Our obsession with latest technologies like smartphone, tablet or laptop may cause not only distraction, but it may also change our personalities, says an expert.

An estimated 65 per cent of people in the developed world have a smartphone, tablet or laptop. And it is predicted that by 2015, eight in 10 of all people would be connected this way - all the time.

Dr Larry Rosen, professor of psychology at California State University, calls these gadgets wireless mobile devices, or WMDs, and explores their potentially explosive effects in his new book, iDisorder: Understanding Our Obsession with Technology and Overcoming Its Hold on Us.
"We're in the middle of a grand experiment here.

We're at the early stages of understanding a society that carries the world in its pocket. It's good - you can always connect with someone - but it also means you're there, 24 hours a day... Our brains have not developed to be constantly engaged like this," the Independent quoted Rosen as saying.
