Changes of brightness sensation (fading) that occur when images are stabilized on the retina were measured with a matching technique. Increment thresholds were measured under the same conditions. Under stabilization, the increment threshold is proportional to stimulus level (Weber’s law). Increment thresholds change at a different rate than does brightness; this suggests that these mechanisms behave independently.
