Many social systems, especially education, have an opportunity to significantly improve individual performance and well-being outcomes by attending to and including brain fitness as part of their approach. Brain fitness, like physical fitness, requires exercise. Brain-based "workout" activities improve cognitive development, and their effects can be seen in academic and professional performance, quality of life, and mental health and well-being. Brain fitness has been shown to produce dramatic academic and social improvements, particularly in school-age education. In the United States, unfortunately, the brain fitness of students is not being systemically addressed. A key measure of the neurocognitive capacities foundational to all learning is called executive function (EF). Research has found that EF is a powerful indicator of not only academic performance and outcomes, but also life outcomes such as career and wealth, relationships, health, well-being, and even public safety. Unfortunately, when schools take too limited an approach and focus mainly on content and achievement scores, these underlying EF cognitive capacities of children to self-regulate, process, integrate, and learn are often unknowingly ignored by well-meaning educators. In this article, a U.S.-based nonprofit, BrainFutures, shares solutions to help schools quickly change course and provide their students with the highest quality education informed by cognitive science.
