The Role of the Pupil, Corneal Reflex, and Iris in Determining the Perceived Direction of Gaze

Stuart Anstis. Iperception. .

Abstract

In specially constructed movies depicting moving eyes, the pupils, irises, and corneal reflexes moved independently and sometimes in opposite directions. We found that the moving pupils or the corneal reflex, not the moving irises, determined the perceived direction of gaze (online Movie 1). When the pupils and irises moved in opposite directions, the one with the higher Michelson contrast determined the perceived direction of gaze (online Movie 2).

Keywords: eye movements; gaze; induced movement; iris; local motion; pupil.
