Four studies assessed a cognitive explanation for development of infants' preference for attractive faces: cognitive averaging and preferences for mathematically averaged faces, or prototypes. Findings indicated that adults and 6-month olds prefer prototypical, mathematically averaged faces and that 6-month olds can abstract the central tendency…

Examined relationship between emotion regulation at ages 5, 10, and 18 months, and compliance at 30 months. Found that infants with low levels of regulatory behavior were more likely to be noncompliant as toddlers. High cardiac vagal tone was related to noncompliance to toy clean-up, whereas low cardiac vagal tone was related to noncompliance to…

The effectiveness of a live-in nursery program for women inmates is studied. Measurement standards were determined and tested to establish a known base line in the first two years. Goals of the nursery program in Nebraska and profiles of inmates are presented. Cost issues are addressed. (Author/EMK)

Three experiments investigated whether 4-month-olds would attend to and utilize the global configuration ("good form") of a partly occluded, moving object to perceive its unit and coherence behind the occluder. Results indicated that curvature per se provided information in support of completion, in addition to global configuration and…

Examined differences in acoustic characteristics of cries, both early and late, within a prolonged crying bout. Results indicated that late cries appeared to result from a smaller number of factors than did early cries. Results support notions that crying bouts settle into a regular cry with acoustic features matching a theoretical model of cry…

Three experiments manipulated 3-month-olds' attention to different components of a training display and assessed the effect on retention. Results suggested that increasing or decreasing attention to an item during encoding produces a corresponding increase or decrease in memorability. Findings were consistent with a levels-of-processing account…

Asserts that findings on whether young infants look longer at incorrect addition and subtraction have been inconsistent or negative. Hypothesizes that imprecise ordinal calculating with very small numbers of objects develops in late infancy and that precise calculating develops in early childhood. (Author/KB)

Proposes an amended timetable for the origins of joint visual attention and offers theoretical alternatives for the development of point. Includes discussions of the origins of intentionality, the emergence of joint attention, the transition to pointing comprehension, the signal cues of different joint-attention cues, pointing comprehension, the…

Investigated 4- and 7-month-olds' perception of transparency, using computer-generated achromatic or color displays depicting a semitransparent box occluding the center of a rod. Found that 4-month-olds indicated perception of transparency in color but not in achromatic displays. Seven-month-olds showed some evidence of transparency perception in…

This study investigated whether 9-month-olds used phonotactic cues to segment words from fluent speech. Results suggested that 9-month-olds use probabilistic phonotactics to segment speech into words, and that high- probability between-word clusters are interpreted as both word onsets and word offsets. (Author/KB)

Discusses the importance of cultural sensitivity and specific cultural knowledge when providing care for infants and toddlers. Makes suggestions for responding to cultural differences. Describes dialogue and reflective-thinking strategies for identifying and responding to cultural differences. Asserts that caregivers need diversity training to see…

Examined the nature of numerical knowledge in 5-month-olds to inform the debate whether numerical abilities result from capacities dedicated to numerical cognition or to more general perceptual capacities. Found that 5-month-olds could determine the number of collective entities, moving groups of items, when non-numerical perceptual factors such…

Habituated 2-, 5-, and 8-month-olds to visual stimuli following statistically predictable pattern, then showed the familiar pattern alternating with novel sequence of identical stimuli. Found significantly greater interest in novel sequence at all ages. Results support likelihood of domain general statistical learning in infancy and imply that…

Examined the relation of positive affect to attention and learning in 5-, 7-, and 9-month olds. Found that at all ages positive affect was associated with long look durations and slower learning. Neutral affect was associated with short looks and faster learning. Learning was faster than expected for infants displaying both short looks and neutral…

A preferential looking procedure was used to investigate 7-month-olds' perception of positive and negative affective facial expressions in which a single vocal expression was concordant or discordant with the videotaped facial expression. Results indicated that 7-month-olds discriminated among happy, interested, angry, and sad expressions.…
