The basic assumption is that with a constant percentage of reinforcement, resistance to extinction (RE) would be a function of uncertainty associated with a reinforcement pattern. 3 groups of rats (double-alternation, 50% random, and continuous) were run in a runway. The last group extinguished most rapidly. No difference in RE was found between the other 2 groups. The conditional entropy of reinforcement-response sequences for the alternation group, as compared with the random group, failed to decrease when its orders were the 3rd or higher. These findings indicate that the <I>second-order</I> conditional entropy will be appropriate for quantifying the uncertainty in question. It was proposed that the RE as determined by uncertainty would be accounted for through intelligibility hypothesis, arousal hypothesis, or probability learning hypothesis.
