A Day in the Life of Your Brain: Judith Horstman

Are you someone who constantly checks your email? Is the 'Crack-berry' moniker deserved? John Freeman describes the psychology behind compulsive email checking. He explains that the neurological effects of constantly checking your inbox are similar to those of playing a slot machine. "Rather than reward an action every time it is performed, you reward it sometimes, but not in a predictable way," he says. Meanwhile, Judith Horstman, author of Day in the Life of Your Brain, describes the neurological underpinnings for technology use and overuse, including the relationship between screen time and attention span.
