Effect of pre-adapting spectral stimuli on visual responses

Electroretinograms (ERGs) were recorded following pre-adapting exposures to radiometrically and photometrically matched spectral stimuli. The magnitudes of three aspects of the ERG varied as a function of the pre-adapting wavelength. Longer wavelenght pre-adapting stimuli produced less suppression of the response magnitudes than stimuli from the short wavelenght end of the spectrum. The implications of the findings for display design and cockpit-light-source design and management are discussed.
