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)

To assess the effects of the onset of mothers' inaccessibility to their infants, infant-mother pairs were observed in the Ainsworth strange situation at both 12 and 18 months and were classified as secure, anxious-avoidant, or anxious-resistant. Children of mothers who had returned to work/school before their child was 12-months-old were more…

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)

Examines 2,000 Strange Situation classifications obtained in eight different countries. Differences and similarities between distributions in classifications of samples are investigated using correspondence analysis. Substantial intracultural differences are established; data also suggest a pattern of cross-cultural differences. (Author/RWB)

Findings indicated that attachment-related affect may reflect an affect continuum that underlies certain mother- and stranger-directed behaviors in the Strange Situation. However, not all aspects of reunion behavior can be predicted by prior separation reactions. (Author/RH)

In a study of attachment behavior 10-month-old infants were observed under three conditions: with the mother, with an adult female stranger, and when both were present. Infants directed more social responses to the mother, but the stranger evoked more exploration behavior than distress. (ST)

Forty-three infants and mothers were observed in the Strange Situation when infants were 12.5 and 19.5 months old. Following each assessment, mothers completed a questionnaire concerning changes in family and care-giving circumstances. Results indicate that security of attachment reflects the current status of infant-mother interaction and that…

Sixteen children at each of ages two, three, and four years were observed being approached by and interacting with a friendly stranger during their mothers' presence and absence. While analyses of discrete behaviors yielded results consistent with those of earlier studies, analyses based on a behavioral systems approach identified age and…

A model of infant social behavior is developed which incorporates attachment to the familiar and fear of strangers as well as detachment from the familiar and exploration of the stranger. (JMB)

To assess the validity of attachment scores derived from the Ainsworth "strange situation", 56 1-year-olds and 79 2-year-olds accompaned by either the mother, the father, or a brief acquaintance were studied. Proximity to the adult, duration of play, crying, activity, and the incidence of looks and distance bids were measured. (Author/CS)

Social behaviors of 10- and 12-month-old infants were studied as a function of experimental context (home and laboratory) and experimental history (home rearing and day care). Results suggested that the experimental context influenced infant social behaviors. No differences attributable to rearing condition as a main effect were found. (Author/SB)

Children classified as securely attached at 12 months interacted faster and more smoothly with the stranger than did avoidantly-attached peers. Microanalyses revealed different styles of interaction. Failure feedback increased efforts of securely-attached and decreased efforts of insecurely-attached children. After failure, securely-attached…
