Peripheral field stimulation affects foveal flicker, but not color, sensitivity.
Human observers have different thresholds for flicker detection and color detection of a rapidly flickering spectral stimulus presented on a steady white background. A flickering surround, which did not overlap the stimulus or background, reduced flicker sensitivity but not color sensitivity for both monocular and binocular viewing. However, a flickering surround presented to one eye had no influence upon either color or flicker thresholds of the other eye.
