A bagel that needed a few more minutes. And maybe a fact-check.
Summary
This MIT Media Lab study examines the neural and behavioral effects of using AI assistants like ChatGPT for essay writing. Researchers divided participants into three groups: LLM users, search engine users, and brain-only (no tools) users. Using EEG to measure cognitive load, the study tracked participants across multiple sessions, including a crossover session where LLM users switched to brain-only and vice versa. The research investigates how reliance on AI tools affects cognitive processes during writing tasks.

Participants were divided into three groups: LLM, Search Engine, and Brain-only (no tools).
We used electroencephalography (EEG) to assess cognitive load during essay writing.
In a fourth session, LLM users were reassigned to Brain-only group (LLM-to-Brain), and Brain-only users were reassigned to LLM condition (Brain-to-LLM).
