A September review of 71 studies with a total of nearly 100,000 participants found that heavy consumption of short-form video was associated with poorer cognition, especially in regard to attention spans and impulse control, based on a combination of behavioral tests and self-reported data.
The review, published in Psychological Bulletin, a journal of the American Psychological Association, also found links between heavy consumption of the videos and increased symptoms of depression, anxiety, stress and loneliness.
