> We assigned participants to three groups: LLM group, Search Engine group, Brain-only group ... to write an essay. We recruited a total of 54 participants...
> We used electroencephalography (EEG) to record participants' brain activity in order to assess their cognitive engagement and cognitive load, and to gain a deeper understanding of neural activations during the essay writing task. We performed NLP analysis, and we interviewed each participant after each session. We performed scoring with the help from the human teachers and an AI judge (a specially built AI agent).
> We discovered a consistent homogeneity across the Named Entities Recognition (NERs), n-grams, ontology of topics within each group. EEG analysis presented robust evidence that LLM, Search Engine and Brain-only groups had significantly different neural connectivity patterns, reflecting divergent cognitive strategies. Brain connectivity systematically scaled down with the amount of external support...
And then: "...in this study we demonstrate the pressing matter of a likely decrease in learning skills based on the results of our study."
I'm not sure "likely decrease in learning skills" is quite right here.
