Early experience and serotonin transporter gene variation interact to influence primate CNS function
An environment-dependent effect of the rh5-HTTLPR genotype on CNS 5-HT function is demonstrated and nonhuman primates may provide an important avenue for investigating gene/environment interactions using candidate genes for physiological and behavioral traits.
Monoamine oxidase A gene promoter variation and rearing experience influences aggressive behavior in rhesus monkeys
The results suggest that the behavioral expression of allelic variation in MAOA activity is sensitive to social experiences early in development and that its functional outcome might depend on social context.
Early determinants of behaviour: evidence from primate studies.

The idea that early experiences disproportionately influence adult behaviour has long been a fixture of mainstream developmental theory, and early social relationships with mothers or other caregivers appear to provide especially powerful determinants of behavioural propensities throughout the lifespan.
Rearing condition and rh5-HTTLPR interact to influence limbic-hypothalamic-pituitary-adrenal axis response to stress in infant macaques
It is demonstrated that serotonin transporter gene variation affects LHPA axis activity and that the influence of rh5-HTTLPR on hormonal responses during stress is modulated by early experience.
Neonatal Imitation in Rhesus Macaques
The findings provide a quantitative description of neonatal imitation in a nonhuman primate species and suggest that these imitative capacities are not unique to the ape and human lineage and their evolutionary origins may be traced to affiliative gestures with communicative functions.
Hand preference for a bimanual task in tufted capuchins (Cebus apella) and rhesus macaques (Macaca mulatta).
The authors conclude that using the same procedure to compare hand preference across species represents a powerful research tool that can lead to a more complete understanding of the evolution and ontogenesis of primate handedness.
Rearing experiences and stress-induced plasma cortisol as early risk factors for excessive alcohol consumption in nonhuman primates.
Findings suggest that early rearing experiences, such as adult absence, and high plasma cortisol concentrations early in life after a social separation stressor, are useful psychobiological predictors of future high alcohol consumption among nonhuman primates.
Effects of Early Life Stress on [11C]DASB Positron Emission Tomography Imaging of Serotonin Transporters in Adolescent Peer- and Mother-Reared Rhesus Monkeys
Results agree with the hypothesis that early maternal deprivation affects the development of the serotonergic system and suggest that decreasedSerotonergic innervations in the critical brain regions may explain some of the behavioral and biochemical abnormalities in PR monkeys.
Serotonin transporter gene polymorphism, differential early rearing, and behavior in rhesus monkey neonates
The results demonstrate the contributions of rearing environment and genetic background, and their interaction, in a nonhuman primate model of behavioral development.
