Catherine Price, co-writer of Reclaim your brain newsletter, investigates the science behind excessive phone use. Prof Barbara Sahakian explains why we are drawn to bad news on our phones. Topics include app addiction, the impact of smartphones on attention and memory, negative effects of doomscrolling on mental health and brain function, and strategies to stop doomscrolling and redirect attention.
Excessive phone use and constant app-switching fragment our attention and hinder our ability to sustain focus and form long-term memories.
Doom-scrolling, the compulsive habit of scrolling through negative news, can have detrimental mental health effects and can be countered by changing phone habits and employing techniques to regain control.
Deep dives
The Impact of Phones on Attention and Memory
Our phones and the apps on them fragment our attention and negatively impact our ability to sustain focus. This is because scrolling and app-switching trains us to be more distractible. Moreover, phones and apps interfere with our ability to form long-term memories since distraction interrupts the process of transferring short-term memories to long-term ones.
The Role of Dopamine and Design in Phone Addiction
The release of dopamine in our brains plays a crucial role in our addiction to our phones. Anything that triggers dopamine release, such as bright colors, sounds, or receiving new information, gets interpreted as something worth paying attention to, making us seek it out again. Phone apps, with their use of dopamine triggers and intermittent rewards, are designed to hook users just like slot machines.
Doom-Scrolling, Mental Health, and Breaking the Phone Habit
Doom-scrolling, compulsively scrolling through negative news, can have detrimental mental health effects. It can induce chronic stress, impact brain regions related to fear and anxiety, increase cortisol levels, and shrink certain brain areas. Breaking the phone habit involves changing the phone itself, creating physical distance, and employing techniques such as inserting speed bumps and intentional questioning to regain control over phone usage.
If you’ve made a resolution to spend less time on your phone this year, help is at hand. The Guardian has launched a new newsletter, Reclaim your brain. Its co-writer and expert coach Catherine Price tells Madeleine Finlay how her own excessive phone use inspired her to investigate the science behind our relationships with our devices, and what we know about how to break the cycle. And Prof Barbara Sahakian of Cambridge University explains why many of us are drawn to looking at bad news on our phones, and what it’s doing to us.
