Previous studies have shown that male drivers drive faster than female drivers, but there is no agreement on whether impulsivity could induce this sex difference, nor is there a cross-sectional comparison of the effects of different road environments. The purpose of this study was to verify whether impulsivity and impulse control could explain the sex differences in driving speed. A driving simulator study (study 1, N = 41) was performed to investigate whether there were sex differences in driving speeds in two road sections of different complexity, and a questionnaire survey (study 2, N = 163) was conducted to investigate the relationship between sex, impulsivity, impulse control and driving behavior of the participants. The results showed that male drivers drove faster on simple roads, but this difference did not show on complex roads. There were no sex differences in impulsivity traits, but male participants had significant lower levels of impulse control. The results also reveal a partial mediating role of impulse control in the relationship between sex and driving speed. These results suggest that impulse control can predict dangerous driving behaviors and is an important factor in explaining sex differences in driving speed.
先前的研究表明男性驾驶员比女性驾驶员开车速度更快，但对于冲动是否会导致这种性别差异，以及不同道路环境的影响是否存在横断面比较，尚无定论。本研究旨在验证冲动和冲动控制是否可以解释驾驶速度的性别差异。通过驾驶模拟器研究（研究 1，N=41）来研究在两个不同复杂程度的道路路段中是否存在驾驶速度的性别差异，同时通过问卷调查（研究 2，N=163）来研究参与者的性别、冲动性、冲动控制和驾驶行为之间的关系。结果表明，男性驾驶员在简单道路上的行驶速度更快，但在复杂道路上没有这种差异。冲动特质方面没有性别差异，但男性参与者的冲动控制水平显著较低。研究结果还揭示了冲动控制在性别与驾驶速度之间关系中的部分中介作用。这些结果表明，冲动控制可以预测危险驾驶行为，是解释驾驶速度性别差异的重要因素。
