Brightness vs. duration curves were measured for targets of constant luminance flashed against various steady background luminances. Increasingly intense backgrounds shifted the curves downward, and systematically reduced the amount of brightness enhancement. This suggests that brightness enhancement is determined by target brightness and cannot be due to refractoriness in spatially independent neural channels.
