ABSTRACT
This chapter presents the author's account of pursuit system's contribution in converting temporal to spatial visual information. It provides a new twist to the classic anorthoscopic effect or visual persistence where successive portions of a display contribute to the painting on the retina of the entire visual image. The chapter then describes experiments with an intriguing design in an attempt to resolve the issue of smooth pursuit's contribution to space perception using intermittent right-to-left and left-to-right going stimuli to paint the retina. The aim of the first experiment was to see if observers could in fact make pursuit eye movements to follow a target moving backwards and forwards behind a slit. The target in this experiment was an outline circle 1.8° in diameter moving behind a slit that varied in width between 0.1 and 3.6°. The circle oscillated in linear motion between left and right with a peak-to-peak amplitude of 3.6°.
