Thesis (Ph.D.)--New York University, 1995.

The present study examines the relationship between social environment and somatic growth and skeletal development in 40 female rhesus monkeys (Macaca mulatta) housed outdoors in group cages. Among primates, social networks provide support, which is thought either to buffer the recipient from the effects of stress (the "stress-buffering" theory) or provide health benefits directly, regardless of levels of stress (the "main-effect" theory). Prior research has suggested that the buffering or direct benefits of social support may accelerate sexual maturity and other developmental processes, and enhance reproductive fitness. An alternative model (the "early-stress" model) proposes that stress experienced early in life contributes to accelerated sexual maturity. The present research tests the predictions of those models and provides new information concerning the role of social environment in shaping life-history processes.Subjects--Topical Terms:

520 $a The present study examines the relationship between social environment and somatic growth and skeletal development in 40 female rhesus monkeys (Macaca mulatta) housed outdoors in group cages. Among primates, social networks provide support, which is thought either to buffer the recipient from the effects of stress (the "stress-buffering" theory) or provide health benefits directly, regardless of levels of stress (the "main-effect" theory). Prior research has suggested that the buffering or direct benefits of social support may accelerate sexual maturity and other developmental processes, and enhance reproductive fitness. An alternative model (the "early-stress" model) proposes that stress experienced early in life contributes to accelerated sexual maturity. The present research tests the predictions of those models and provides new information concerning the role of social environment in shaping life-history processes.
520 $a Morphometric and radiographic data collected over a three-year period were used to assess growth and skeletal maturation. Assays for cortisol, growth hormone, and somatomedin-C were conducted to evaluate hormonal mechanisms mediating the effects of social environment on growth and development. Behavioral data were used to define social environment. Individual focal--or other--animal behaviors, as well as factors reflecting relationships among groups of behaviors, were correlated with plasma cortisol levels, morphometric measurements, and skeletal maturation indices. From those analyses, behavioral measures of stress and social support were identified. Variation in growth and development associated with dominance rank was also explored using repeated measures analyses of variance. Interactions between social support and stress were evaluated using regression analyses of bone maturation indices on dominance rank and a factor reflecting overall level of social contact. Results support the predictions from the stress-buffering model and provide no evidence for the early-stress model.
520 $a Behavioral factors reflecting dominance and affiliation emerged from observations of focal/other animal interactions, suggesting that the corresponding dimensions already found to underlie human behavior have their roots in primate behavior. Those findings are discussed relative to human interpersonal theory and models concerning the evolution of primate behavior. It is concluded that the stress response is beneficial insofar as it constrains the range of acceptable species-specific behaviors and prevents social disintegration, with subsequent reproductive consequences.
