A new study from the Massachusetts Institute of Technology (MIT) suggests that reliance on artificial intelligence chatbots may lead to reduced brain activity and impaired memory. The research, led by scientist Nataliya Kosmyna, found that students using ChatGPT showed up to 55% less brain activation compared to those who wrote essays without AI assistance.
The study involved 54 students divided into three groups: one used ChatGPT, another used Google search without AI summaries, and a third used no technology. Brainwave measurements revealed that the ChatGPT group had significantly less activity in areas associated with creativity and information processing. Additionally, these students struggled to recall their essays and felt little ownership over the work.
Kosmyna noted that the findings, while not yet peer-reviewed, align with other research indicating that AI tools can lead to 'cognitive surrender'—a tendency to accept AI outputs without critical scrutiny. A separate study from the University of Pennsylvania observed similar effects, where users allowed AI to override their own intuition.
Experts warn that this 'cognitive offloading' to AI could have long-term consequences, particularly for young people. Previous research has shown that over-reliance on technology, such as search engines, can reduce memory retention—a phenomenon known as 'the Google effect'. The growing use of AI chatbots may exacerbate these effects, potentially impacting critical thinking and problem-solving skills.
