Research Abstract

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.
