Researchers at Zhejiang University in China found that frequent viewing of short-form videos may be harming attention span and self-control.
The 2024 study, published in Frontiers, examined how platforms like TikTok, Instagram Reels, and YouTube Shorts affect cognitive function. The findings suggest that heavy consumption of short videos is linked to weaker executive control and reduced attentional focus.
The study involved 48 regular social media users, who completed questionnaires measuring addictive short-video use, self-control, impulsivity, stress, and attention. Participants also took part in an Attention Network Test while their brain activity was recorded using EEG.
Results showed that individuals who consumed more short-form content tended to score lower on focus and impulse-control measures. EEG data indicated weaker activity in the prefrontal cortex region associated with executive function and attention regulation.
Researchers concluded that a higher tendency toward short-video overuse may negatively affect self-control and attentional performance. While the study does not claim direct brain damage, it highlights a clear correlation between heavy short-form video use and diminished cognitive control, echoing similar findings from other recent research on social media and attention.
