title: Effects of tobacco, time on task, and stimulus speed on judgments of velocity and time.
abstract: 16 college students were required to predict the time of target arrival for a stimulus apparently moving horizontally to a point of occlusion and to reproduce the time interval the stimulus was present under smoking and no-smoking conditions. Tobacco resulted in underestimations of velocity and time judgments particularly in the early stage of the task and for the slowest stimulus speed.
