Prediction of preschool social behavior from social-emotional development at one year

In an attempt to directly investigate later consequences of the early mother-infant relationship, several measures of social-emotional and cognitive-motivational development at 12 months of age were correlated with two measures of preschool adjustment for 26 children. Results indicated that both of our measures of early social functioning were related to more optimal adjustment in a peer-setting at three-and-a-half years of age. Taken together, the results of the study provide empirical support for the widely held, but seldom tested, hypothesis that the quality of the early mother-infant tie has important consequences for the child's subsequent development in most areas.
