Attention Perception & Psychophysics

Usually people can estimate the correct position of a moving object even when it temporarily moves behind an occlusion. Studies have been performed on this type of occluded motion with prediction motion (PM) tasks in the laboratory. Previous publications have emphasized that people could use mental imagery or apply an oculomotor system to estimate the arrival of a moving stimulus at the target place. Nevertheless, these two ways cannot account for the performance difference under a different set of conditions. Our study tested the role of time structure in a time-to-collision (TTC) task using visual and auditory modalities. In the visual condition, the moving red bar travelled from left to right and was invisible during the entire course but flashed at the initial and the occluded points. The auditory condition and visual condition were alike, except that the flashes in the visual condition were changed to clicks at the initial and the occluded points. The results illustrated that participants' performance was better in the equal time structure condition. The comparison between the two sense modalities demonstrated a similar tendency, which suggested there could be common cognitive processes between visual and auditory modalities when participants took advantage of temporal cues to judge TTC.
