Abstract: | The performance of 22 adult male rhesus monkeys on a Fixed Interval 1-min reinforcement schedule was examined under conditions
where the reinforcement probabilities were either 1.00 or .80. The results were then related to the social rank of animals
at the time that they were taken from their social groups. Both high and low ranked animals reached criterion performance
in the same number of trials. In general, high ranking animals responded at lower rates than low ranking animals when the
reinforcement probability was 1.00. When the reinforcement probability was shifted to .80, all animals showed an increase
in responding after nonreinforced intervals as compared with responses after reinforced intervals. The higher ranked animals
tended to have a higher ratio of nonreinforced to reinforced responses than lower ranked animals.
