Abstract

Dogs were raised from infancy to maturity in lighted cages that restricted their visual experience but did not deprive them of all patterned stimulation. After they were released from their cages, they had greater difficulty than normally reared littermates in performing a simple black-white discrimination and in subsequent reversal training.
