HAVE you ever heard of the "popcorn brain?" Behind this amusing term lies a worrying reality: our brain's increasing difficulty in concentrating on a single task due to excessive exposure to screens.
With the advent of digital technology, our brains are under severe strain. Constantly solicited by a multitude of stimuli, the brain sometimes struggles to keep up with the frenetic pace imposed by screen-based technology. And it's in this context that the term "popcorn brain" was coined.
"Popcorn brain" describes our brain's tendency to jump from one piece of information to another, without ever settling on a single thing. Like popcorn kernels bursting in all directions, our attention becomes scattered, making it increasingly difficult to concentrate.
This phenomenon appears to be mainly linked to our daily exposure to screens. According to the latest edition of the Ipsos Junior Connect study, surveying over 4,000 children and teenagers in France, young French people (aged 13-19) own an average of three personal screen-based devices. The under-6s even spend six hours a week online, watching videos, chatting with friends and family, listening to music or playing video games. The 7-12 age group spends nine hours a week online, while the 13 plus group spends almost 18 hours a week online.
According to the latest Digital Report 2024 from We Are Social and Meltwater, the typical internet user spends an average of 6 hours and 40 minutes online every day, three minutes more than a year ago.
47-second attention span
This overexposure to screens can have harmful consequences on our attention spans. A Japanese study, published in 2023 in the journal JAMA Pediatrics, and conducted on 7,097 children, established a link between screen time at age one and developmental delays - particularly in the areas of communication, gross and fine motor skills, problem-solving and personal and social skills - at ages two and four.
So how can this phenomenon be explained? According to Gloria Mark, professor emerita of informatics at the University of California, Irvine, our brains are constantly on the lookout for rewards. And screens, with their notifications, colourful images and varied content, are an inexhaustible source of gratification. The result: our brains become addicted to this constant stimulation and find it hard to be satisfied with a less stimulating activity.
"I call these attention traps because they're engaging, rewarding ... and very easy to fall into! We find when people go on TikTok and find a hilarious video they want to stay there because they're looking for that next hilarious video. And that's a lot more rewarding than doing housework or whatever you need to be doing. That's the trap," she explains in an article posted by the University of California.
Over the past few decades, this over-stimulation has led to a decline in our attention spans and concentration.
