An integrated framework for the role of oxytocin in multistage social decision ‐making
Interest in the effects of oxytocin on social behavior has persisted even as an overarching theory describing these effects has remained largely elusive. Some of the earliest studies on the effects of oxytocin on social decision‐making indicated that oxytocin might enhance prosocial actions directed toward others. This led to development of the prosocial hypothesis, which stipulates that oxytocin specifically enhances prosocial choices. However, further work indicated that oxytocin administration could elicit antisocial behaviors as well in certain social situations, highlighting the importance of context‐dependent eff...

Hand preference on unimanual and bimanual tasks in Barbary macaques (Macaca sylvanus)
The presence of group‐level handedness in non‐human primates remains controversial, as different studies have produced inconsistent results. Bimanual coordinated tasks have been found to elicit more pronounced hand preferences than simple unimanual tasks. The aim of this study was to examine manual lateralization in a group of 15 Barbary macaques during unimanual and bimanual tasks. In the unimanual task, data on simple food reaching in a foraging context were collected. During the bimanual task, macaques had to use one hand to hold a tube‐shaped apparatus while reaching with the other hand to retrieve the food insid...

Intranasal oxytocin modulates neural functional connectivity during human social interaction
Oxytocin (OT) modulates social behavior in primates and many other vertebrate species. Studies in non‐primate animals have demonstrated that, in addition to influencing activity within individual brain areas, OT influences functional connectivity across networks of areas involved in social behavior. Previously, we used fMRI to image brain function in human subjects during a dyadic social interaction task following administration of either intranasal oxytocin (INOT) or placebo, and analyzed the data with a standard general linear model. Here, we conduct an extensive re‐analysis of these data to explore how OT modulates ...

Trauma rates and patterns in specific pathogen free (SPF) rhesus macaque (Macaca mulatta) groups
There are some predictable patterns of trauma in captive rhesus macaque (Macaca mulatta) social groups. Several factors have been documented to contribute to these patterns, including group formation of unrelated animals, and the establishment of dominance ranks. Here, we report on how socially induced trauma in groups of rhesus monkeys is influenced by the breeding season, numbers of matrilines per group and matriline size. We analyzed 3 years of data collected from veterinary admittance logs for four groups in our specific pathogen free (SPF) breeding colony. Since the groups differed in time from formation, both the num...

Parentage complexity in socially monogamous lemurs (Eulemur rubriventer): Integrating genetic and observational data
Genetic analyses of parentage sometimes reveal that “socially monogamous” (pair‐living) species do not reside in strict family groups. Circumstances such as adult turnovers and extra‐pair copulations, among others, may result in non‐nuclear families. These genetic relationships within groups have implications for interpreting social behaviors. Red‐bellied lemurs (Eulemur rubriventer) live in groups generally comprising an adult male‐female pair plus immatures, and early genetic analyses of parentage in a relatively small sample suggested they mate monogamously. However, previous research on this taxon has als...

The effect of extreme weather events on hair cortisol and body weight in a wild ring ‐tailed lemur population (Lemur catta) in southwestern Madagascar
We examined the effects of sequential weather periods, drought, normal, cyclone and post‐cyclone, on hair cortisol concentrations (HCC) and body weight in wild ring‐tailed lemurs, Lemur catta (n = 185), at the Bezà Mahafaly Special Reserve in southwestern Madagascar. Data were modeled and analyzed by sex, age, and troop. Given the ecological consequences of extreme climatic perturbations, we hypothesized that drought and cyclone would significantly impact lemur HCC. Among adults, drought was associated with higher HCC than other periods and the lowest HCC was associated with the post‐cyclone period. Adult female...
