstract: It has been found that sensation seeking is a robust predictor of risky driving behavior such as violations. Delay discounting refers to perceived reward value will decline as a function of time to get the reward increase. Delay discounting rate represents someone’s tendency to obtain immediate monetary reward or delayed larger reward. Given that risky driving behavior may associate with a trade off between immediate sensation satisfaction and delayed safety income, it is necessary to explore sensation seeking and delay discounting’s influence on risky driving at the same time. The aim of the present study is to investigate the relationship between people’s delay discounting rate to hypothetic monetary reward and their self-reported risky driving behaviors, as well as explore the possible moderate effect of delay discounting rate on the relationship between sensation seeking and risky driving. This study used internet questionnaire to collect data. 329 Chinese drivers completed Zukerman's Sensation-Seeking Scale (SSS), The Monetary Choice Questionnaire (MCQ) and Driver Behavior Questionnaire (DBQ). The results showed that (1) discounting rate to large magnitude of delayed money (80 CNY) could negatively predict ordinary violations, errors and total risky driving behaviors; (2) discounting rate to large magnitude of delayed money (80 CNY) could moderate the relationship between sensation seeking and risky driving. Specifically, sensation seeking’s influence on risky driving behavior happened only to people who revealed low discounting rate (tended to get immediate reward) but not to people who revealed high discounting rate was high (tended to get delayed but larger amount of reward). This study was the first study to discuss sensation seeking and delay discounting’s influence on risky driving at the same time. The study found that only to people who were tended to give up larger but delayed reward and choose immediate reward, their sensation seeking score could predict risky driving frequency. However, to people who tended to choose delayed larger reward, they may have a better consideration of long-term safety income thus giving up chase immediate sensation satisfaction, therefore their sensation seeking score couldn’t predict risky driving frequency. This study enriched the current theory frame and could be applied to select and train drivers and improve road safety.
