The Neuroscience of Intelligence

An accessible review of genetic and neuroimaging research that explains what determines intelligence and how we might enhance it.

Why are some people smarter than others? This accessible book explains modern neuroscience techniques and what they reveal about intelligence. It dispels common misconceptions about intelligence testing and discusses how neuroscientific methods could dramatically enhance intelligence, with surprising implications for education and social policy.This new edition provides an accessible guide to advances in neuroscience research and what they reveal about intelligence. Compelling evidence shows that genetics plays a major role as intelligence develops from childhood, and that intelligence test scores correspond strongly to specific features of the brain assessed with neuroimaging. In detailed yet understandable language, Richard J. Haier explains cutting-edge techniques based on DNA and imaging of brain connectivity and function. He dispels common misconceptions – such as the belief that IQ tests are biased or meaningless. Readers will learn about the real possibility of dramatically enhancing intelligence and the positive implications this could have for education and social policy. The text also explores potential controversies surrounding neuro-poverty, neuro-socioeconomic status, and the morality of enhancing intelligence for everyone.
