Mere Presence Of A Smartphone Causes ‘Brain Drain,’ Study Finds

AUSTIN — The power that a smartphone wields is even stronger than you’d think. A new study finds that simply having your phone within eyesight makes slows down your brain.

Researchers at the University of Texas at Austin recruited nearly 800 smartphone owners for a set of experiments, hoping to study how well phone users could complete tasks when they had their devices within a close proximity, even if they weren’t actively using them.

Having a smartphone within sight or even in your pocket causes significant “brain drain” by reducing cognitive capacity, a new study finds.

The first experiment conducted had participants complete a variety of computer-based tasks that measured available cognitive capacity i.e., the ability to hold and process data. These tasks required full engagement on the part of the participant.

While all participants were told to place their phone on silent, different participants were randomly instructed to follow additional criteria: placing their phones on the desk face down, in their pocket or bag, or in another room altogether.  

The researchers found that the participants who had their phone in a separate room fared the best on the tasks. The increase in performance was most substantial when compared to those who simply had their phone on their desk.

“We see a linear trend that suggests that as the smartphone becomes more noticeable, participants’ available cognitive capacity decreases,” says lead researcher Adrian Ward, an assistant professor of marketing, in a university press release. “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.”

A second experiment using the same tasks assigned in the first study examined how particpants’ self-measured level of smartphone dependence or how much one feels they need their phone to survive  affected their cognitive capacity.

Participants who were very dependent on their smartphone were found to perform worse on the tasks assigned, unless their phone was in another room.

In other words, having a phone in sight, regardless of whether it’s on or off, reduces one’s ability to focus, largely because part of their brain’s functioning power is diverted toward preventing themselves from using their device.

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

The study’s findings were published in the Journal of the Association for Consumer Research.

  1. I was going to make a comment but then I saw my smartphone over there in the corner and I forgot what I was going to say.

    1. You know, what you said was….uh,…oh look, I was liked on FB. Did I respond to her last week? Oh my gosh, they adopted a baby…that brother of mine, how am I going to respond to that…and I better Pin that or I will never remember…now, about your comment joeyman9

      1. Yep. This crazy behaviour has become so bad.

        I have a friend who was traveling in his car to visit me, a relatively short distance from where I live. He rang me on three separate occasions just to tell me that he’ll be there in 20 minutes, then he’ll be there in 15 minutes, and then that he’s “just five minutes away”. As if I needed a running commentary on something as banal as this.

        I was too polite to say anything to him. I just wondered to myself what this device has done to people’s brains that they feel so compelled to do this kind of nonsense.

    2. Then why not ditch your phone ? Seriously. If you are at that stage of obsession you have a problem. You absolutely CAN survive without one, you know. I’ve never had one and I do so effortlessly.

  2. Our household experience is exactly as the study finds. Our teenagers were having trouble getting through their homework; we made them start leaving their phones in the kitchen, and the problem disappeared.

  3. These people are pathetic. Every bit as much as drug addicts are. They should never have allowed themselves to be consumed by this kind of techno temptation. Anyone who spends more than an hour a day on their phones for whatever reason other than for their job, needs psychological help.

    I have never had a mobile phone, never want one and never intend to get one. I curse the guy who invented them. Because THIS video shows what it has led to ; http://www.renegadetribune.com/welcome-happy-world-everlasting-deceit/
