6-10% of Smartphone Users Display Signs of Internet Addiction

multiple_devicesWe’ve all experienced some of the social and interpersonal disruptions brought on with smartphone overuse; fewer face-to-face conversations, greater distractions, and a certain “hyper-vigilance” an inattention brought out with the anticipation of incoming text messages and phone calls. And all too often, what used to pass for manners and common courtesy has fallen by the wayside.

This recent story from TechRadar.com features interviews with Dr. David Greenfield and psychologist Phil Reed of Swansea University and sheds some new light on the subtle, insidious addictive qualities of smartphone use.

Dr. Greenfield Featured in “Neurology Now” journal

LargeThumbA great source of information on the latest advances in the study of Neurology is the Neurology Now site,  a highly regarded journal for patients and their caregivers published by the American Academy of Neurology.

“It doesn’t matter where you are these days – people are being rude in a way they didn’t used to be. Ignoring you in the car or at a restaurant. Annoying everyone in the cinema. Blanking you at a party.

Smartphone penetration in the UK stands at 71% as of March this year according to data from Kantar Worldpanel ComTech (with similar numbers in developed nations around the world) and that figure is still rising.

People take their smartphones to bed with them, lay them on the table as they eat, and even take them into the toilet.

The manners passed down from generation to generation are being forgotten in a Tweet. It’s not unusual for people to pull a […]
