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.
