Two experiments examined operant leg kick responses to a panel by six 3-month-old infants under baseline, immediate reinforcement, delayed reinforcement, and yoked-control conditions using a discrete trial procedure and a single-subject repeated-measures design. Two infants participated in the first experiment and four infants participated in the second experiment. The research design of Experiment I was baseline (A), 5s delay of reinforcement (C), yoked-control (A'), and immediate reinforcement (B). There were two experimental orders in the second experiment. The first order consisted of baseline (A), immediate reinforcement (B), yoked-control (A'), and 5s delay of reinforcement (C). The second order consisted of baseline (A), 5s delayed reinforcement (C), yoked-control (A'), and immediate reinforcement (B). The reinforcer was a combination of multicolored holiday lights and music, and a moving hand puppet. Changes in experimental phases were based on the attainment of learning and stability criteria. With the exception of one infant, leg kicks to a to a panel were learned under both immediate and 5s delay of reinforcement conditions, with learning appearing to be attained more rapidly under immediate reinforcement.
