There was a period when individuals weren't required to be accessible at all hours. News arrived through the mail once or twice daily, and rumors spread via magazines or personal conversations. Those times are no more. The widespread use of smartphones has erased any remaining sense of privacy. Throughout the day, our devices are constantly buzzing with text messages, emails, direct messages, and push notifications fromUber Eats (which explored the use of AI on restaurant food images)Encouraging you to order Chinese food even though you just placed an order from them an hour prior. This continuous stream of alerts can certainly be irritating, but there's a more significant issue at hand. Push notifications are strongly linked to smartphone addiction, and studies indicate that these interruptions are impairing our ability to focus and are actually reducing our overall response times.
In 2022, a group of psychologists from the University of Arkansas and Plymouth University in England asked a set of college students to take cognitive tests while being occasionally interrupted by the sound of a vibrating phone and a computer-generated control tone. The findings, which were shared in a journal, showed...PLOS-One, demonstrated that participants took longer to complete tasks when interrupted by a phone compared to another sound. This aligns with the findings of a 2016 study conducted at the Catholic University of Korea and published inComputational Intelligence and Neuroscience, which revealed that individuals performed tasks more slowly and made more mistakes when distracted by phone alerts. Even more concerning, this is just the beginning of a much larger and hazardous issue.

Bad vibrations
After the debut of the first iPhone in 2007, people quickly adapted to the buzz of their phones, even as an increasing number of apps started sending push notifications daily, or even more often. However, each vibration creates a disruption that interferes with focus and productivity, leading to delays in task completion and even interrupting the flow of thoughts. Another study, released this year, took things a step further by actually quantifying these interruptions. Carried out by a group of French researchers and published inComputers in Human BehaviorThe study revealed that getting a smartphone notification led to an average delay of seven seconds in cognitive processing. Notifications also resulted in participants' pupils expanding, which is an automatic sign of increased emotions such as fear and excitement.
The same research also offered some insights into why a smartphone's vibration might be more distracting than other sounds. The buzz of a smartphone can carry a particularly high degree of perceived importance. In other words, individuals are more inclined to see the sound as requiring their attention. Over time, we've been trained by time-sensitive alerts such as work messages and delivery updates to view the sound of a phone as urgent, making it worth pausing another activity to focus on. Smartphones also elicit an emotional response that other sounds don't, as shown by the fact that people's pupils can widen simply from hearing or feeling their phone vibrate.
How to handle the interruptions
You may think the best approach to avoid being interrupted by phone alerts is simply to disable them, but it's more complicated than that. Here's another study (smartphone notifications are a highly popular subject in behavioral science these days, as you might have noticed), this one released in 2024 in the journalMedia Psychology. In a randomized controlled trial involving more than 200AndroidUsers aged 18 to 30 participated, with half instructed to turn off their smartphone notifications for a week. All participants had their phone activity monitored throughout the week using an app developed by the researchers. Interestingly, the findings showed no substantial difference in overall phone usage between the groups. However, it's important to mention that the French study also noted that the frequency of notifications was more connected to productivity than total usage.screen time (although it's still advisable to remember the 20-20-20 rule).
There's another challenge to turning off notifications: the fear of missing out. Indeed, FOMO is a genuine topic studied in psychology and can cause anxiety levels that are just as distracting as the phone itself. So, what can be done regarding the effect of phones on our efficiency? Unfortunately, there isn't a straightforward solution. Certain strategies might assist you in staying away from your phone more easily, such as keeping it completely out of view, or even better, engaging in an activity that truly interests you. However, given how dependent we've become on smartphones, this might be a situation where we can't live with them, but we also can't live without them.
