Groundbreaking Research Reveals Short-Form Video's Impact on Brain and Cognition: A Comprehensive Meta-Analysis by Griffith University
A significant study from Griffith University's Department of Psychology has provided the most comprehensive analysis to date on how short-form video platforms like TikTok, YouTube Shorts, and Instagram Reels are altering human cognition and mental health. Analyzing 71 studies with 98,299 participants, this systematic review and meta-analysis, published in 'Psychological Bulletin,' investigates the relationship between short-form video use and cognitive functions, as well as mental well-being. The research highlights that the high-speed visual stimulation, infinite scrolling, algorithmic recommendations, and personalized content delivery inherent in these platforms constitute an 'addictive design architecture.' Key findings indicate that frequent exposure to fast-paced content leads to habituation, making the brain less responsive to slower tasks, and sensitization, increasing dependence on immediate gratification. This process, driven by the dopamine reward system, is linked to reduced attention span, decreased patience, and shallower thinking, potentially impacting the prefrontal cortex and attention networks.
