The majority of vehicle accidents are attributable to driver error, such as substance use, distractions, fatigue, speeding, and driving experience. Many of these driver errors are also associated with delay discounting, where individuals that excessively devalue a reward are more likely to use substances such as alcohol, cigarettes, and cocaine, and text-while-driving. The current study sought to examine a more direct association between delay discounting and driver error by providing 50 participants with a series of simulated driving tasks, along with measuring their delay discounting rates. A median-split for delay discounting rates showed that participants with high-delay discounting rates made significantly more total errors for simple driving tasks (e.g., braking and one-lane change) early during the simulation, relative to participants with low-delay discounting rates. On the other hand, high-delay discounting participants continued to make more total errors for a more complicated two-lane change driving task after multiple trials, relative to low-delay discounting participants. These results support the idea that delay discounting is a transdisease process that can significantly negatively affect a large range of health-related behaviors, including driver errors. Treatment implications for reducing driver errors are discussed.

模拟驾驶任务中驾驶员错误和延误折扣之间的关系

大多数车辆事故均归因于驾驶员的失误，例如物质使用，注意力分散，疲劳，超速和驾驶经验。这些驾驶员错误中的许多错误也与延误折扣相关，在延误折扣中，过度贬低奖励的个人更有可能使用酒精，香烟和可卡因等物质，并在开车时使用文字。当前的研究试图通过为50名参与者提供一系列模拟驾驶任务，并测量他们的延误折扣率，来检验延误折扣与驾驶员错误之间的更直接关联。延迟贴现率的中位数拆分显示，在模拟初期，具有高延迟贴现率的参与者在简单驾驶任务（例如，制动和单车道变更）上的总错误明显增加，相对于低延迟折扣率的参与者。另一方面，相对于低延迟打折参与者，高延迟打折参与者在多次试验后对于更复杂的两车道变更驾驶任务仍会犯更多的总错误。这些结果支持这样的观点，即延迟贴现是一种疾病转变过程，可能对包括驾驶员错误在内的各种健康相关行为产生重大负面影响。讨论了减少驱动程序错误的处理方法。这些结果支持这样的观点，即延迟贴现是一种疾病转变过程，可能对包括驾驶员错误在内的各种健康相关行为产生重大负面影响。讨论了减少驱动程序错误的处理方法。这些结果支持这样的观点，即延迟贴现是一种疾病转变过程，可能对包括驾驶员错误在内的各种健康相关行为产生重大负面影响。讨论了减少驱动程序错误的处理方法。
