While infants investigated a novel toy, their mothers made either facial or vocal expressions that were neutral, happy, or fearful. Results indicated that infants in the fearful-vocal condition looked at their mothers longer, showed less toy proximity, and showed more negative affect than infants in the neutral-vocal condition. Happy-vocal signals…

Analyzed effects of modeling and contingent praise on infant imitation of three responses: motor-with-toy, motor-without-toy, or vocal. Found a systematic increase in the percentages of training and probe models matched by the three 12- to 14-month-olds following introduction of model-and-praise treatment conditions. Nonmatching responses did not…

Reviews literature on attachment process between adopted children and their mothers. Explains empirical research in relation to Bowlby's theoretical formulation of attachment, basic thesis of which is that infants develop affectional bonds at specific ages of their development and, therefore, child's age at time of adoption is important…

Examined whether young infants produced differentially organized hand and arm actions in relation to affective expressions when the infants were presented with social and nonsocial stimuli. (PCB)

Attempted to replicate findings of a previous study which found that mother-toddler interaction during problem solving was related to the child's prior attachment security. Examined the relationship between problem-solving interactions on the one hand, and mother-child interactions at home and infant temperament on the other. (PCB)

Examined three components of the attachment-transmission model in 48 kibbutz dyads from communal and home-based sleeping arrangements. Found that security of infants' attachment relations and autonomy of mothers' attachment representations were associated with higher emotional availability scores. Poorer emotional availability was found in dyads…

Tested 90 infants in the Strange Situation Procedure (SSP) with both parents. Found that mothers' Adult Attachment Interview (AAI) scores predicted infant-mother SSPs and fathers' AAIs predicted infant-father SSPs. Counter to expectation, infant-father SSPs were associated with infant-mother SSPs, which might be explained by the influence of…

Two longitudinal studies examined social-cognitive skill emergence in 9- to 15-month olds, mother-infant interaction regarding joint attentional engagement, and infant's communicative competence. Findings indicated a reliable pattern of social-cognitive skill emergence and that amount of time spent in joint engagement with mothers and mothers' use…

Presented neonates with lexical and grammatical words prepared from natural maternal speech. Found that neonates could categorically discriminate the sets based on a constellation of perceptual cues that distinguished them. Suggested that this ability to discriminate words on basis of multiple acoustic/phonological cues provides a perceptual base…

Examined whether the atypical pattern of brain activity found in infants of depressed mothers generalized to situations not involving the mother. Found that 13- to 15-month-olds of depressed mothers exhibited reduced left--relative to right--frontal activity during baseline and during interactions with mother and familiar experimenter. This…

Investigated from a dynamic systems perspective mutual regulation during naturalistic interaction of mothers with their 4-month-olds. Found that mothers and infants communicated primarily through vocal signals and responses. Levels of contingent responsiveness between partners were significantly associated and occurred within distinct behavioral…

The article examines how infants are first permeated by culture. Building on Thibault (2000), semiogenesis is traced to the joint activity of primary intersubjectivity. Using an African example, analysis shows how--at 14 weeks--an infant already uses culturally specific indicators of "what a caregiver wants." Human predispositions and…

A study of the relationship between pain-relieving drugs given to mothers during labor and delivery and neonatal behavior as assessed by the Brazelton Scales. Tested 44 infants on eight different days during their first month of life. (SDH)

The ability of 1-month-old infants to recognize their mothers visually was explored with the live faces of mother and stranger presented in three different poses: en face (full face), half-profile, and profile. Subjects were 16 infants with normal Apgar scores at birth who were volunteered by their parents after an initial contact in a maternity…
