Distortion of Space and Time during Saccadic Eye Movements
ABSTRACT
The space-time distortion perceived subjectively during saccadic eye movements is an associative phenomenon of a transient shift of observer’s visual frame of reference from one position to another. Here we report that the lines of subjective simultaneity defined as two spatially separated flashes perceived during saccades were nearly uniformly tilted along the physical time-course. The causality of the resulting space-time compression may be explained by the Minkowski space-time diagram in physics.
