Be careful about keeping smartphones close to your brain.

Texas (DearPK webdesk news): Experts says that smartphones even in the switched off mode have the capacity to reduce a person’s cognitive ability, making one dumb, according to a new study.  Assistant Professor Adrian Ward and co-authors at McCombs School of Business at The University of Texas at Austin conducted experiments with nearly 800 smartphone users in an attempt to measure, for the first time, how well people can complete tasks when they have their smartphones nearby even when they’re not using them. The smartphone doesn’t even have to ring or vibrate but its mere presence can significantly reduce a person’s cognitive capacity, even when it is switched if it’s off the study said.
The researchers found that participants with their phones in another room significantly outperformed those with their phones on the desk, and they also slightly outperformed those participants who had kept their phones in a pocket or bag.
The findings suggest that the mere presence of one’s smartphone reduces available cognitive capacity and impairs cognitive functioning, even though people feel they’re giving their full attention and focus to the task at hand. The researchers found that participants who were the most dependent on their smartphones performed worse compared with their less-dependent peers, but only when they kept their smartphones on the desk or in their pocket or bag.
