If you want to take a break and recharge from mentally challenging work, then it is best not to look at your phone, according to a new study in the United States.
Carried out by researchers at Rutgers University, the new study recruited 414 participants and gave them sets of word puzzles to solve.
Halfway through the task, many participants were given a break with another task involving selecting three items for a hypothetical shopping list either on a cell phone, a computer screen or on paper and writing or typing the reasons for their selections. The rest of the participants were given no break at all.
The findings, published in the Journal of Behavioral Addictions, showed that the participants who took a break with their cell phone showed the highest levels of mental depletion and were among the least capable of solving the puzzles quickly and correctly afterward.
More specifically, participants who took a break on their cell phone took 19% longer to complete the rest of the word puzzle task and solved 22% fewer puzzles than did those in the other break conditions combined.
In fact, the speed and efficiency of the participants who took a break with their phones were comparable to those who took no break.
The researchers say that the results suggest that using a cell phone during a break does not allow the brain to recharge as effectively as the other types of breaks, and could result in poorer performance.
“The act of reaching for your phone between tasks, or mid-task, is becoming more commonplace. It is important to know the costs associated with reaching for this device during every spare minute. We assume it is 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,” said Terri Kurtzberg, co-author of the study.
“Cellphones may have this affect 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 added. HM/JB
