Smartphones reduce our attention span

Our brains have a very advanced concept of time. They are able to predict future events as we engage in our daily activities. For instance, the brain determines the best time to stretch your hand for a handshake—just so your hand will meet the other person’s hand at the right moment.

Our brains also apply this concept of time when we interact with our smartphones. For instance, if you check your phone every five minutes, your brain soon predicts this behavior and reminds you to check your phone at five-minute intervals.

How often do you check your phone?
