Some psychologists finetuned a Llama-family LLM on some psychology data - “a data set called Psych-101, which contained data from 160 previously published psychology experiments, covering more than 60,000 participants who made more than 10 million choices in total”, so I guess maybe 10 million tokens? That part seems to make sense, but I cannot rightly comprehend the confusion that follows. Some psychology researchers are claiming it has become a model of human cognition? (Because it can imitate the way a psychology study participant answers psychology study questions?) Other psychology researchers are disputing this by testing its reaction time and digit span memory? (Are they administering an iq test? A cranial nerves exam?)
