Neuroscience

The surprising history of how studying animal cognition influenced the development of modern human intelligence testing methods.

Can brain scans predict IQ? This article covers what fMRI, MRI, and EEG studies reveal about the neural basis of intelligence -- from brain size and cortical thickness to the P-FIT model and neural efficiency hypothesis.

Discover how the P-FIT model, neural efficiency hypothesis, and white matter pathways explain intelligence. Learn what brain imaging reveals about IQ differences and how neuroscience is redefining what it means to be smart.

Chronic stress shrinks the hippocampus by up to 8%, and children with 4+ ACEs score 5-15 IQ points lower than peers. Explore how trauma, cortisol, and PTSD affect intelligence -- and what recovery looks like.

Fluid intelligence peaks around age 25 and declines steadily, while crystallized intelligence grows into your 60s and 70s. Discover how aging reshapes different IQ components and what neuroscience says about preserving cognitive vitality.

Neuroscience research shows IQ is not fixed at birth. Learn which brain training methods have real evidence behind them, how neuroplasticity supports intelligence gains, and what lifestyle changes can measurably boost cognitive performance.

Research shows IQ predicts about 25% of job performance while emotional intelligence predicts up to 58% of success in leadership roles. Discover what Fortune 500 data, salary research, and longitudinal studies reveal about which type of intelligence drives real-world achievement.

IQ measures reasoning and problem-solving ability while EQ measures emotional awareness and social skills. Discover how these two forms of intelligence differ in their brain science, testing methods, developmental trajectories, and real-world applications.
