GoKawiilThe soft ping or buzz on your phone that lets you know a new message has arrived is hard to ignore. But it can mean trouble when it's time to concentrate on a task, according to a new study that will be published in the June issue of the journal Computers in Human Behavior.
The study found that whenever we receive a message notification, it interrupts our concentration for 7 seconds. It turns out that the type of information that we see in the notification also matters. The more personally relevant the notification, the larger the distraction.
"This interruption likely arises from several mechanisms, such as [a notification's] perceptual prominence, the conditioning acquired through repeated exposure, and the possible social significance," Hippolyte Fournier, a postdoctoral fellow at the University of Lausanne in Switzerland and the study's first author, told CNET.
While 7 seconds may not seem like much, we get a lot of notifications throughout the day, and those seconds can add up.
"We observed that both the volume of notifications and how often individuals check their smartphones were linked to greater disruption," Fournier said. "This pattern suggests that the fragmented nature of smartphone use, rather than simply total usage duration, may be a key factor in understanding how digital technologies influence attentional processes."
Attention hijack
The study used a Stroop task, a test that measures how quickly you can process information and how well you can focus. Colored words flash across a screen for the test. The font of each word is one color, but the text of the word is a different color. So the word "blue" might be written in green font.
You have to identify the font color and ignore the color that the word spells out. It's a lot harder than it sounds. You can take the test yourself using this YouTube video.
The researchers recruited 180 university students for the study. The students were randomly split up into three groups. All students received a Stroop task, and notifications popped up on the screen as they completed the test. But the researchers slightly changed the experiment for each group.
The researchers told the first group that the screen was mirroring their personal phones, so the students thought they were seeing their real notifications.
