University of Heidelberg study links heavy smartphone use to intense brain response to social exclusion

A study led by Robert C. Wolf at the University of Heidelberg has revealed that individuals with excessive smartphone use exhibit distinct brain activity patterns when experiencing social exclusion. Using functional magnetic resonance imaging (fMRI), researchers observed that heavy users showed heightened activity in the right middle cingulate gyrus and the right superior frontal lobe compared to those with average usage.

The findings suggest that for heavy smartphone users, the sensation of being socially excluded—often described as “social pain”—is triggered more rapidly and intensely. The study noted a correlation between these neurological patterns and psychological factors such as Fear of Missing Out (FOMO) and impaired daily functioning. While the research provides insight into how digital connectivity affects socio-cognitive processing, researchers noted the study was small, involving 41 young adults aged 18 to 30.
