Concern Grows That AI Is Damaging Users’ Cognitive Abilities
Sign up to see the future, today Can’t-miss innovations from the bleeding edge of science and tech Last year, a team of researchers led by MIT research scientist Nataliya Kosmyna used electroencephalograms to monitor the brains of students while they were writing short, deliberately open-ended essays. They split the 54 participants into three groups: one was told to use ChatGPT, one could search for information on Google (minus AI-generated summaries), and another had to rely on their own knowledge. As detailed in a resulting yet-to-be-peer-reviewed paper, each group was tasked with writing one essay per month for three months, while a subset of each group was asked to switch to or away from using ChatGPT for a fourth month. The researchers’ EEG findings were ominous: the students using ChatGPT “consistently underperformed at neural, linguistic, and behavioral levels,” they found, and even got lazier with each consecutive essay. “The brain didn’t fall asleep, but there was much less activation in the areas corresponding to creativity and to processing information,” Kosmyna told the BBC in an interview …
