Abstract

Three male cats were trained to depress a foot pedal as a conditioned response to the presence of an illuminated target. The animals were then exposed to a flash with a visual angle of 20° and peak luminance of 5.0×106 lm. The total energy at the corneal surface was 0.26 J/cm2. The visually dependent conditioned responses to each of five target conditions (4.15, 0.359, 0.029, and 0.0029 mL for the dark-adapted cat eyes and 4.15 mL for the light-adapted eyes) were then taken as their recovery times. The results showed that when the energy of the adapting flash remained constant, a decrease of the luminance of the target resulted in an increase of the recovery times of the cat.
