An innovative curriculum for preschoolers may improve academic performance, reduce diagnoses of attention deficient hyperactivity disorder (ADHD), and close the achievement gap between children from poor families and those from wealthier homes, according to research led by a Vancouver neuroscientist who is an expert on the development of the cognitive functions that depend on the prefrontal cortex area of the brain, called executive functions (EFs).

University of British Columbia Psychiatry Prof. Adele Diamond, who is Canada Research Chair in Developmental Cognitive Neuroscience, led the first evaluation of a curriculum called Tools of the Mind (Tools) that focuses on EFs. These functions include resisting distraction, giving a more considered response instead of your first impulse, working with information you are holding in mind, and the mental flexibility to think “outside the box.” …

“The recent explosion in diagnoses of ADHD may be partly due to some children never learning to exercise attentional control and self-discipline,” says Diamond. “Although some children are strongly biologically predisposed to hyperactivity and wouldn’t benefit from training, others may be misdiagnosed because what they actually need are skills in self-regulation.”

Previous research has shown that EFs are stronger predictors of academic performance than IQ, she adds. Children from lower-income families enter school with disproportionately poor EF skills and fall progressively farther behind in school each year — facts which Diamond says are related and correctible.

“Helping at-risk children improve EF skills early might be critical to closing the achievement gap and reducing societal inequalities. We showed EFs can be improved in preschoolers without fancy equipment and by regular teachers in regular public school classrooms.”

Most interventions target consequences of poor self-control rather than seeking prevention at an early age, as does Tools. “Early intervention – heading off problems before they develop — costs far less and achieves far better results than trying to correct problems once they have developed,” Diamond says.

“If throughout the school-day EFs are supported and progressively challenged, benefits generalize and transfer to new activities. Daily EF ‘exercise’ appears to enhance and accelerate brain development much as physical exercise improves our bodies,” she adds…
