Abstract
Laboratory rats were trained on either a discrete-trial or a free-responding program of bar presentation, with number of barpresses controlled. Half of the Ss received 16% sucrose in water as reinforcement, half 64%. The most important result was that Ss which had the discrete-trial type of training produced reliably more responses in extinction, regardless of the extinction program.
