Although there are clear moral components to traffic violations and risky and aggressive driving behavior, few studies have examined the relationship between moral values and risky driving. This study aimed to examine the relationship between moral views of driving behavior and brain activity. Twenty healthy drivers participated in this study. A questionnaire regarding their moral values concerning driving behavior was administered to the participants. Brain activity was measured using near-infrared spectroscopy while eliciting moral emotions. Based on the results of the questionnaire, the participants were divided into two groups: one with high moral values and the other with low moral values. Brain activity was statistically compared between the two groups. Both groups had significantly lower activity in the prefrontal cortex during the self-risky driving task. The low moral group had significantly lower activity in the left dorsolateral prefrontal cortex than the high moral group, while it had lower activity in the right dorsolateral prefrontal cortex in the self-risky driving task than in the safe driving task. Regardless of their moral values, the participants were less susceptible to moral emotions during risky driving. Furthermore, our findings suggest that drivers with lower moral values may be even less susceptible to moral emotions.
虽然交通违规以及危险和激进的驾驶行为中存在明确的道德成分，但很少有研究考察道德价值观与危险驾驶之间的关系。本研究旨在探讨对驾驶行为的道德看法与大脑活动之间的关系。20名健康驾驶员参与了本研究。向参与者发放了一份关于他们对驾驶行为的道德价值观的问卷。在引发道德情绪时，使用近红外光谱法测量大脑活动。根据问卷结果，将参与者分为两组：一组具有高道德价值观，另一组具有低道德价值观。对两组之间的大脑活动进行了统计学比较。在自我危险驾驶任务期间，两组的前额叶皮质活动均显著降低。低道德组在自我危险驾驶任务中，左侧背外侧前额叶皮质的活动显著低于高道德组，而右侧背外侧前额叶皮质的活动在自我危险驾驶任务中低于安全驾驶任务。无论道德价值观如何，参与者在危险驾驶期间对道德情绪的敏感度较低。此外，我们的研究结果表明，道德价值观较低的驾驶员可能对道德情绪的敏感度更低。
