Human infants possess powerful learning mechanisms used for the acquisition of language. To what extent are these mechanisms domain specific? One well-known infant language learning mechanism is the ability to detect and generalize rule-like similarity patterns, such as ABA or ABB [Marcus, G. F., Vijayan, S., Rao, S. B., & Vishton, P. M. (1999).…

Storytelling is perhaps the most powerful way that human beings organize experience. The practice is timeless and universal. Stories help everyone understand the world and make sense of their lives. Like adults, children use stories to process and reflect on their experiences. Recognizing and responding to the stories that infants and toddlers…

We explore in this study how infants may derive phonetic categories from adult input that are highly variable. Neural networks in the form of self-organizing maps (SOMs; Kohonen, 1989, 1995) were used to simulate unsupervised learning of Mandarin tones. In Simulation 1, we trained the SOMs with syllable-sized continuous F[subscript 0] contours,…

This most recent Iowa Kids Count data book, "Iowa Kids Count 2011: Trends in the Well-Being of Iowa Children," provides data on 20 different indicators of child and family well-being at the United States, Iowa, substate and county level. The annually produced data book presents health, education, welfare and economic data including…

This publication addresses the issue of low birthweight and what state legislatures can do to reduce its incidence, particularly in regard to ensuring prenatal care. Other than prevention of unwanted pregnancies, provison of good prenatal care is the most effective strategy for reducing the number of low birthweight babies. This text describes:…

Infant crying signals distress to potential caretakers who can alleviate the aversive conditions that gave rise to the cry. The cry signal results from coordination among several brain regions that control respiration and vocal cord vibration from which the cry sounds are produced. Previous work has shown a relationship between acoustic…

This hearing contains testimony on the Early Head Start program. Testimony was provided by: (1) a director of a state Head Start Association; (2) directors of Head Start programs; (3) a Head Start parent; (4) Olivia A. Golden, Assistant Secretary, Administration for Children and Families, U.S. Department of Health and Human Services; (5) a state…

This study assessed the quality of caregiver-infant feeding interaction with 3- and 9-month-old infants. Findings on several measures indicated that caregivers appear to be more vigilant to their infants' needs at three months than at nine months, although infants became clearer in their cues by nine months. Maternal personality was not related to…

In Ontario, mothers and their preterm or full-term infants were observed at home when the infants were 8 and 12 months of age. At each visit, the Bayley Scales of Infant Development were administered, and after each visit, observers completed the Maternal Behavior Q-Sort and Ainsworth ratings of maternal sensitivity. Maternal sensitivity and…

A total of 48 mother-infant pairs were observed and rated in face-to-face interaction when the infant was 4 months old, and in the Ainsworth Strange Situation when the infant was 12 months old. Mothers' marital satisfaction and social support, and the involvement and support of the child's father, were assessed. The mothers constituted a low…

This study examined infants' reactions to new people by manipulating the social context in which infants became acquainted with new people. Infants (N=48) met someone new in the presence of another unfamiliar adult and their mothers. The new acquaintance either: (1) chatted and worked on a puzzle with the mother; (2) remained silent and worked on…

This study examined sequential dependencies in behavior of 10 mother-infant dyads recorded when the infants were at 7 and 20 weeks of age in an effort to determine the extent to which individuals behave responsively to their partners during interactions. Ten maternal actions and 10 infant actions were selected in face-to-face interactions. Actions…

DiPietro, Larson, and Porges (1987) found behavioral and physiological differences between breast-fed and bottle-fed newborns. It was suggested that breast-feeding is associated with more optimal physiological organization and with increased irritable reactivity early in the neonatal period. The present study investigated whether breast-fed…

Reports on a portion of a long-term investigation carried out to determine the prognostic significance of newborn behavioral assessments for later development and behavior, in terms of identifying a subpopulation which would be a high risk group. (Author/SDH)
