Rats in Experiments 1 and 2 were run in a shuttle runway using a successive acquisition and extinction paradigm with short delays between trials. In Experiment 1 4 groups of rats experienced 100%, 87.5%, 62.5%, or 37.5% reinforcement. Daily acquisition sessions were followed by extinction sessions. <I>S</I>s in Experiment 2 experienced N-lengths of 0 (100% reinforcement), 1, 2, or 1, 2, and 3 during successive acquisitions. <I>S</I>s with N-lengths of 0 and discriminative N-R vs. N-N transition times did not produce increasing resistance to extinction across extinctions in either experiment. Partial reinforcement factors other than N-length during acquisition determined successive extinction performance.
