年轻驾驶员是车辆碰撞的高风险群体，因为他们在检测即将发生的碰撞方面缺乏经验，并且是可以从感知学习（PL）培训中受益的一个群体。本研究评估PL是否可以用来提高碰撞检测的性能。10名大学年龄的受试者参加了第一个实验，其中包括7个1小时的会议在不同的日子进行。在三个观察者/对象的速度进行了测量，训练前使用两个替代的强制选择程序，在此过程中，他们表示是否接近的对象将导致碰撞或非碰撞事件。然后，参与者以这些速度之一在阈值附近训练5天。训练后，参与者在训练速度下检测碰撞所需的时间显着减少。这种改进也被发现转移到更高的观测速度条件。进行第二个实验，以确定这种改善是否是由于训练接近阈值或这种改善是否仅仅是由于与任务的实践。用远高于阈值的刺激进行训练，表现没有显著改善，这表明在第一个实验中看到的改善不仅仅是由于任务练习。
Young drivers are a high-risk group for vehicle crashes due to inexperience in detecting an impending collision and are one group that may benefit from perceptual learning (PL) training. The present study assessed whether PL could be used to improve performance in collision detection. Ten college-aged subjects participated in the first experiment, which consisted of seven 1-hr sessions conducted on separate days. Thresholds at three observer/object speeds were measured prior to training using a two-alternative forced choice procedure during which they indicated whether an approaching object would result in a collision or noncollision event. Participants were then trained near threshold at one of these speeds for 5 days. After training, participants showed a significant reduction in the time needed to detect a collision at the trained speed. This improvement was also found to transfer to the higher observer speed condition. A second experiment was conducted to determine whether this improvement was due to training near threshold or whether this improvement was merely due to practice with the task. Training with stimuli well above threshold showed no significant improvement in performance, indicating that the improvement seen in the first experiment was not solely due to task practice.
