Watch out! Your phone is damaging your brain

Austin, June 28: Your brain power may be reduced when your smartphone is within reach, affecting your ability to concentrate on a task. Researchers from the University of Texas in US conducted experiments with nearly 800 smartphone users to measure how well people can complete tasks when they have their smartphones nearby even when they are not using them and found that they significantly effects the human brains.

McCombs Assistant Professor Adrian Ward and co-authors conducted experiments for the first time, how well people can complete tasks when they have their smartphones nearby even when they’re not using them.

The researchers asked study participants to sit at a computer and take a series of tests that required full concentration in order to score well. The tests were geared to measure participants’ available cognitive capacity that is, the brain’s ability to hold and process data at any given time. Before beginning, participants were randomly instructed to place their smartphones either on the desk face down, in their pocket or personal bag, or in another room. All participants were instructed to turn their phones to silent.

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.

“We see a linear trend that suggests that as the smartphone becomes more noticeable, participants’ available cognitive capacity decreases,” Ward said. “Your conscious mind isn’t thinking about your smartphone, but that process the process of requiring yourself to not think about something uses up some of your limited cognitive resources. It’s a brain drain.”

In another experiment, researchers looked at how a person’s self-reported smartphone dependence or how strongly a person feels he or she needs to have a smartphone in order to get through a typical day affected cognitive capacity.

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.

“It’s not that participants were distracted because they were getting notifications on their phones,” said Ward. “The mere presence of their smartphone was enough to reduce their cognitive capacity.
