A prevailing theory of mathematical problem solving predicts that children will be less accurate solving a + b = c + __ problems versus a + b = __ + c. However, this has never been tested directly. Because of low base rates, information combined from multiple studies can help improve estimation accuracy and precision. This study compared…

In the United States, racial-ethnic differences on tests of school readiness and academic achievement continue. A complete understanding of the origins of racial-ethnic achievement gaps is still lacking. This article describes social equity theory (SET), which proposes that racial-ethnic achievement gaps originate from two kinds of social process,…

The development of gender attitudes in 402 youth (201 firstborn and 201 secondborn siblings) in 201 European American families was examined using data collected on seven occasions across 9 years. Pooling across siblings and using multilevel modeling, we examined gender attitude development from ages 7 to 19. Consistent with an ecological…

Ability to distinguish intention from accident and understanding of unconscious intention were examined in preschool, kindergarten, and third-grade-age children. (Author)

Fatherchild and motherchild engagements were examined longitudinally in relation to children's language and cognitive development at 24 and 36 months. The study involved a raciallyethnically diverse sample of low-income, resident fathers (and their partners) from the National Early Head Start evaluation study (n290). Fatherchild and motherchild…

This study examined variables related to problem-solving approaches of young children, using the theoretical framework provided by Zigler and collaborators in their work on outerdirectedness. Four aspects of outerdirectedness were examined: developmental trends, different types of reinforcement, task difficulty, and pride in accomplishment. (ST)
