ChatGPT & Your Brain: A Psychologist’s View
- A new MIT study suggests that relying on ChatGPT for writing tasks may diminish brain activity and the sense of ownership over the written work.
- Researchers divided 54 participants into three groups of 18.
- The study's neural findings, measured by electroencephalography (EEG), revealed that the brain-only group exhibited a "more extensive and stronger connectivity network" during essay writing.
Discover the latest findings on how relying on ChatGPT for writing impacts brain activity. A groundbreaking MIT study reveals a link between ChatGPT use and reduced brain connectivity, suggesting potential cognitive trade-offs.

ChatGPT Use Linked to Reduced Brain Activity, Study Finds
Updated June 19, 2025
A new MIT study suggests that relying on ChatGPT for writing tasks may diminish brain activity and the sense of ownership over the written work. The research, titled “Your brain on ChatGPT,” compared participants who used the AI tool with those who wrote without assistance. The study highlights the potential cognitive trade-offs associated with using large language models (LLMs).
Researchers divided 54 participants into three groups of 18. One group used ChatGPT, another used a search engine, and a third “brain-only” group had no technological assistance.All participants completed essay-writing tasks across three sessions. A fourth session involved only 18 participants.
The study’s neural findings, measured by electroencephalography (EEG), revealed that the brain-only group exhibited a “more extensive and stronger connectivity network” during essay writing. This suggests that writing without ChatGPT or search engines engages memory and creative thinking more rigorously. The more external help provided, the less brain connectivity was observed.
Interestingly, the search engine group showed the highest activity in visual cortices, indicating active observation, analysis, and filtering of visual content.this activity was not seen in the ChatGPT group, suggesting that LLM users may not analyze and evaluate visual content in the same way. The brain-only group had the highest activity in areas associated with semantic integration, creative ideation, and executive self-monitoring.
Behavioral measures supported these neural findings. The brain-only group demonstrated a greater ability to accurately quote from their essays and reported higher levels of essay ownership. In contrast, 83% of chatgpt users reported difficulty quoting their essays after the first session, even though this decreased to 33% by the third session. By the third session,all participants in the search engine and brain-only groups could quote their essays.
Ownership of the essays also differed significantly. The ChatGPT group reported conflicting feelings of ownership, with a minority claiming full ownership and 50-90% reporting partial ownership. The search engine group showed more stable ownership levels, but still less than the brain-only group. The study also found that the ChatGPT group produced more homogenous essays,challenging the idea that LLMs can serve as a base for individual content creation.
The study indicates that strategic timing in introducing AI tools might potentially be key. Participants in the brain-only group who used an LLM in the fourth session showed a “significant increase in brain connectivity across all EEG frequency bands,” an increase not seen in the group using ChatGPT in three consecutive sessions.This suggests that limited, strategic use of AI could enhance engagement and neural integration.
What’s next
Further research is needed to explore the long-term effects of relying on AI tools like ChatGPT on cognitive skills and creative thinking. Understanding the optimal balance between AI assistance and autonomous thought will be crucial in navigating the evolving landscape of writing and content creation.
