Describes the conceptual model of newborn organization underlying the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Argues that while the NBAS allows for the identification of an individual's behavioral repertoire, attempts to synthesize the resulting data have been plagued with difficulties. Briefly outlines an alternative model for…

Utilizes experimental results to discuss the advantages and disadvantages of the Brazelton Neonatal Behavioral Assessment Scale as an instrument for measuring individual (rather than group) differences among infants and notes how these differences contribute to parent-infant interaction. (BH)

Suggests future directions for study of sensitivity and its impact on early psychosocial development: (1) renewed attention to growth of attachment in context of other developing features of the parent-child relationship; (2) factors that moderate impact of sensitivity on developing security; (3) origins of individual differences in sensitivity;…

Compared caregiving activities of Israeli kibbutzim mothers, nonfamilial caregivers, and city homemaker mothers. Found that 5-month-olds differed in exploration and vocalization with different caregivers. Caregiving activities, interactions, and developmental processes provided by kibbutz mothers and "metepelet" (child care specialists)…

Studied the impact of massage three times per week on infants' adjustment to a group care setting. Subjects were infants from at-risk Chilean homes who displayed negative emotional behaviors. Found that massaged infants showed less repetitive crying, more tranquil sleep and muscular relaxation, better social adjustment, and improved feeding…

Examined role of social-referential context in 13- and 18- month-olds' mapping of verbal and nonverbal symbols to object categories. Found that infants at both ages showed evidence of learning both words and sounds when the experimenter produced a label within a familiar naming routine, and failed to learn when labels were emitted from a baby…

Advocates renewed efforts toward assessing attachment on a single continuum of emotional security. Contends that theory is essential to guide attachment assessment and that the constructs of secure base and emotional security provide the needed conceptual foundation. Addresses challenges to the scoring of attachment on a security continuum.…

Two experiments examined problem solving in 16-month-olds' adaptive locomotion (crossing bridges of varying width with/without handrail). Findings indicated that toddlers attempted wide bridges more than narrow ones. Attempts on narrow bridges depended on handrail presence. Toddlers had longer latencies, examined bridge/handrail more closely, and…

Two studies examined the impact of temporal synchrony on infants' learning of and memory for sight-sound pairs. Findings indicated that 7-month-olds had no difficulty learning auditory-visual pairs regardless of temporal synchrony, remembering them 10 minutes later and 1 week later. Three-month-olds showed poorer learning in no-synchrony than in…

Examined maternal and infant behaviors, behavioral coordination, maternal response, and nonresponse in relation to security of attachment. Subjects were 40 Euro-American mothers and 39 Central American immigrant mothers studied when their infants were 4-, 8-, and 12-months-old. Found that individual differences on measures of maternal response and…

Explored relation between infants' early spontaneous imitation of novel and familiar words and subsequent lexicons in longitudinal sample between 13 and 21 months. Found marked contrasts in quantity and proportions of nouns between reported and observed lexicons. When earlier vocabulary levels were controlled, infants' early replication of novel…

The effect of prenatal cocaine exposure on gaze of neonates and recovery of gaze of 2-month old infants (n=11) was studied. Compared to nonexposed controls, cocaine-exposed neonates had shorter gaze, and 2-month-old exposed infants had longer gaze. (Author/SW)

Developmental psychologist Ainsworth discusses early influences on her work in attachment theory; similarities and differences in attachment behaviors across cultures; construction of assessments and research designs; individual differences in attachment and maternal support; and the influence of early relationships on later ones.

Two experiments studied whether altering an auditory stimulus' rate of change affected infants' fixation of changing visual stimuli. Results demonstrated that infants exposed simultaneously to auditory and visual stimulation showed a reduced tendency to fixate on relatively more visually stimulating events. Heart rates also accelerated during…
