Study finds that using a smartphone can lead to mental depletion and poor performance.

Need a mental break? Your phone is not the answer

Using a smartphone to take a break during mentally challenging tasks does not allow the brain to recharge effectively and may result in poorer performance, according to researchers from Rutgers University. 

The experiment assigned participants to solve challenging sets of word puzzles.

Halfway through, some were allowed to take breaks using their smartphones.

Others took breaks using paper or a computer while some took no break at all.

The participants who took phone breaks experienced the highest levels of mental depletion and were among the least capable of solving the puzzles afterwards. Their post-break efficiency and quickness was comparable to those with no break. Their number of word problems solved after the break was slightly better than those who took no break, but worse than all other participants.

Participants who took a break on their smartphone took 19 per cent longer to do the rest of the task and solved 22 per cent fewer problems than those in the other break conditions combined.

“The act of reaching for your phone between tasks, or mid-task, is becoming more commonplace,” said study co-author Associate Professor Terri Kurtzberg. “It is important to know the costs associated with reaching for this device during every spare minute.

“We assume it’s no different from any other break – but the phone may carry increasing levels of distraction that make it difficult to return focused attention to work tasks.

“Phones may have this effect because even just seeing your phone activates thoughts of checking messages, connecting with people, access to ever-refilling information and more, in ways that are different than how we use other screens like computers, and laptops,” she said.

The 414 participants were given sets of 20 word puzzles. Some were given a break halfway through, during which they were told to choose three items to buy within a specific budget, using either their smartphone, a paper circular or a computer. They were told to type or write the reasons for their selections.

    Smartphone is an oxymoron. Nobody who is smart lets them control their life.

    The smartphone is a great tool with fantastic capabilities but as with any other tool they should work for the owner not the other way round. I wouldn't take a chainsaw, power drill or pick axe into a theatre or restaurant nor carry a stepladder when I walk the dog. I have been criticised for not carrying my phone 24/7 but I somehow managed to survive over 50 years on this planet without a mobile. I'm not anti smartphone but I refuse to become a phone slave.

    My smartphone makes me focus on it when it is not doing what I want it to do. I then take to my laptop in order to google for the answer. Thank goodness I still have the cognitive ability to follow the instructions on my laptop - though easier when printed out than reading the screen and I hate the youtube videos! Technology is a necessary evil in today's modern world but has certainly fostered a different way of thinking which I am certain has contributed to cognitive decline.
