Some experts think these subtle changes are causing great harm to our neurological well-being.
Gary Small and Gigi Vorgan made a series of dramatic claims about the way digital devices are rewiring young brains in their 2008 book “
iBrain, Surviving the Technological Alteration of the Modern Mind.”
Most of their assertions aren't pretty. Given that adults commonly consume two, three or even more gadgets at once now -- all while carrying on conversations with people – they are beginning to lose their ability to focus and concentrate, they say. They describe a phenomenon called "continuous partial attention," a state of divided attention which leaves people unable to perform tasks that require concentration. Worse, it leaves its victims less and less able to connect with and empathize with each other, they said.
