Strayer, F. F. (1976). Learning and imitation as a function of social status in macaque monkeys (Macaca nemestrina). Anim. Behav., 24(4), 835–848.
Abstract: Learning and imitation were examined in animals selected from two groups of sixteen pigtail monkeys. There were significant differences in performance on a cued-alternation task as a function of both social status within the stable group, and prior exposure to a social model. High status animals responded more frequently, but were less successful in acquiring appropriate response delay. Exposure to the model improved response latencies and acquisition of response delay for all subjects. However, model exposure did not improve alternation performance. Results are discussed in terms of prior social experience of the subjects, general learning strategies, and differential sensitivity to multiple reinforcement contingencies. Findings are related to ethological concepts of imitation, and field reports on primate social learning.

Abstract: Recent studies of primates have questioned the importance of dominance hierarchies in groups living under natural conditions. In a herd of Highland ponies and one of Highland cattle grazing under free-range conditions on the Isle of Rhum (Inner Hebrides) well defined hierarchies were present. The provision of food produced a marked increase in the frequency of agonistic interactions but had no effect on the rank systems of the two herds. While rank was clearly important in affecting the distribution of agonistic interactions, it was poorly related to behaviour in non-agonistic situations.
