The purpose of this laboratory study was to investigate the influence of time pressure on the perception of speed and duration in driving situations. Participants provided estimations of speed and performed both productions and reproductions of time durations, based on traffic films. The experimental films were made from a driver's point of view within a moving car, and audio-recorded instructions invited participants to imagine that they were driving while under time pressure or while relaxed. The results obtained using this within-participant design support the hypothesis that time pressure promotes fast driving, and may induce an underestimation of speed and trip-related durations, the latter of which suggests that time pressure modulates time perception. Some of these effects were mediated by the emotional impact of time pressure. Links between time perception and speed were also observed. The discussion makes reference to internal clock models and focuses on the practical consequences of these results.
本实验室研究旨在探究时间压力对驾驶情境中速度和时长感知的影响。参与者根据交通影片提供速度估计，并进行时长的生成和再现任务。实验影片从车内驾驶员视角拍摄，并通过音频记录指令，邀请参与者在有时间压力或放松状态下想象自己在驾驶。本采用被试内设计的研究结果支持了以下假设：时间压力会促使驾驶速度加快，并可能导致对速度和行程相关时长的低估，后者表明时间压力会调节时间感知。其中一些影响受到时间压力情绪影响的调节。还观察到时间感知与速度之间的联系。讨论参考了内部时钟模型，并重点关注了这些结果的实际影响。
