The widespread use of short-video platforms (e.g., TikTok), with over one billion monthly active users worldwide in 2023, necessitates an examination their effects on cognitive functions. We hypothesized that because the frequent, user-driven shifts content during watching, it mainly impairs event segmentation, a critical process continuous perception and memory formation. To investigate this, we integrated encoding-retrieval tasks, eye-tracking technology, self-report questionnaires, advanced machine learning analyses eye movements. Our experiments (Study1 N=113, Study2 N=60), which varied types videos (random vs. personalized) stimuli (continuous movies static images), demonstrated watching randomly selected short videos, particularly when into daily viewing patterns, detrimentally affects encoding, especially initial middle phases encoding. However, this impairment was not evident trial-based image encoding suggesting selective disruption processes. Intersubject correlation (ISC) analysis movements revealed decreased synchronization at boundaries movie after exposure to random videos. Furthermore, Hidden Markov Model (HMM) indicated participants were more likely experience fragmented segmentation following These findings underscore potentially harmful impact formation, emphasizing role recommendation algorithms modulating human cognition.
