Information Transmission during Eye Movements

Abstract

Target stimuli (the numeral 5 at 60 degrees to the left of the subject's fixation point) were extinguished at various times during the subject's eye movement to that stimulus and the subject was asked to guess what numeral had occurred. Threshold functions were constructed from these data, and it was found that at the beginning of the backward compensatory movement, very little information was transmitted. However, as the backward compensatory movement progressed, there was an increase in the correct identification of the stimulus, and a threshold was reached before the forward compensatory movement began. © 1979, Human Factors and Ergonomics Society.
