The present study tested the hypothesis that children's fluency with basic number facts and knowledge of computational strategies, derived from early arithmetic experience, predicts their performance on complex arithmetic problems. First-grade students from United States and Taiwan (N = 152, mean age: 7.3 years) were presented with problems that…

Divergent thinking shows the ability to search for new ideas, which is an important factor contributing to innovation and problem solving. Current divergent thinking tests allow researchers to study children's divergent thinking from the age of 3 years on. This article presents the first measure of divergent thinking that can be used with children…

Prosocial behavior in early childhood is a precursor to later adaptive social functioning. This investigation leveraged mother-reported, physiological, and observational data to examine children's prosocial development from age 2 to age 4 (N = 125). Maternal emotion socialization (ES) strategies and children's parasympathetic regulation have each…

Examined when and how children distinguished deductive and inductive problems. Found that by fourth grade, confidence ratings for deductive problems were higher than those for inductive problems, and responses were faster. Explanations differed as a function of the type of problem. (MOK)

Verbal think-aloud protocols were collected from 60 subjects in 3 age groups ranging from 25 through 81 years. Only 5 percent of the responses were considered wise when rated on the criteria of rich factual and procedural knowledge, lifespan contextualism, relativism, and the recognition and management of uncertainty. Wise responses were equally…

Mothers whose infants varied in early biological characteristics (born at term, n = 120; born at very low birth weight [VLBW], n = 144) were randomized to a target group (n = 133) or developmental feedback comparison group (n = 131) to determine whether learning responsive behaviors would facilitate infant development. The target condition…
