Abstract

We investigated the maternal care patterns of rhesus macaque mothers who physically abuse their infants, and compared their infants' behavior to that of nonabused infants. Parametric and multidimensional scaling analyses indicated that abusive mothers have a distinct parenting style characterized by high rates of rejection and contact-breaking from their infants. Compared to control infants, abused infants exhibited signs of delayed independence from their mothers including higher rates of distress calls and anxiety, lower rates of contact-breaking, and differences in play. Several aspects of the abused infants' behavior were correlated with rates of abuse received during the first month, or with other maternal behaviors. These findings provide a more comprehensive characterization of the parenting styles of abusive mothers and the early behavioral development of their infants than previously available. Detailed knowledge of the early experience of abused infants is crucial for understanding possible pathological alterations in behavior and neuroendocrine function later in life. © 2006 Wiley Periodicals, Inc.
