New study shows iPhone users addicted to devices

A new study says many iPhone users are both psychologically and physiologically addicted to their devices.

University of Missouri researchers found that iPhone users assigned to do a simple word puzzle, had a drop in performance, when their devices were taken away.

They also had a significant jump in blood pressure, heart rate, and anxiety.

Researchers say the study shows people are becoming so attached to their phones, that they experience a lessening of "self" and a negative physiological state when they're separated from them.
