Nataliya Kos’myna and other researchers at MIT’s Media Lab share findings from their work on "the cognitive and practical impacts of AI on learning environments." Using brain scans, they compare cognitive activity during an essay-writing task performed with and without the help of LLMs. From the preprint abstract:

While LLMs offer immediate convenience, our findings highlight potential cognitive costs. Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels. These results raise concerns about the long-term educational implications of LLM reliance and underscore the need for deeper inquiry into AI’s role in learning.
