Monocular or binocular and dominant or non-dominant eye observations can modulate vection strength respectively

Abstract

We examined whether vection strength could be modulated by the difference in the conditions of observing eyes, i.e. monocular or binocular observations and also, dominant eye or non-dominant eye observations. The eyepatch was used for making the monocular observation. The dominant eye was determined using the Miles Method. Eleven naïve volunteers and the second author participated in this experiment. Three vection measures (latency, duration and magnitude) were obtained. Obtained vection latency was significantly longer in the non-dominant-eye observing condition, although there were no significant differences in vection duration and magnitude. We can conclude that vection can be affected by the conditions of observing eyes.
