Psychophysical study on perceptual space distortion by dynamic stimuli

本研究探讨了动态刺激对空间和时间知觉的影响。[a]We当参与者自由执行复杂的动态视觉任务时，测量有效视野。[b]We研究了被试在观看描述日常生活场景的动态视觉电影时的时间知觉失真，发现知觉表达导致了时间知觉失真。[c]We研究了瞬时事件的不可预测性对记忆的影响，发现时间的不可预测性而不是空间的不可预测性引起了记忆成绩的变化。此外，我们进行了初步的实验，以检查干扰的视觉感知由于听觉刺激和注意力的传播过程中的多个对象跟踪，这导致了目前的研究结果扩展到更现实的条件，如3D空间的可能性。

The present study investigated the effect of dynamic stimuli on the perception of space and time. 【a】We measured the effective visual field while participants were freely performing complex dynamic visual tasks. 【b】We examined the distortion of temporal perception while participants observing dynamic visual movies depicting everyday situations and found that the perceptual articulations causes the temporal distortion. 【c】We examined the effect of unpredictability of transient events on memory and found that the temporal unpredictability, rather than spatial unpredictability induced the change in memory performance. In addition, we conducted preliminary experiments to examine the disturbance of visual perception due do auditory stimulation and attentional spread during multiple object tracking, which led to the possibility of extending the present findings to more realistic conditions such as 3D space.
