Diet Linked to Intelligence

People with more of this in their blood did better on intelligence tests. Eating leafy greens helps preserve intelligence over the lifetime, research finds. Leafy greens and other foods contain lutein, a plant pigment that protects the brain from aging. People with … Continue reading

On How Much of Intelligence and Personality is Heritable

Pedigree-based analyses found that genetic differences account for 50–80% of the variation of observable (phenotypic) traits. Personality traits account for 34–48% of the variance being explained by genetic differences. Molecular genetic studies have also found that intelligence and personality variables … Continue reading

Brain metabolism predicts intelligence

A healthy brain is critical to a person’s cognitive abilities, but measuring brain health can be a complicated endeavor. A new study by University of Illinois researchers reports that healthy brain metabolism corresponds with fluid intelligence – a measure of … Continue reading

Brain Activity at Rest Provides Clue to Intelligence

A new study reports our level of brain activity while at rest is linked to our ability to perform well in cognitive tests. The ability of an adult to learn and to perform cognitive tests is directly linked to how … Continue reading

Theory: Flexibility is at the heart of human intelligence

Centuries of study have yielded many theories about how the brain gives rise to human intelligence. Some think it arises from a single region or neural network. Others argue that metabolism is key. A new article makes the case that … Continue reading

Brain Anatomical Network and Intelligence

Intuitively, higher intelligence might be assumed to correspond to more efficient information transfer in the brain, but no direct evidence has been reported from the perspective of brain networks. In this study, we performed extensive analyses to test the hypothesis … Continue reading

The neuroscience of human intelligence differences

Neuroscience is contributing to an understanding of the biological bases of human intelligence differences. This work is principally being conducted along two empirical fronts: genetics — quantitative and molecular — and brain imaging. Quantitative genetic studies have established that there are additive … Continue reading

Nutritional status, brain network organization, and general intelligence

A new study reveals higher levels of monounsaturated fatty acids are linked to greater general intelligence. Nutrition has been linked to cognitive performance, but researchers have not pinpointed what underlies the connection. A new study by University of Illinois researchers … Continue reading

Genius in your Genes

Will studying the genome sequences of very high IQ individuals help us understand the biological basis of intelligence? In 1980, Duke University founded the Talent Identification Program (TIP), a scheme for identifying academically gifted school-age children and nurturing their education … Continue reading

Intelligence doesn’t guarantee an open mind

People with higher cognitive abilities are more likely to learn and apply social stereotypes, research finds. However, the experiments also show that those with higher cognitive abilities more easily unlearn stereotypes when presented with new information. “Superior cognitive abilities are often … Continue reading
