"A 'ding' for a text.
"A 'ping' for a Facebook post.
"A 40-second blast from 'Can’t Stop the Feeling!' for a call.
"A growing body of research suggests notifications from smartphones can cause distraction, inattention and even anxiety.
"Kostadin Kushlev at the University of Virginia and Jason Proulx and Elizabeth Dunn at the University of British Columbia looked into the effects of the habitual use of digital devices.
"Polls show smartphone owners spend about two hours per day using their devices, which have dramatically changed how people receive and share information.
"Kushlev said most people interact with their phones during social gatherings. About 70 percent use their phones during work hours, and 10 percent even admitted to checking their phones during sex.
"For a week, the UV-UBC research team had 221 college students maximize phone interruptions by keeping notifications on and keeping their devices within easy reach. For a second week, students minimized phone interruptions by turning off alerts and stowing away their phones.
"During the week of more intense phone interruptions, students reported higher levels of inattention and hyperactivity — distraction, difficulty focusing, fidgeting, boredom and difficulty tackling quiet tasks and activities.
"The findings, Kushlev said, suggest constant digital stimulation 'may be contributing to an increasingly problematic deficit of attention in modern society.'
"The researcher, who presented the study at a conference in California in May, emphasized this problem has a simple solution: The phones can be silenced or turned off."
