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…

Notes that early infancy, rather than being a period of helplessness, is a period of active exploration and reciprocal interaction with caregivers. Includes activities caregivers can engage in with infants to stimulate infant sensory abilities. (HTH)

Five experiments examined 15- and 18-month olds' sensitivity to morphosyntactic dependencies. Results indicated that 18-month olds, but not 15-month olds, were sensitive to basic relationship between "is" and "-ing" and that 18-month-olds could track relationships between functor morphemes. Findings were consistent with hypothesis that 18-month…

Two experiments investigated whether 5-month olds would look longer at rotating "drawbridge" appearing to violate physical laws because they knew it was causally impossible. Findings indicated that infants' longer gaze at 180-degree rotations was due to simple perceptual preference for more motion, challenging Baillargeon's (1987) claim…

Two studies examined messages conveyed in infant-directed lullabies and play songs. Findings indicated that adult raters differentiated audio recordings of mothers' lullaby- and play-song-styles with 100% accuracy and performed at above chance level in identifying which music 6-month olds were hearing on silent videotapes. Infants focused…

Examines the experiences of families in which fathers care for their newborn infants when mothers return to work after childbirth. Documents the hours of care provided by fathers while mothers are at work, the simultaneous use of other child-care arrangements, and the average savings per family. Explores three possible motivations for families to…

Examined affective and motoric reactivity hypothesized to be associated with later inhibited and uninhibited behavior. Affect and reactivity were classified at four months. Brain electrical activity was assessed at 9 months, and behavior toward novelty, at 14 months. Found that greater activation in both the left and right frontal hemispheres was…

Four experiments examined 8-month-olds' ability to reason about collections of objects. Findings suggested that infants' expectations about object behavior do not automatically apply to any and all portions of matter within the visual field. The behavior of an entity and infants' prior experience played roles in determining whether infants will…

Familiarized 6- and 8-month-olds with speech sounds from a phonetic continuum, exhibiting a bimodal or unimodal frequency distribution. Found that only infants in the bimodal condition discriminated tokens from the endpoints of the continuum. Results demonstrate that infants are sensitive to the statistical distribution of speech sounds in the…

Tested in six experiments young infants' sensitivity to vowel and gender information in faces and voices. Found that 4.5-month-olds showed no evidence of matching face and voice based on gender, but were able to ignore irrelevant gender information and match based on the vowel. Robust evidence of ability to match based on gender was not evident…

Two experiments examined whether infants are sensitive to holistic combinations of line junctions in 2-D images that adults use to derive overall 3-D structure. Results suggested that 3-month-olds are sensitive to holistic combinations of line junctions that adults use to derive 3-D information but also selectively attend to these 3-D cues in…

Investigated 3-month-olds' categorization of animals and vehicles based on static and dynamic attributes. Found that regardless of viewing static or dynamic displays, infants showed habituation to varying exemplars from the same category, dishabituated to an exemplar from a novel category, and showed a novelty preference for a novel-category…
