Smartphone Use and the Brain: What Research Says About Novelty and Attention
New insights from Jelle Breineberg, a philosophy professor at the University of Copenhagen, suggest that the brain’s quick pull toward fresh information may contribute to phone overuse. The findings appear in the journal Neuroscience of Consciousness, shedding light on why digital devices so easily become a daily habit for many people in North America and beyond.
Breineberg emphasizes that the human brain is wired to seek novelty. The internet’s constant stream of new data, updates, and sensations makes information access feel almost instantaneous. In contrast to printed books, online content continually evolves, providing a dynamic feed that can captivate attention for longer stretches without a natural pause.
Constant exposure to novelty, along with frequent switches between tasks, can create a cognitive environment that is tough for the brain to handle. In this state, concentration can falter, and the sense of being perpetually “on” can become overwhelming. Some individuals come to view this pattern as enjoyable, perceiving the digital pastime as a form of leisure, while others notice it disrupts their ability to obtain information from traditional sources.
To ease mental load, Breineberg recommends deliberate pacing and moderation in digital intake. Slowing processing and reducing the influx of diverse online content can help restore balance. He also advises avoiding unnecessary visits to a multitude of sites and platforms, which often serve as distractions that do not meaningfully contribute to work or recreation.
Historically, researchers have questioned the long-term effects of smartphone use on daily routines and mental health. Earlier studies also explored how much screen time is appropriate for children and whether extended use impacts eyesight. These investigations continue to inform guidelines about healthy digital habits for families and individuals alike.
