The role of eye movements in motion perception

  • Abstract

Informations and abstract

Keywords: Motion perception, motion coherence, eye movements, direction discrimination.

The literature has not yet clarified what the role of eye movements is in motion perception when it is not possible to track the moving stimulus. In this study we recorded the eye movements of forty participants during a «motion coherence» task that prevented tracking, to investigate if and how eye movements contributed to the accuracy in motion perception. The ability to discriminate the direction of movement was studied as a function of eye movements velocity measured by infrared video ocular system. The results confirm that the eye movements velocity predicts the accuracy in motion perception. This suggests that there is an initial process that unifies the systems that govern eye movements and motion perception
