title: Brightness-discrimination learning in cats is influenced by early visual deprivation.
abstract: A two-choice apparatus for food reward was used. Normal and visually deprived cats were trained to discriminate white and black cards. After the animals had reached criterion, the contrast difference between the cards was diminished in steps. When the brightness ratio had been reduced to 1.8, discrimination was impaired in the deprived cats and not in the normally raised cats.
