Smartphones make us less efficient: study

New Delhi: While smartphones help us stay in touch with colleagues, keep on top of our inbox, and complete urgent tasks on the move, they actually make us less productive when we are working at our desks, according to a new psychological experiment by the Universities of Würzburg and Nottingham Trent, reports ANI.

The experiment unearthed a correlation between productivity levels and the distance between the participants and their smartphones. When their smartphones were taken away, their performance improved by 26 percent.


The experiment tested the behavior of 95 persons between 19 and 56 years of age in laboratories at the universities of Würzburg and Nottingham-Trent. Care was taken to balance experimental conditions and gender across laboratory sites.

Researchers asked participants to perform a concentration test under four different circumstances: with their smartphone in their pocket, at their desk, locked in a drawer and removed from the room completely.

The results are significant test results were lowest when the smartphone was on the desk, but with every additional layer of distance between participants and their smartphones, test performance increased. Overall, test results were 26 percent higher when phones were removed from the room.

Contrary to expectations, the absence of the smartphone didn’t make participants nervous.  Anxiety levels were consistent across all experiments. However, in general, women were more anxious than their male counterparts, leading researchers to conclude that anxiety levels at work are not affected by smartphones (or the absence of smartphones), but can be impacted by gender.

“Previous studies have shown that on the one hand, separation from one’s smartphone has negative emotional effects, such as increased anxiety, but, on the other hand, studies have also demonstrated that one’s smartphone may act as an distracter when present. In other words, both the absence and presence of a smartphone could impair concentration”, said Jens Binder from the University of Nottingham Trent.

“In summary, our findings from this study indicate that it is the absence, rather than the presence, of a smartphone that improves concentration,” said Astrid Carolus from the University of Würzburg. The results of the experiment correlate with the findings of an earlier survey named “Digital Amnesia at Work.”
