Total number of sessions is the total number of sessions rats required to reach the reward criterion. Total trials completed is the total number of trials rats completed under each schedule. Session duration is the average number of hours rats needed to reach the performance criterion. Values presented are mean ± SEM. N/A, Not applicable.
