In On Task, he moves from early studies of brain damage to modern neuroscience, from childhood to old age, and from human evolution and genetics to the demands of today's electronic world. This authoritative, sweeping, and marvelously accessible book is a great introduction to the questions, insights, and puzzles of modern scientific thinking.--John Duncan, author of How Intelligence Happens In this engaging and authoritative book, David Badre introduces a critical but unfamiliar aspect of cognitive psychology, affording readers a new perspective on human decision making and behavior.--Matthew Botvinick, Google DeepMind and University College London Getting things done is essential to success in life.
