WhatsApp, SMS, Phone: Constantly be accessed via the smartphone. For concentrated work is the poison, you might say. Discussions on mobile bans in schools are the result. Employers demand: phone, head to. But without the little companion of smartphone users still better off.
A study by researchers at the University of Missouri has shown that the absence of the smartphone can adversely affect the performance of its owners - at least if he can hear the ringing in the distance.
In the experiment, 40 iPhone users were asked to pick out a box of letters words - one with and one without a smartphone near. This blood pressure and heart rate were measured. The subjects thought that as a new wireless blood pressure cuff to be tested. After crossword users should assess how anxious and uncomfortable they felt.

Anxiety at cell phone ringing
Then the researchers told the subjects their smartphone would interfere with the Bluetooth connection of the wireless meter for heart rate and blood pressure and should therefore be placed further away in space. Well, the subjects should again trigger a jumble of letters - a far cry from their smartphone. At the same time, the researchers called them on her cell phone. When the ringing stopped, heart rate and blood pressure were measured. The researchers then the subjects interviewed again as felt.
It turned out that the heart rate and blood pressure of the subjects in the second part of the experiment were significantly higher than in the first test with smartphone. In addition, subjects had more anxiety and felt uncomfortable. Words they found, however, significantly less.
iPhone as an "extension of the self"
"Our findings suggest that a separation from the iPhone negative impact on the performance on mental tasks can have," concludes Russell Clayton, PhD student at the MU School of Journalism and lead author of the study summarizes the results. The researchers recommend iPhone users even to have their device wherever you go, if they are to solve problems in everyday life, requiring alertness. Whether devices from other manufacturers have a similar effect is unclear.
Also, why the lack of iPhone as a negative effect, the researchers could not resolve conclusively. The results would however suggest that the iPhone could become the "extension of ourselves" because we fell in their absence in a negative physiological state. Who can not permanently help his iPhone or want to get a long-term protection therefore probably only one thing in question: Overall, more distance - especially.
