Thirty Years of Research on Race Differences in Cognitive Ability
The culture-only (0% genetic–100% environmental) and the hereditarian (50% genetic–50% environmental) models of the causes of mean Black–White differences in cognitive ability are compared and contrasted across 10 categories of evidence: the worldwide distribution of test scores, g factor of mental ability, heritability, brain size and cognitive ability, transracial adoption, racial admixture, ...
متن کاملCommunity Influences on Cognitive Ability
Although the environment determines important individual differences in cognitive ability, most home environment variables that correlate with children's intelligence are more strongly associated with the pleiotropic effects of genes than with causal pathways of environmental transmission. Here, we demonstrate that community variables, a hitherto understudied set of constructs in research on co...

متن کاملGenetic Copy Number Variation and General Cognitive Ability
Differences in genomic structure between individuals are ubiquitous features of human genetic variation. Specific copy number variants (CNVs) have been associated with susceptibility to numerous complex psychiatric disorders, including attention-deficit-hyperactivity disorder, autism-spectrum disorders and schizophrenia. These disorders often display co-morbidity with low intelligence. Rare chr...
متن کاملThe effect of education on cognitive ability.
This paper analyzes whether schooling increases intelligence measured by intelligence quotient (IQ). We use a longitudinal dataset where the individuals have conducted IQ tests both at ages 10 and 20. We estimate the effect of schooling on IQ at age 20 conditional on IQ at age 10 and other measures of early cognitive ability to account for selection into noncompulsory schooling. Ordinary least ...
