Extinction as a Function of a Small Number of Partially Reinforced Trials

Abstract
After preliminary exploration [of a straight-alley maze] 23 naive rats were divided into 2 groups. One group received a reinforced, a nonreinforced, then another reinforced trial. The second group received 3 reinforced trials. During extinction the partial reinforcement group ran faster. This was discussed in relation to Spence''s and Amsel''s analyses of partial reinforcement.".
