Your cognitive capacity is significantly reduced when your smartphone is within reach \u2014 even if it\u2019s off. That\u2019s the takeaway finding from a new study from the\u00a0McCombs School of Business<\/a>\u00a0at\u00a0The University of Texas at Austin<\/a>.<\/p>\n

McCombs Assistant Professor Adrian Ward<\/a>\u00a0and co-authors 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\u2019re not using them.<\/p>\n

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.<\/p>\n

The tests were geared to measure participants\u2019 available cognitive capacity \u2014 that is, the brain\u2019s 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.<\/div>\n
\n

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\u2019s smartphone reduces available cognitive capacity and impairs cognitive functioning, even though people feel they\u2019re giving their full attention and focus to the task at hand.<\/p>\n

\u201cWe see a linear trend that suggests that as the smartphone becomes more noticeable, participants\u2019 available cognitive capacity decreases,\u201d Ward said. \u201cYour conscious mind isn\u2019t thinking about your smartphone, but that process \u2014 the process of requiring yourself to not think about something \u2014 uses up some of your limited cognitive resources. It\u2019s a brain drain.\u201d<\/p>\n

In another experiment, researchers looked at how a person\u2019s self-reported smartphone dependence \u2014 or how strongly a person feels he or she needs to have a smartphone in order to get through a typical day \u2014 affected cognitive capacity. Participants performed the same series of computer-based tests as the first group and were randomly assigned to keep their smartphones either in sight on the desk face up, in a pocket or bag, or in another room. In this experiment, some participants were also instructed to turn off their phones.<\/p>\n

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.<\/p>\n

Ward and his colleagues also found that it didn\u2019t matter whether a person\u2019s smartphone was turned on or off, or whether it was lying face up or face down on a desk. Having a smartphone within sight or within easy reach reduces a person\u2019s ability to focus and perform tasks because part of their brain is actively working to not pick up or use the phone.<\/p>\n

\u201cIt\u2019s not that participants were distracted because they were getting notifications on their phones,\u201d said Ward. \u201cThe mere presence of their smartphone was enough to reduce their cognitive capacity.\u201d<\/p>\n
