Four experiments investigated whether 9-month-olds could use the presence of labels to help them establish a representation of two distinct objects in a complex object individuation task. Found that the presence of two distinct labels facilitated object individuation, but presence of one label for both objects, two distinct tones, two distinct…

This study examined whether 9.5-month-olds could use featural information to individuate objects. Results suggest that infants categorize events involving opaque and transparent occluders as the same kind of situation and that infants are more likely to give evidence of individuation when they need to reason about one kind of event than when they…

Discusses important recent strides in the documentation and understanding of the infant's learning and memory capacity. Focuses on the psychobiology of learning, hedonic mediation of approach-avoidance and learned behavior, infant memory, and critical conditions of infancy and behavioral misadventures. (RJC)

The interactive behaviors of eight deaf and eight hearing mothers and their hearing infants were examined during play. Compared to hearing mothers, deaf mothers produced fewer, shorter vocalizations, but more nonvocal initiations. The two groups of infants differed on frequency and duration of their vocalizations only at the 16-17 month age level.…

Examined the relation between infant-sibling affective involvement and the attachment security of 1-7-year-old children of 53 mothers. Secure infants reacted less negatively than insecure infants when mothers turned their attention to an older child. (RJC)

Studied individual differences in reactivity in 40 newborns. Measures of reactivity were related during the first two months of extrauterine life. (RJC)

Two groups of infants were studied to demonstrate that changes in reaching are determined by the interaction of organismic and environmental constraints. The infants were placed in three different positions and observed for quantity and quality of reaching. Results indicated that both environmental constraints and growth contribute to reaching in…

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. (HTH)

Two experiments investigated 8-, 10-, and 12-month-old infants' levels of searching for mothers, strangers, and objects. Found that, overall, 10- and 12-month-old infants had higher levels of searching for mothers, whereas youngest infants showed no differences for searching. This discrepancy is likely due to social cognitive development and…

Examined the relationship between infant attractiveness and maternal behavior by observing mothers feeding and playing with their firstborn infants immediately after giving birth and when the infants were three months of age. Found that mothers of more attractive infants were more affectionate and playful compared with mothers of less attractive…

Three studies examined infants' responses to tactile stimulation by adults who offered neutral facial expressions to the infants. Results implied that adult touch and facial expressions act as modulators of infant affect and attention in social exchanges. (BC)

A modified Visual Expectation Paradigm assessed the role of picture content in the spatiotemporal expectations of 80 infants. Stable picture content information facilitated formation of expectations about when and where pictures would appear. Two month olds' reactions were consistently slower than those of three month olds.(LB)

In a study of 20 preterm infants--10 of low socioeconomic status" (SES)--and 33 full-term infants--16 of low SES--from 0;4 through 1;6, premature infants showed reliably less mature vocal patterns than their full-age mates. Premature infants were indistinguishable from full-term infants matched for gestational age in infraphonological…

Used event-related potentials to examine infants' ability to form representations of stimuli presented in a haptic modality and to then recognize these stimuli as familiar when the stimuli were subsequently presented in a visual modality. Found that in certain conditions infants encoded the haptically familiarized object, then transferred their…

Relates the origin and aims of the Special Supplemental Food Program for Women, Infants and Children (WIC) begun in 1972. It has failed to improve the health of newborn children or lower the infant mortality rate, because these problems relate to behavior rather than lack of food. Prenatal care and medical intervention are more appropriate…
