You might think you're doing yourself a favor if you leave your phone behind when you head to an important meeting or dinner with the in-laws, but a new study suggests just the opposite is true.
According to new research from the University of Missouri, being separated from your iPhone can lead to "physiological anxiety" and "poor cognitive performance." The study, "The Extended iSelf: The Impact of iPhone Separation on Cognition, Emotion, and Physiology," was published online Thursday in the Journal of Computer-Mediated Communication.
Researchers invited a total of 40 iPhone-using participants from three journalism courses at a "large university" in the Midwest. Then, they ran a couple of experiments. First, participants were told to sit in a small room and complete a puzzle while in possession of their phone; then, they were asked to complete another puzzle, but they were told that their phone was causing "Bluetooth interference" and that they needed to be moved elsewhere in the room. Researchers then called the phones, study participants could see and hear them ringing, but were unable to get up to answer them.
In each state, researchers kept track of participants' heart rate and blood pressure. You can probably see where this is going: When the puzzle-solvers were separated from their phones but able to see and hear them ringing, they experienced "significant" rises in anxiety, heart rate and blood pressure. They also got worse at completing the puzzle.
In a new release, the researchers suggested that "iPhone users avoid parting with their phones during daily situations that involve a great deal of attention," saying that being apart from the device can make individuals feel "a lessening of 'self.'"
So, what should you do if you own a smartphone but need to focus?
"Our advice would be to carry your iPhone with you," Clayton told HuffPost, "but to silence your phone during cognitively demanding tasks in order to avoid any potential distractions that may reduce your attention throughout the day."
