Abstract
Two groups of rats received 112 large- or small-reward training trials, respectively, in a straight runway. Trials were administered at the rate of four per day. A comparison of within-day trial-by-trial analyses, performed over the last 6 days of training, indicated that the occurrence (or lack) of reward magnitude effects was a function of which daily trials were analyzed.
