| C2 | Abstract (preprint): adults writing essays with an LLM showed the weakest EEG connectivity, lowest felt ownership and difficulty quoting their own essays; in a fourth session (n = 18) those switched from LLM to no tools showed under-engagement. Outcomes are neural and essay-recall measures, not an unaided test of taught content, so this is indirect support only. |
Review state: first-pass draft, pending human review.

Verified content
- [abstract] 54 participants in sessions 1–3 (LLM, search engine, no tools); 18 completed session 4 with LLM and no-tool groups swapped.
- [abstract] EEG connectivity strongest without tools, moderate with search, weakest with the LLM.
- [abstract] In session 4, those moving from LLM to no tools showed reduced alpha and beta connectivity; those moving from no tools to LLM showed higher memory recall.
- [abstract] LLM users reported the lowest ownership of their essays and struggled to quote their own work accurately.
Limits
- [assessment] Preprint, not peer reviewed; small sample (18 in the crossover session); the outcomes are brain connectivity, essay features and recall of one's own essay, not a learning test on taught content. Widely publicised; useful to have on file so readers can see what it does and does not show.
Why it is in the library
The most publicised study on AI and "cognitive debt". It bears on C2 (outsourcing the work lowers what is kept without the tool) only indirectly: recall of one's own essay is not learning of taught content. Having it in the library with its limits stated helps readers judge claims made about it.
