Mothers' characteristics, interactions, and infants' characteristics.
Stable characteristics of rhesus monkey mothers, in terms of Confident and Excitable scores, were significantly positively correlated with the respective scores of their daughters but not their sons. With sons, mothers' Excitable scores were significantly negatively correlated with sons' Confident scores. Correlations of the maternal scores with earlier mother/infant interactions suggest how mothers' characteristics could have influenced infant characteristics. Mothers' Confident scores were negatively correlated with both rejecting and leaving their daughters. When a year old the daughters, on the other hand, left mothers relatively frequently and played a relatively low role in maintaining proximity. For both sons and daughters, mothers' Excitable scores were positively correlated with approaching and leaving their infants, as well as restricting at the age of weaning. Infants approached Excitable mothers relatively frequently, and year-old sons played a relatively high role in maintaining proximity with mother. In terms of attachment theory, Confident mothers appear to provide a "secure base" for their daughters, but reject their sons when very young. Excitable mothers appear to behave inappropriately to both sons and daughters, producing infants who may be "insecurely attached."
