This study tested the hypothesis that one year old infants' wary behavior toward an unfamiliar female adult would decrease and affiliative behavior would significantly increase in the course of a relatively brief period. (Author/SB)

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)

Supports the hypothesis that temperamentally fussier 5- to 9-month-old infants are more fearful and less friendly toward strangers than are more easygoing infants of the same age. (MP)

Hypothesizes that infants with attentive mothers will interact more positively with consistent partners than with matched strangers. Finds that when mothers were attentive infant dyads composed of consistent partners interacted more than stranger dyads. Suggest that withdrawal of maternal attention may be equivalent to physical separation by a…

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)

Two experiments investigated 8-, 10-, and 12-month-old infants' levels of searching for mothers, strangers, and objects. Found that, overall, 10- and 12-month-old infants had higher levels of searching for mothers, whereas youngest infants showed no differences for searching. This discrepancy is likely due to social cognitive development and…

A group of 3-year-old children were observed in a Strange Situation immediately prior to admission to day care and again three months later. Their behavior was compared with that of a control group, matched in all respects except for the fact that their parents had no plans to enroll them in day care. (SB)

Demonstrates that eye contact per se, and not solely the inherent attractiveness of the eyes and face, is salient to five-month-old infants. Five-month-old infants can distinguish when another person is looking at them, rather than at a nearby location. (Author/MP)

Aim of this study was to obtain direct observations of attachment and exploration behaviors exhibited in a strange situation by children with Down's syndrome and a control group of normal children. (JH)

Describes characteristics of the attachment behavior of 10 infants blind from birth. Behaviors studied were smiling, discriminating tactile behaviors, stranger avoidance and distress, and separation and reunion behaviors. (BRT)

Assessed infants' attachment behaviors toward nonparental adults, including grandparents, other relatives, and family friends. Found that the extent of infants' attachment behavior to nonparental adults was related to infant-mother attachment behavior and to the nonparental adult's responsiveness in teaching and position in the mother's social…

Examined effects of the age of adult female strangers on the affective behavior of 60 Japanese toddlers. The first study investigated the importance of the age discrepancy between mothers and female strangers aged 23 and over 65. The second study compared toddlers' reactions to mothers, men and women strangers the mother's age, and men and women…

Examined cortisol and behavioral reactions of 36-month olds in an unfamiliar playgroup. Found that, when compared to at-home levels, cortisol levels were lower when children were receiving adult support and higher for one-third of children when interacting with peers alone, and that children showing adrenocortical arousal before the challenging…

Examined middle and lower class Anglo-American and Puerto Rican mothers' sociocultural values and perceptions of attachment behavior. Anglo mothers focused on self-confidence, independence, and autonomy, whereas Puerto Rican mothers focused on obedience, relatedness, and demeanor. Findings indicate the need for culturally sensitive models of the…
