Theory of mind (ToM) allows children to achieve success in the social world by understanding others' minds. A study with 3- to 12-year-olds, however, demonstrates that gains in ToM are linked to decreases in children's desire to engage in performative behaviors associated with health and well-being, such as singing and dancing. One hundred and…

Two studies examined age differences in conditional reasoning. Results indicated that 8-year-olds performed better when antecedents were weakly associated with consequents than on strongly associated antecedent/consequents, with no difference among 11-year-olds. Eight-year-olds did better on ad hoc premises than on causal premises, with no…

Maintains that authors' meta-analytic findings make early competence accounts of theory of mind increasingly unlikely. Asserts that findings argue against executive function expression accounts, including that advocated by Scholl and Leslie (PS532407). Explains that meta-analytic findings directly contradict Scholl and Leslie's predictions…

If human cognitive development advances through a series of broad and general stages, then the child's mind at any developmental point should seem consistent and similar across situations in its maturity level and general style. However, there appear to be factors and conditions that promote homogeneity and heterogeneity in the child's cognitive…

Article is concerned principally with the early acquisition of skills relating to the manipulation of things, though perforce the role of certain social skills is treated in the interest of explicating that topic. (Author/CB)

Factors affecting performance on base-10 tasks were investigated in a series of four studies with a total of 453 children aged 5-7 years. Training in counting-on was found to enhance child performance on base-10 tasks (Studies 2, 3, and 4), while prior knowledge of counting-on (Study 1), trading (Studies 1 and 3), and partitioning (Studies 1 and…

Studied whether disturbances in mothers' metabolism (N=139) during pregnancy may exert long-range effects on neurobehavioral development of singleton progeny. Examined detailed pregnancy and perinatal records of mothers who experienced diabetes in pregnancy and intelligence tests of their offspring, administered at ages 7 to 11 years. All…

The behavioral development of rural Guatemalan infants was assessed shortly after birth on a Neonatal Assessment Scale (NAS) and at 6-, 15-, and 24-months-of-age on a Composite Infant Scale (CIS). Summary variables based on NAS performance poorly predicted later assessed performance even as recently as six months after birth. The CIS modestly…

Assessed parents' beliefs about former Head Start children's abilities and values in academics, sports, and social skills during their kindergarten year. Found that there were ethnic differences in parents' beliefs about children's abilities and future prospects in different areas. Parents' beliefs related to children's attitudes toward school and…

Verbal and behavioral measures of children's knowledge are frequently dissociated. These situations represent a largely untapped but important resource for furthering an understanding of human cognition. In this paper, verbal-behavioral dissociations in children are discussed and analyzed, drawing from a wide range of domains. The article explores…

Calls for a process-oriented approach to study of categorization in infancy. Maintains that further understanding of infant categorization and its changes with development requires a more direct assessment of infants' category formation. Argues that two research directions will enhance understanding of categorization: (1) contextual variations on…
