This study examined physiological, emotional, and attentional regulatory functions as predictors of self-regulation in 125 infants followed 7 times from birth to 5 years. Physiological regulation was assessed by neonatal vagal tone and sleep-wake cyclicity; emotion regulation by response to stress at 3, 6, and 12 months; and attention regulation…

Examined association of individual differences in physical maturation with information-processing speed among 9- and 10-year olds. Found that early maturers were faster than late matureres, although this maturity effect was primarily the result of a significant effect for boys. The early maturers' faster processing times may be specific to boys or…

Four experiments tested three to six year olds' and adults' understanding of animals' growth changes. All subjects understood that animals get larger with age. Older children and adults, but not younger children, allowed for dramatic changes in the size and shape of animals over the animals' lifespans. (BC)

This study investigated the progressive development in movement and movement patterns of children ages 2-6. Data were collected over a 3-year period at six-month intervals, based on films of 57 children performing 25 motor tasks. The results are presented along two dimensions: (1) Descriptive analysis of progress of young children in movement with…

This paper presents normative data on height, weight, and body mass in a birth cohort studied prospectively from birth to the age of 7 years. Data are presented by gender and race. The cohort was meant to be representative of the St. Louis metropolitan area in that it included poor people's children, and especially black children who had rarely…

A study of 8 to 35 month olds found that informally employed mothers had more undernourished children than did formally employed or nonworking mothers. With maternal education controlled for, no effects of maternal employment on children's growth patterns were found. Percentage of family income earned by the mother was associated with children's…

Based on the assumption that parents are increasingly aware of the high level of knowledge and skills needed to rear well-adjusted children, this parenting curriculum uses a developmental approach to help parents understand and relate appropriately to child behavior at different ages and at each stage. Part 1, "Before You Start," and the "Leader's…
