A comparison was made of the behaviors of 64 12-month-old infants in situations where adult female strangers played either an active or a passive role. (Author/JMB)

Examined emotion regulation strategy use in 75 infants between 6 and 18 months during interactions with strangers. Compared to 12- and 18-month olds, the 6-month olds were more likely to use gaze aversion and fussing as their primary regulation strategy and were less likely to use self-soothing and self-distraction.

A reanalysis of first-year longitudinal data suggests that infants' reactions to a stranger up through the middle of the first year are attributed to a wariness of the unfamiliar while by 9 months, learned aversions which have their roots in prior disturbing experiences may become an important additional determinant. (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)

Uses the habituation paradigm to investigate 3-month-old infants' abilities to recognize and discriminate among the faces of strangers. Infants consistently discriminated between photographs of faces following extensive exposure to one, and recognized something about the face they saw during habituation. Results suggest that similarity influences…

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)

This article reviews the literature on infants' reactions to strangers, focusing on issues of assessment, reliability, and stability. (JMB)

Investigated three-month-olds' abilities to discriminate and recognize smiling and frowning expressions of mothers and strangers. Discrimination and recognition occurred regardless of the adult who was involved; however, more infants discriminated the mothers' expressions than the strangers', and boys looked at their mothers' faces longer than did…

A total of 87 infants 10 months of age received, either directly or indirectly, a positive nonverbal message, a neutral nonverbal message, or no message about a stranger. Infants, especially those with easy temperaments, were friendlier to the stranger when mothers had spoken positively, but only when the message was directly communicated.…

Aims of study were (1) test for independence in infant's attachment to parent, (2) test concept of security by viewing infants judged secure versus insecure with mother in situation designed to arouse apprehension, (3) examine effects of infant-parent relationships upon positive responsiveness to new persons, and (4) identify characteristics of…

Mothers' emotion and personality characteristics were assessed by behavior ratings and self-reports; infants' characteristics by maternal reports and objective coding. Security of infant-mother attachment in the Ainsworth Strange Situation was predicted by mothers' emotional experience, expressive behavior, and personality traits, and by infants'…

Discusses observations of sets of infant twins, aged 6 to 24 months, as they interacted with one another and with an unfamiliar peer. Assesses quality of infant-mother attachment. Finds twins are more likely to react with one another than with a peer. Results are discussed in relation to early peer relationships and attachment. (Author/RWB)
