Document Summary

1- look at the fixation point in the right part of the screen. 2- place your finger on the start mark & move it slowly to the end mark while looking at the fixation. 3- do the same thing, but this time follow your finger w/ your eyes = smooth pursuit. *displacement on retina = same in both cases items moved across our retinas to right: perceive finger in motion when focus on fixation point, perceive fixation point to be stationary when focus on finger. But not perceived fixation point crossing fovea from right of finger to left of finger. Because eye movement = so brain compensated so not see fixation point move smooth pursuit. Voluntary eye movement eyes move smoothly to follow a moving object. Both voluntarily or involuntarily eye movement eyes rapidly change fixation from 1. Ex: eye moving all over the place when looking at face but not aware.
