Neuroscience is contributing to an understanding of the biological bases of human
intelligence differences. This work is principally being conducted along two empirical fronts …

Individual differences in human intelligence, as assessed using cognitive test scores, have a
well-replicated, hierarchical phenotypic covariance structure. They are substantially stable …

Individual differences in intelligence (cognitive abilities) are a prominent aspect of human
psychology, and play a substantial role in influencing important life outcomes. Their …

Human mental abilities, such as intelligence, are complex and profoundly important, both in
a practical sense and for what they imply about the human condition. Understanding these …

Genetic influences on brain morphology and IQ are well studied. A variety of sophisticated
brain-mapping approaches relating genetic influences on brain structure and intelligence …

What is the neurobiological basis of human intelligence? The brains of some people seem
to be more efficient than those of others. Understanding the biological foundations of these …

Nature as well as nurture contributes to the development of individual differences in
intelligence. Genetic research on intelligence has moved beyond this rudimentary nature …

More is known about the genetics of intelligence than about any other trait, behavioral or
biological, which is selectively reviewed in this article. Two of the most interesting genetic …

This article provides an overview of the biometric and molecular genetic studies of human
psychometric intelligence. In the biometric research, special attention is given to the …

What makes one person more intellectually able than another? Can the entire distribution of
human intelligence be accounted for by just one general factor? Is intelligence supported by …
