High-amplitude sucking was studied as a conditioned operant response reinforced by visual feedback in 4-and 12-month infants. Typicalresponse acquisition and extinction effects were obtained. With the 12-month infants the conditioned sucking rates were influenced by amounts of redundancy in the visual reinforcers.
