EEG revealed significant differences in brain connectivity: Brain-only participants exhibited the strongest, most distributed networks; Search Engine users showed moderate engagement; and LLM users displayed the weakest connectivity. Cognitive activity scaled down in relation to external tool use.
Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels.
I am an awful proofreader. My problem has always been that I am blind to the mistakes. I mean grammar and usage type things. I really though an LLM would help me with that but it causes more problems than it fixes so I quit using it.
