The Giants Shoulder

#90 Meet The World’s Leading Executive Function Neuroscientist

Jan 29, 2026
Dr. Adele Diamond, a pioneering developmental cognitive neuroscientist who revealed prefrontal cortex activity in infants, talks about executive functions and their role in attention, self-regulation, and learning. She explores ADHD types and misdiagnosis from trauma. Topics include dopamine’s unique prefrontal role, limits of stimulants, nonpharmacological interventions like martial arts and music, and how AI and phones erode sustained focus.

ADVICE

Dose Medication To Cognition, Not Just Behavior

  • When prescribing psychostimulants, evaluate cognitive performance, not only behaviour reported by parents.
  • Avoid dosing to suppress hyperactivity alone because high doses can leave children zoned out and not learning.

Executive Functions Drive Life Outcomes

  • Executive functions are the brain's core control processes used for attention, self-regulation, planning and problem solving.
  • Adele Diamond links executive functions primarily to prefrontal cortex and to success across life domains.

Prefrontal Activity Appears Early

  • Before infant studies, researchers assumed prefrontal cortex was inactive in babies because it matures late.
  • Diamond's work showed prefrontal-related behaviours emerge in infancy, overturning that assumption.
