Drawing on Geary's (1995) evolution-based model of cognitive and academic development, this study investigated the relation between biologically primary skills (vocabulary, executive functions, and visual-spatial processing) and subsequent word reading and calculation. It also examined the extent to which these relations were mediated by…

We examined the relation of parental socioeconomic status (SES) to the neural bases of subtraction in school-age children (9- to 12-year-olds). We independently localized brain regions subserving verbal versus visuo-spatial representations to determine whether the parental SES-related differences in children's reliance on these neural…

Measures of visual and tactual recognition memory, tactual-visual transfer, and object permanence were obtained for preterm and full-term infants. Measures of tactual-visual transfer were correlated with later intelligence measures up to the age of five years. These correlations were independent of socioeconomic status, medical risk, and early…

The study reported here was an attempt to systematically manipulate certain factors which might be responsible for the poor communicational performance of lower socioeconomic status children. The major questions raised were: Can differences in task difficulty, perceptual characteristics of the task, and task instructions attenuate or eliminate…

Socioeconomic status (SES) is strongly associated with cognitive ability and achievement during childhood and beyond. Little is known about the developmental relationships between SES and specific brain systems or their associated cognitive functions. In this study we assessed neurocognitive functioning of kindergarteners from different…
