MIT Study Finds ChatGPT Use Lowers Neural Engagement in Essay Writing

  • Researchers at MIT conducted a study over several months in the Boston area involving 54 participants aged 18 to 39 to measure brain activity using EEG during essay writing with or without AI.
  • The study arose amid growing use of AI chatbots, with concern that early reliance may cause shallow encoding and impair cognitive development, especially in younger users.
  • Participants who used ChatGPT showed the lowest brain engagement, produced similar essays lacking original thought, and underperformed in neural, linguistic, and recall tests compared to those writing unaided or using search engines.
  • Researchers highlighted concerns that early use of AI tools may lead to a reduction in learning abilities, while Kosmyna cautioned against implementing initiatives like a 'GPT kindergarten,' warning that such premature policies could pose significant risks to developing brains.
  • The findings, not yet peer reviewed, suggest careful consideration of AI's long-term cognitive impact and support delaying AI use until independent thinking is well established.

A new study by the Massachusetts Institute of Technology (MIT) Media Lab revealed that the use of current Artificial Intelligence (IA) systems could harm learning, especially among young people.The study divided participants – Boston residents from 18 to 39 years old – into three groups, and asked them to write 20-minute essays using ChatGPT, Google, or without any extra tools. Through an electroencephalogram, researchers recorded brain activity…
