The article reports that higher daily time spent on social media among young adolescents is linked to a thinner cerebral cortex, with thinning observed in multiple brain regions related to attention, memory, and emotional control. The study used MRI data from a large sample of 7,614 children aged 10 to 13 and accounted for various demographic and behavioral factors. Findings suggest a relationship between digital habits and physical aspects of brain development during a sensitive developmental period.
This topic is of interest to psychology readers because it connects everyday technology use with measurable brain structure changes, highlighting how social environments and digital behaviors may intersect with developmental processes such as executive function and attention.
