This document summarizes research on digital multitasking and its effects. It defines multitasking and digital natives, and explores both the positive and negative effects of digital multitasking. While some "high media multitaskers" showed increased productivity with distractions, research also linked heavy multitasking to decreased academic performance, increased stress, and lower productivity overall. The verdict is that digital natives should limit multitasking on devices to be happier, healthier and more productive, unless they are among the small percentage that multitask effectively.
