Adam Gazzaley and Larry Rosen--a neuroscientist and a psychologist--explain why our brains aren't built for multitasking and suggest better ways to live in a high-tech world without giving up our modern technology. They explain that our brains are limited in their ability to pay attention. We don't really multitask but rather switch rapidly between tasks. Distractions and interruptions, often technology-related--referred to by the authors as interference--collide with our goal-setting abilities.
