     Assessment of social interactions is the foundation of compatibility evaluation for newly paired laboratory monkeys. Identification of behaviors key to decision-making in introductions is essential for maximizing personnel efficiency and for pair management. Data from 24 successful introductions of isosexual rhesus macaque pairs (6 male, 16 female; 2-25 yrs old) were examined. The presence or absence of social behaviors was noted during three phases of the introduction: visual, limited contact, and paired contact. Progression through the phases was dependent upon behaviors observed. More pairs displayed grooming (p = .001) and other non-aggressive contact behaviors (p=.006) in the paired phase (79%, 84%) than in the limited contact phase (33%, 42%) as measured by a related-samples McNemar Test. Aggressive contact did not differ between phases. The number of pairs displaying each non-contact behavior across all three introduction phases was compared using a related-samples Cochran’s Q test. Increasing numbers of pairs displayed social enlisting (p < .001) as the introduction phases progressed. The number of pairs displaying avoidance or withdrawing behavior changed across phases (p = .001); the highest proportion was observed in the limited contact phase. There was no observed change in the number of pairs displaying lip-smacking, presenting, or lunging across the introduction phases. Results will be useful in understanding common patterns of behavioral change in successful rhesus pairs; these can better inform socialization program decisions.
