Learn what prominent theorists say about bonding, attachment, separation and stranger anxiety, and the best practices for infant care. This introductory guide makes it easy to learn about John Bowlby, Mary Ainsworth, Magda Gerber, John Kennell, Marshall Klaus, and T. Berry Brazelton.

Relations between infant-mother attachment security at 15 months and infants' (N = 206) joint attention behaviors (a) with an experimenter at 8 and 15 months, and (b) with their mothers at 15 months were investigated. No concurrent or longitudinal relations were observed between attachment security and infants' tendency to respond to an…

This study shows that 12-month-old infants direct more distal/affiliative behaviors to their fathers and show no preference between parents in proximal/attachment behaviors. However, with a stranger present, more proximal/attachment behaviors are directed toward the mother with no preference shown in distal/affiliative behaviors. (JMB)

In a longitudinal study of 29 middle-class Japanese infants, an attempt was made to identify early temperamental dispositions that predict later attachment classification. Specifically, Ainsworth Strange Situation observations at 12 months of age were preceded by, among others, observation of distress evident in newborns when a nipple was removed;…

Familiarity of the setting, the mother's presence, sex of the stranger, and the distance separating the infant and the stranger were varied to examine the expression of stranger fear in 32 infants from 6 to 11 months of age. (Author/JMB)

Results suggest that various aspects of Strange Situation behavior are related to both maternal and infant temperament, and that maternal temperament is a predictor of attachment security, particularly for Type A mother-avoidant infants. (Author/RH)

Under equivalent task conditions, assessed object and person concept attainment in securely and insecurely attached infants. Subjects were 16 male and 23 female infants from middle class families. (Author/RH)

This experiment tested the theoretical predictions concerning the patterns of visual fixation to representations of familiar and unfamiliar persons during the second quarter of the first year of life. Subjects were twelve 4-month-old and twelve 6-month-old infants. (Author/SB)

Investigates the possible relationships among the variables of infant's temperament, mother's mode of interaction, and the quality of the subsequent mother-infant attachment. (Author/NH)

Twenty infants were observed at home interacting with their mothers, fathers, and an unfamiliar investigator when they were 15, 18, 21, and 24 months of age. (Author/JMB)

Face-to-face interaction between 26 infants and their mothers and a relatively unfamiliar figure was observed longitudinally in the home environment when the infants were between 6 and 15 weeks of age. Normative findings indicated that infants became more responsive over this time period, whereas maternal behavior did not change. (Author/JMB)
