Eye Movements and Spatial Pattern Vision.
Abstract
Spatial patterns became substantially less visible when held stationary (stabilized) on the retina. Calculations showed that residual visibility of stabilized high contrast patterns can be attributed to slight failure of stabilization. Stabilization showed further that eye movements play an important role in detection of drifting and flickering grating patterns. The substantial differences in sensitivity to low-contrast grating patterns of various spatial and temporal frequencies were not observed when apparent contrasts of high-contrast gratings were determined. Approximately equal physical contrasts produced equal apparent contrasts. (Author)
