Overview
- The Griffith University meta-analysis pooled 71 studies of 98,299 people and found heavier short‑form viewing was associated with poorer attention and inhibitory control.
- It also linked short‑video use with weaker performance in language, memory and working memory.
- The negative associations held across age groups and across platforms such as TikTok, Instagram and YouTube.
- Researchers and the American Psychological Association cite related risks including higher stress and anxiety, greater social isolation and lower life satisfaction.
- Authors describe the results as correlations rather than proof of causation and hypothesize that fast, highly stimulating feeds promote habituation that undermines sustained focus.
