New research suggests a link between short-form video content and negative cognitive changes. A meta-analysis published in Psychological Bulletin, which examined around 70 quantitative studies, found an association between this digital format and poorer cognitive function.
The analysis indicated that the strongest relationships were with attention and impulse control. The research also suggested that individuals who described their short-form video use as compulsive experienced the worst cognitive outcomes.
While the literature is still limited, the authors of the meta-analysis noted that the association with negative cognitive changes was stronger than with poorer mental health. Most of the research reviewed originated from China, where platforms are heavily regulated.
Mark Zuckerberg and other social media executives have previously stated that current science does not support public concern regarding these issues. However, some researchers are increasingly concerned about the cognitive effects of short-form video, which now dominates many social media platforms.
