Abstract
Experiments in hearing showed that a time difference of 0.1 msec between the stimulation of the left and right ear by a similar click was enough to be recognized as a spatial shift of the integrated sound perception. Similar phenomena were obtained for taste stimulation on both sides of the tongue or with an odorous substance introduced to both nostrils. No similar phenomenon was obtained in binocular vision, when a short time difference between the stimulation of both eyes was introduced and the location of the fused image was observed. It was found that this peculiarity for vision could be eliminated when the stimuli for vision were made more identical to the stimuli used for the other sense organs, practically most of which were sweeping stimuli. Sweeping light stimuli with time differences of 0.1 msec between both eyes could be detected as spatial shifts with the same precision as for the other senses. This widens the expected similarities between the different sense organs.
