Early proximo-distal development in the mother's contact behavior during nursing

Maternal social and physical contact: links to early infant attachment behaviors

The relationship between maternal physical and social contact styles and infant attachment behavior under stress and nonstress conditions was studied at 2 different age points during the 1st year of life. The infants (29 girls and 15 boys) and their mothers were observed in their homes at 4 and 7 months of age. Maternal physical and social contact behaviors during an unstructured observation were rated on the Clarke-Stewart Rating Scales. Infant attachment behaviors in semistructured interactions with their mothers and with a stranger were rated on the Attachment Indicators Rating Scale. Scores on all attachment behaviors were subjected to a principal-axes factor analysis with varimax rotation, and one-way analyses of variance were conducted to assess effects of maternal social and physical contact at 4 and 7 months. A significant link was found between maternal physical contact at 4 months and the infant's attachment behavior under conditions of stress and play at both 4 and 7 months. Maternal social contact at 4 months was linked to attachment behavior in play situations, but not in stress situations. By the age of 7 months, the infants' attachment behavior under both stress and play conditions was linked to concurrent social and physical maternal contact. Maternal physical and social contacts at 4 and 7 months were linked to concurrent infant proximal attachment behavior, but such contacts at 4 months were not predictive of later infant proximal behaviors. These findings suggest that the relationship between the intensity and style of maternal contact and infant attachment behavior varies with age.
