AI causes reduction in users’ brain activity – MIT
A study from the Massachusetts Institute of Technology (Massachusetts Institute of Technology) found that the human brain does not work less hard when using LLM, but its effects continue, which negatively affects mental activity in future work.
The researchers used a limited number of topics for their experiments (one of the restrictions mentioned in the paper [PDF]), Who were asked to write articles on a variety of topics. A set of topics were allowed to use artificial intelligence (Chatgpt was chosen; researchers looked at the presence of a small difference between them and their competitors), and the second allowed to use Google Search, and the third group “Brain” – i.e. production of work without any technology auxiliary devices.
EEG is used in all topics to monitor brain activity to assess cognitive and pregnancy. The researchers found that groups showed different levels of nervous communication, reflecting different strategies that the brain uses to write tasks. The more the support obtained, the less difficult for them to work. EEG analysis showed that the most active gray material belongs to the unified group, with a lower nervous activity in the “search engine group”, and less than among artificial intelligence users.
The study also studied what “ownership” – the authors’ ability to quote what they wrote after that and summarize their work. Ownership levels have decreased dramatically with the increase in the assistance of the topics he received from technology. Few students who use LLM were able to quote what they have written reliably. In addition, the LLM used group produced “statistically homogeneous articles within each topic, indicating a much less deviation compared to other groups.”
It is not surprising, that the visible crust of those who use a search engine or Chatgpt was more active, as “these groups tend to focus on taking out the tools they use”, the paper states.
Long -term effects
After several rounds of writing articles, two other groups of participating topics were formed, including “from the brain to mm” and “LLM-To-Brain”, which indicate that the names were topics that had not had any technological tools in the past able now to use LLM, and then LLM users were arranged to complete “Solo”. “
The researchers found that “the participants in LLM to the brain showed a weaker nervous connection and the highest participation in the alpha and Beta networks; the participants in the brain showed a mm to summon a higher memory, re -involve the spacious occipital and Faraf. […] This indicates that the re -participation supported by artificial intelligence necessitated high levels of cognitive integration, reactivating memory, and controlling from top to bottom. “
In short, humans who use their brains can to address a topic can take advantage of the use of artificial intelligence after They have already dismantled their ideas, experience, knowledge and feelings completely without using technology. But those who use artificial intelligence from the beginning show a decrease in brain activity over time, and they were less able to perform cognitive tasks when they are asked to go to chat.
The paper states, “As we have shown for four months, the performance of the Participants in the LLM group was worse than their counterparts in the brain group only at all levels: nervous, linguistic, [and] Registration.
Limited study
With only a few dozen in the study, the research group was working with a limited sample. Authors admit that it will be necessary to use more volunteers who have a more varied set of backgrounds for more reliable results. However, artificial intelligence is increasingly used in schools, colleges and daily life, the researchers highlighted what describes a “urgent issue” of “a possible decrease in learning skills” that comes as a result of the use of artificial intelligence as a substitute for human brains.
Conclusions
If the direction of using Chatgpt instead of the same human activities to think, taking into account, and continuous summary, it seems likely that the ability to think effectively decreases to the long term. The presence of artificial intelligence adds a context or additional material later in any intellectual observance that results in better results than its use from the beginning.
The use of the search engine on the middle land between the thought without help and the materials created from artificial intelligence, according to the paper. But the need from Google, Microsoft, And others. To include AI generation in user search results (LLM results appear on Serps [search engine results pages]It means that cognitive activity among daily research users may decrease, in case of focusing only on the search results created from artificial intelligence.
The research group states that more study is needed to understand the long -term effects of AIS on the brain, “before identifying LLMS as a positive thing […] Humans. “
