Two experiments used paired-comparisons to investigate 3-month olds' recognition of dynamic visual events after various retention intervals. Results indicated a changing pattern of attentional preferences over time consistent with models of infant recognition memory in which novelty, familiarity, and null preferences are considered conjointly and…

Summarizes findings on infants' capacity for object segregation. Maintains that infants can use featural and experiential information for segregation and individuation purposes long before 12 months of age. Disputes the claim that formation of object categories awaits early word learning, but acknowledges that language may play a key role in…

Four experiments examined whether reinstatement and reactivation reminder paradigms affected memory performance of 102 three-month-olds. Results indicated that a single reinstatement protracted retention twice as long after training as a single reactivation. The novelty of the reminder stimulus also affected duration and specificity of memory in…

Studying normal infant development is a challenge for cognitive scientists in general and for neuroscientists in particular because: (1) physiological indices of infant cognition are generally noisy and technically difficult to obtain; and (2) interindividual variability and a paucity of established results make data interpretation very complex,…

The authors examined the relationship between newborn neurobehavioral profiles and the characteristics of early mother-infant interaction in Nagasaki, Japan. The authors administered the Brazelton Neonatal Behavioral Assessment Scale (NBAS; T. B. Brazelton & J. K. Nugent, 1995) in the newborn period and the Nursing Child Assessment Teaching…

The ''ba, ba, ba'' sound universal to babies' babbling around 7 months captures scientific attention because it provides insights into the mechanisms underlying language acquisition and vestiges of its evolutionary origins. Yet the prevailing mystery is what is the biological basis of babbling, with one hypothesis being that it is a non-linguistic…

Background: The present study was designed to investigate the association between visual exploratory behaviour in early infancy, novelty seeking in adolescence, and the dopamine D4 receptor (DRD4) genotype. Methods: Visual attention was measured in 232 three-month-old infants (114 males, 118 females) from a prospective longitudinal study using a…

To determine whether parents in families that live in high-risk environments accurately complete developmental questionnaires to be used in identifying infants at-risk for developmental delay, this study evaluated 54 at-risk and 43 nonrisk parent-infant dyads. Risk dyads included those living in extreme poverty and those with mothers whose…

A 36-item observation instrument was developed for measuring appropriate social development in infants and toddlers. Checklist items indicated such behaviors as asking, protecting, comforting, lending, sharing, hugging, playing with, joining, laughing, smiling, looking at, performing request, leading, following, and conversing. Use of the…

The conferencee discussions and papers presented in this volume reflect the opinions and research of 20 authorities in the field of communication development. These authorities offer new perspectives on nonverbal communication, speech reception and production, and the development of language and thought. To provide a better understanding of…

The Nurse-Parent Training Project, developed in cooperation with Children's Hospital of Buffalo (New York), was designed to provide developmental supportive care for premature infants, and to reduce stress while optimizing neurobehavioral development. A program was conducted to train nurses working in neonatal intensive care nurseries, to enable…

This study explores cultural influences in the first three months of life by comparing the daily experiences of first generation Chinese-American and European-American infants whose parents were born in the United States. The study focused on 10 Chinese-American and 10 European-American families whose mothers were recruited during the third…

Outcomes of a follow-up, preventive care program based on a self-regulation model of neonate and parent behavior were studied in a controlled experiment. Subjects included a preterm control group, preterm intervention group, and full-term control group, with each group consisting of 27 infants. The assessment, which used the Brazelton Neonatal…

Prior to considering the ability of infants to think, this discussion attempts to dispel prevalent myths about babies' thought processes. The fact that infants do not intentionally manipulate their parents; are not identical; are not simply hedonistic seekers of bodily pleasures; and are not passive, disorganized beings needing training into…

A study of the effect of the twin sibling relationship upon interactions between monkey mothers and infants. Findings provided strong support for the prediction that the twin sibling presence decreases the amount of behavior directed from infant to mother. Differences in maternal behavior were concluded to be reactions to differences in infant…
