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感知的影响。【a】我们测量了参与者自由执行复杂动态视觉任务时的有效视野。【b】我们研究了被试在观看描述日常情景的动态视觉电影时的时间感知扭曲，发现知觉表达引起了时间扭曲。【c】我们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性能的变化。此外，我们还进行了初步实验，研究了多目标跟踪过程中听觉刺激和注意力分散对视觉感知的干扰，这使得将本研究结果扩展到更现实的条件（如3D空间）成为可能。

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.
