SUMMARY Grooming behaviour was studied quantitatively by observing pairs of oppositely sexed, adult rhesus monkeys during regular hourly test sessions over 2 yr.; at all other times the animals were caged singly. Rhythmic fluctuations in both male and female grooming occurred in relation to the menstrual cycle; the grooming times of males reached a maximum near mid-cycle, at which time the females' grooming was at a minimum. In some pairs, there were additional changes in the grooming times immediately before menstruation in the same direction as those near mid-cycle. Bilateral ovariectomy of the female of the pair abolished all rhythmic variations and reduced the grooming of the males. Subcutaneous injections of oestradiol into the ovariectomized female restored the grooming of males to the levels seen near mid-cycle. The subsequent addition of progesterone partially, but always consistently, antagonized the effects of oestradiol. Analysis of the hormone-induced alterations in grooming behaviour indicates a primary influence on the effectiveness of the grooming invitations of females, the proportion accepted by males increasing with oestradiol administration. These findings indicate that endocrine factors play a role in regulating grooming activity which constitutes an important aspect of the social behaviour of primates.

AbstractThis study dealt with factors affecting agonistic communication in rhesus monkeys. Definitions were given for various postures, facial expressions, and vocalizations. The data revealed that such communications depended at least upon the following factors: 1. Age Dominance displays (yawning, threats) increased with age while fear grimaces and vocalizations decreased with age. 2. Sex Dominance displays occurred more often and fear grimaces and vocalizations less often in males than in females. Crook tail should be used with caution as a measure of dominance, at least in subadult rhesus monkeys. The average duration of crook tail seemed to be a more relevant index of dominance than the frequency of crook tail. 3. Rearing Motherless mothering and peer deprivation depressed displays of dominance, while rotated mothering increased dominance displays. Repeated separation produced submissive and dependent behavior; however, calls for social contact (coos) were emitted much more frequently in these animals. This vocalization change was probably a product of social learning. 4. Social stimulus Displays of dominance and submission were dependent upon the nature (i.e., size, age, hostility) of the social partner. 5. Adaptation to the social partner Dominance related behaviors decreased and calls for friendly contact increased as the animal became more familiar with a strange social partner.
