Using ChatGPT too much can reduce brain activity

A new study from the Massachusetts Institute of Technology (MIT) warns that the use of artificial intelligence (AI), especially language models like ChatGPT, in learning may reduce students' ability to think independently and remember.

As millions of students around the world are using AI tools to aid their learning, a recent study published by the MIT Media Lab has raised questions about the "cognitive price" users may have to pay when relying on large language models like ChatGPT, according to Telagraph .

AI helps quickly but can make users... think slowly

The study monitored the electrical activity of 54 students while they wrote essays, dividing them into three groups: one group used ChatGPT, one group used Google to search for information, and the last group wrote completely on their own, without any outside assistance.

Results showed that ChatGPT users showed poorer memory performance, lower brain activity, and weaker mental engagement than the other two groups.

“Over the four months of the study, participants in the ChatGPT group performed worse on every level: neurological, language, and grades,” the team emphasized.

In contrast, the group that did not use any tools had more active brain activity and came up with more creative ideas. The group that used Google showed average levels of engagement.

Convenience at the cost of thinking ability?

Scientists say using AI to help with essay writing may initially save students time and effort, but in the long run, this convenience reduces users' ability to critically evaluate the information and content generated by AI.

This can lead to an “echo chamber effect” where users are only exposed to algorithmically personalized ideas and no longer actively verify information, making them susceptible to being led or limited in their perspective.

“Rather than disappearing, echo chambers have adapted to shape how users interact with the world through AI-curated content. What is considered ‘best’ may be influenced by the interests of the parties that own the model,” the study warns.

As AI becomes more prevalent in education , the study warns that relying solely on AI could undermine critical thinking, creativity, and self-learning – all key skills for future generations.

Experts recommend developing guidelines and frameworks for the controlled use of AI in education, encouraging students to use AI as a support tool, not a thinking crutch.
