This study examined both differential patterns and the stability of infants' (N = 70) distress reactivity across mother and stranger arm-restraint conditions when infants were 6 and 9 months of age. Reactivity measures included observational variables for the rise, intensity, and duration of infant distress as well as motor activities associated…

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…

The reactions of 24 eight-month-old infants and their mothers were observed when approached in a standard laboratory situation by female strangers whose approach was either fast or slow. Mothers were significantly more "wary" than infants, particularly as the proximity of the stranger increased. (Author/RH)

Examined whether an infant's reaction to a stranger would be indirectly influenced by the infant observing a stranger-third party interaction. Subjects were 45 15-month-old infants. Results suggest indirect effects influence social interactions and show that significant others can play an important role in mediating these effects. (Author/RH)

Discusses the significance of emotional communication and social referencing of the mother by her infant as determinants of the infant's affective reactions to other social figures in the environment. (PCB)

Investigated the autonomic reactions (heart rate and skin conductance) of 17 mothers of five-month-old infants to two landscape scenes and four types of videotaped segments depicting their own baby and an unfamiliar baby smiling or crying. (JMB)

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…

Studied effects of strategies used by mothers to prepare a two-year-old child to be left with a stranger. Strategies differed, as did outcomes. Among the results, children given brief preparations remained with the stranger longer and played with more toys. (Author/DB)

This study examined the reactions of 45, 10-month-old infants to peer strangers. The infants were observed in two conditions: with a stranger of the identical age (10 months) and with one who was younger (5 months). In additon, each infant's behavior when he was alone with his mother was compared to his behavior when he was in the presence of…

Whether maternal touching of the infant while speaking to him or her about a stranger facilitates or interferes with social referencing is investigated in this study. Thirty-three 10-month-olds received positive or neutral nonverbal messages when their mothers spoke to them about a stranger. Infants whose mothers did not touch them while speaking…

This study measured infant responses to mother and stranger as a function of mother and stranger distance. A group of 10-month-old infants were pretested for level of object permanence and person permanence, and 18 males and 18 females were chosen as study participants. The infants were randomly assigned to one of three treatment groups: (1)…

This study examined techniques which facilitate children's separation from their mothers and their move into a novel situation. Subjects were 32 male and 32 female 40- to 48-month-old children. Some children were visited in their homes the night before the experiment. Subjects remained with their mothers in a waiting room for 10 minutes. A…

This study was intended to determine whether differences in maternal attitude and behavior relate to differences in infants' Strange Situation security classification. Subjects for the present study were 38 white middle-class mothers and their normal, 1-year-old infants (20 male, 18 female). Infants who were classified as to the quality of their…
