Study Examines the Impact of Short Videos on Adolescents

A research team has investigated the effects of short videos on platforms such as TikTok, Instagram, and YouTube. The meta-study, conducted by a group of scientists, aims to analyze the potential negative effects of these formats on the cognitive development of adolescents. The lead author of the study, Dr. Anna Müller, emphasizes that the use of these platforms has increased exponentially in recent years. The study shows that adolescents aged 12 to 18 spend several hours daily consuming short videos.

According to the results, 70% of respondents spend more than two hours per day on this content. This high usage duration could lead to brain overload, referred to as "brainrot." A central finding of the investigation is that constant exposure to rapid sequences of images and short snippets of information can impair the ability to concentrate and engage in deep thinking. The researchers found that 65% of adolescents have difficulty focusing on a task for extended periods. This could have long-term effects on academic performance and overall cognitive development.

The meta-study also analyzed the emotional impacts of using short videos. Many adolescents reported an increase in anxiety and depression associated with the use of these platforms. In particular, the constant comparability with other users and the pressure to gain likes and followers contribute to a negative self-image. Another aspect of the study addresses the type of content consumed. The researchers noted that content depicting violence or risky behavior is particularly popular among adolescents.

About 40% of respondents indicated that they regularly watch such videos, raising concerns about the normalization of violence and risky behavior. The study recommends that parents and educators develop greater awareness of the content adolescents consume. Dr. Müller suggests that education about the risks of using short videos should become part of the school curriculum. This could help strengthen adolescents' media literacy and encourage them to engage more responsibly with digital content.

The results of the meta-study were presented at a conference on media psychology and garnered significant interest. Experts from various fields discussed the need for further research on the long-term effects of consuming short videos. The study could serve as a basis for future guidelines on media usage among adolescents. The researchers plan to expand their investigation in the coming years to analyze the effects on different age groups and cultures.

Another focus will be on developing intervention programs aimed at helping adolescents establish healthy media habits. The next phase of the research is set to begin in 2027. The meta-study was published in the journal Journal of Youth Studies and is part of a larger project examining the effects of digital media on youth. The study includes data from over 1,500 adolescents from various regions.
