Performance Goes Down When People are Separated from Their iPhones

Performance Goes Down When People are Separated from Their iPhones

One could argue that people's smartphones are an extension of themselves—these devices hold so much of ourselves from reminders for important occasions to phone numbers that if we didn't have them, part of our minds would become inaccessible, like a focused form of amnesia. So, what happens when you take someone's smartphone away? Erin Blakemore from the Smithsonian writes on a study that answers just this question.

Researchers from the University of Missouri wanted to know how people performed when their iPhones were taken away from them. So, they found 41 students--quite a small sample--that owned iPhones through a survey on “media usage.” These participants were then put in a cubicle (with their iPhones in tow) to solve a series of word search puzzles. Researcher monitored their anxiety levels, heart rate, and blood pressure during this first part.

The researchers then announced that the participants' iPhones were causing Bluetooth interference with the blood pressure cuffs, so they had to move their phones. The smartphones were placed nearby, within earshot of the participants. While the participants continued to work on the word search puzzles, the researchers called their phones, during which time they noted the participants' anxiety levels, heart rates, and blood pressures. There was a “significant increase” in all three and a decline in puzzle performance.

Russell Clayton, a graduate student at the university's School of Journalism and lead author of the study, said in the paper:

"Our findings suggest that iPhone separation can negatively impact performance on mental tasks. Additionally, the results from our study suggest that iPhones are capable of becoming an extension of our selves such that when separated, we experience a lessening of 'self' and a negative physiological state."

This may help explain why we become so distraught when our smartphones become lost or accidentally left behind when we go to work—a part of us feels like it's missing. Some have been even reported feeling “phantom vibrations” while away from their phones.

What does kindness look like? It wears a mask.

Northwell Health CEO Michael Dowling has an important favor to ask of the American people.

Sponsored by Northwell Health
  • Michael Dowling is president and CEO of Northwell Health, the largest health care system in New York state. In this PSA, speaking as someone whose company has seen more COVID-19 patients than any other in the country, Dowling implores Americans to wear masks—not only for their own health, but for the health of those around them.
  • The CDC reports that there have been close to 7.9 million cases of coronavirus reported in the United States since January. Around 216,000 people have died from the virus so far with hundreds more added to the tally every day. Several labs around the world are working on solutions, but there is currently no vaccine for COVID-19.
  • The most basic thing that everyone can do to help slow the spread is to practice social distancing, wash your hands, and to wear a mask. The CDC recommends that everyone ages two and up wear a mask that is two or more layers of material and that covers the nose, mouth, and chin. Gaiters and face shields have been shown to be less effective at blocking droplets. Homemade face coverings are acceptable, but wearers should make sure they are constructed out of the proper materials and that they are washed between uses. Wearing a mask is the most important thing you can do to save lives in your community.

Surprising Science
  • Hungarian astronomers have proven the existence of two "pseudo-satellites" in orbit around the earth.
  • These dust clouds were first discovered in the sixties, but are so difficult to spot that scientists have debated their existence since then.
  • The findings may be used to decide where to put satellites in the future and will have to be considered when interplanetary space missions are undertaken.

Millennials reconsidering finances and future under COVID-19

A new survey found that 27 percent of millennials are saving more money due to the pandemic, but most can't stay within their budgets.

Personal Growth
  • Millennials have been labeled the "unluckiest generation in U.S. history" after the one-two financial punch of the Great Recession and the pandemic shutdowns.
