Differences in socioeconomic status (SES) correlate both with differences in cognitive development and in brain structure. Associations between SES and brain measures such as cortical surface area and cortical thickness mediate differences in cognitive skills such as executive function and language. However, causal accounts that link SES, brain,…

Performance on a range of spatial and mathematics tasks was measured in a sample of 1592 students in kindergarten, third grade, and sixth grade. In a previously published analysis of these data, performance was analyzed by grade only. In the present analyses, we examined whether the relations between spatial skill and mathematics skill differed…

We examined whether attained socioeconomic status (SES) moderated genetic and environmental sources of individual differences in cognitive performance using pooled data from 9 adult twin studies. Prior work concerning SES moderation of cognitive performance has focused on rearing SES. The current adult sample of 12,196 individuals (aged 27-98…

Functional neuroimaging may provide insights into the achievement gap in reading skill commonly observed across socioeconomic status (SES). Brain activation during reading tasks is known to be associated with individual differences in children's phonological language skills. By selecting children of equivalent phonological skill, yet diverse…

Multiple factors contribute to individual differences in reading ability. The two most thoroughly examined are socioeconomic status (SES) and phonological awareness (PA). Although these factors are often investigated individually, they are rarely considered together. Here we propose that SES systematically influences the relationship between PA…

This report presents two research studies. The first, an experiment using 176 fifth graders, tested three hypotheses: (1) When content is held constant across messages, different formats of a medium differentially call for mental skills. (2) Formats which call for the same skills in different ways affect learners differently. (3) The TV formats…

Perceptions of the school learning environment were examined in relation to three independent variables: the number of fith graders in the school, the percentage of girls of the total number, and the composite SES level. (CK)

Numerous studies indicate age and sex differences in adolescent interests and self-concept development; however, few longitudinal studies have been conducted outside the area of vocational interests. It was hypothesized that an examination of data from both cross-sectional and longitudinal samples would clarify age and sex differences in the…

Cognitive control over impulsive behavior on a Luria-type task was examined for 165 middle- and lower-socioeconomic status (SES) children in nursery school and first grade. Specific impulse control problems were found for both middle- and lower-SES children in nursery school. By first grade, only the lower-SES children continued to exhibit this…

Two experiments comprised this study comparing the ability of children from ages 4 to 12 years to discriminate the order in which items from a previously presented sequence of stimuli had been presented. The hypotheses were that the discrimination of recency (DR) improves with age, that broader separations of test items are easier to discriminate…

The major emphasis of this study is on the comparative validities of paired-associate learning tests and IQ tests in predicting reading achievement. The study engages in a brief review of earlier research in order to examine the validity of two assumptions--that the construction and/or the use of a tactic that simplifies a learning task is one of…

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…
