In 2 experiments, 2 intertrial intervals (90sec or 24hr) and reinforcement schedules (continuous or partial) were combined factorially for 60 rats in straight alley type learning. One 320-mg pellet per reinforced trial was given in Exp. I, and sixteen 20-mg pellets in Exp. II. The rats received only 5 training and 20 extinction trials. A significant partial reinforcement effect (PRE) was obtained irrespectively of the length of intertrial interval or of the number of pellets. The data were not consistent with Amsel's hypothesis that the small-trial PRE was affected by the number of pellets given. Several implications of the present results were discussed in relation to Capaldi's stimulus-aftereffect hypothesis.
