We spend an average of just 47 seconds on any screen before shifting our attention. It takes 25 minutes to bring our attention back to a task after an interruption. And we interrupt ourselves more than we're interrupted by others. In Attention Span, psychologist Gloria Mark reveals these and more surprising results from her decades of research into how technology affects our attention. This book reveals how we can take control, not only to find more success in our careers, but also to find health and wellness in our everyday lives.
