Driver distraction due to cellular phone usage has repeatedly been shown to increase the risk of vehicular accidents; however, the literature regarding the use of other personal electronic devices while driving is relatively sparse. It was hypothesized that the usage of an mp3 player would result in an increase in not only driving error while operating a driving simulator, but driver anxiety scores as well. It was also hypothesized that anxiety scores would be positively related to driving errors when using an mp3 player. 32 participants drove through a set course in a driving simulator twice, once with and once without an iPod mp3 player, with the order counterbalanced. Number of driving errors per course, such as leaving the road, impacts with stationary objects, loss of vehicular control, etc., and anxiety were significantly higher when an iPod was in use. Anxiety scores were unrelated to number of driving errors.
因使用手机导致的驾驶员注意力分散已多次被证明会增加车辆事故风险；然而，关于驾驶时使用其他个人电子设备的文献相对较少。研究假设，使用MP3播放器不仅会导致在驾驶模拟器操作过程中驾驶失误增加，还会使驾驶员焦虑得分升高。研究还假设，使用MP3播放器时，焦虑得分与驾驶失误呈正相关。32名参与者在驾驶模拟器中沿着固定路线行驶两次，一次使用iPod MP3播放器，一次不使用，顺序平衡。使用iPod时，每条路线的驾驶失误数量，如驶离道路、与静止物体碰撞、失去车辆控制等，以及焦虑程度都显著更高。焦虑得分与驾驶失误数量无关。
