smartphone reduces brain power

A smartphone is a very personal tool people use on a daily basis to communicate with people around the globe. It has become a part and parcel of our life. People now-a-days can imagine life without sleep and food, but they cannot imagine their lives without a smartphone. Smartphones are surely a boon to the humans but, did you know that having a smartphone within sight or within easy reach - even if it is switched off - can reduce your ability to focus and perform tasks because part of the brain is actively working to not pick up or use the phone? 

According to a research, published in the Journal of the Association for Consumer Research, it has been found that the mere presence of one's smartphone reduces available cognitive capacity and impairs cognitive functioning, even though people feel they are giving their full attention and focus to the task at hand. 

The researchers 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 are not using them. In one experiment, 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 the beginning of the test, 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 team 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.

In another experiment with similar tests, 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.

"We see a linear trend that suggests that as the smartphone becomes more noticeable, participants' available cognitive capacity decreases. 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," said Adrian Ward, Assistant Professor at McCombs School of Business at The University of Texas at Austin in the US.

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