An unfamiliar or strange situation was used as a setting to highlight individual differences in an infant's responses to brief separations from his mother and his reactions to a stranger. Two groups were observed, one composed of 23 white, middle class mother-infant pairs, the other of 33 pairs. Eight episodes, presented in fixed order for all…

Individual differences in four separation-related behaviors, protest, following, and positive greetings or crying on reunion, were examined for 26 infants observed intensively at home during the fourth quarter-year, and considered in relation to one another, to other infant behaviors, and to maternal behavior. Contrary to Freudian and other…

This paper has two major purposes: first, to consider how infant feeding behavior may fit into attachment theory; and second, to cite some evidence to show how an infant's early interaction with his mother in the feeding situation is related to subsequent development. It was found that sucking and rooting are precursor attachment behaviors that…

Findings are discussed in an evolutionary context, and with reference to the popular belief that to respond to his cries spoils'' a baby. (Authors)

An earlier version of this paper was presented at the annual meeting of the American Psychological Association at San Francisco, September 1968, in a symposium, "Attachment Behavior in Humans and Animals." (DR)

This report is based on a longitudinal analysis of physical-contact interaction of mother-infant pairs throughout the first year of life. The sample consisted of 26 middle-class mother-infant pairs who were observed in their homes for four hours once every three weeks. During each visit, the observer made a running record of everything that…

Reviews recent research advances in the areas of individual differences in the way maternal-infant attachment behavior becomes organized, differential experiences associated with various attachment patterns, and the values of such patterns in forecasting subsequent development. (Author/GC)

This report is a portion of a study of attachment behavior: behavior promoting contact and/or proximity of an infant to his mother figure. This report deals specifically with crying, response to brief everyday separations from the mother and to her return, and behavior relevant to physical contact with her. The subjects, 26 infant-mother pairs…

Several sets of evidence are offered to support the hypothesis that cognitive and social development are intimately interrelated, and that mother-infant interaction influences both. A mother's prompt responsiveness to her baby's signals tends to foster the development of varied and clear modes of communication and thus the development of one facet…
