In one condition, infants were presented with tongue protrusions and mouth openings modeled by an adult. In another condition, these gestures were simulated by objects. Infants in the first condition reproduced the gestures at significant levels, but infants in the second condition did not. Findings indicate that imitation is a social response.…

Examined mothers' and infants' affect in play and infant sex as predictors of infants' response to the still-face situation. (PCB)

Three experiments examined 4- and 6-month-olds' sensitivity to the unity of a partly occluded moving rod undergoing translation, rotation, or oscillation. Findings suggested that all types of common motion were not equivalent for specifying infants' perceptions of occluded objects. (Author)

Evaluated 9-, 14-, and 19-month olds' strategies as they grasped and used spoons presented with the handle alternately oriented to left or right. Found that younger children reached with their preferred hand, disregarding the item's orientation. Older children anticipated the problem, alternated the hand used, and achieved an efficient radial grip…

Three experiments examined the hypothesis that individual differences in look-duration during infancy covary with different modes of visual intake and encoding, with longer look-durations reflecting encoding based on prolonged inspection of local visual properties, and briefer durations reflecting encoding based on a global, or global-to-local…

Examined organization of 5.5, 8.5, and 11.5-month-olds' reaching skill for stationary and moving targets. Found that infants of all ages made anticipatory adjustments of hand alignment; effectiveness of these adjustments improved with age. Regardless of age, infants used dynamic information from spinning and oscillating targets to update ongoing…

Investigated the naive and informed beliefs infant caregivers held about caregiving, using videotaped infant/caregiver interactions and caregiver interviews and writings. Explored the predominance of naive beliefs and the implications for professional education of early childhood teachers. (JPB)

Evaluated changes in mothers' interactive behaviors with infants from 6 to 40 months who were medically high risk, medically low risk, very low birthweight preterm, or full-term. Found that variations in mothers' responses to children's changing capabilities predicted rates of change in children's social skills. (Author/KB)

This study examined the relationship between smile type (basic, Duchenne, duplay) and play type (object, physical, vocal, book reading) during parent-infant videotaped interactions at home. Loglinear analyses revealed that different types of smiles occurred during different types of play more often than expected if distributed equally. Different…

Examined infants' ability to retrieve an object from atop a slightly larger object. Found that even 5-month-olds could retrieve objects close in size and fully contiguous with their bases when demands on reaching skill were reduced. Proposed that when they fail this task, it is because they lack the skill to reach the top object without…

Examined extent to which parent sensitivity, infant affect, and affect regulation at 4 months predicted mother- and father-infant attachment classifications at 1 year. Found that affect regulation and maternal sensitivity discriminated infant-mother attachment groups. The association between maternal sensitivity and infant-mother attachment was…

Used shift-rate recovery method in three experiments to examine extent to which 6-month-olds find perceptual cues such as density and length useful in discrimination of linearly arranged sets of large numbers of objects. Found that infants can discriminate between large number sets by relying on absolute cues such as density and on relative cues…

Outlines the history of and reviews the literature on the care of premature infants. Focuses on the medicalization of birth; early neonatology; the effect of advances in medicine on the survival and safety of neonates; and the importance of early mother-neonate interactions. (BC)

Observed infants' manual gestures while playing with mothers. Infants were more likely than mothers to request objects and less likely to respond to requests for objects. Vocalization accompanying requests increased with age. Infant gazing was most likely during offers that infants initiated without preceding maternal request. Unsolicited offers…

Examined influence of child's sex on mothers' expectations about their 11-month-olds' motor development. Found that mothers of girls underestimated their performance on the novel task of crawling down steep and shallow slopes and mothers of boys overestimated their performance. Girls and boys exhibited identical levels of motor performance during…
