How AI Chatbots Increase Our Cognitive Load, Study Finds
2 minutes read
A recent study explored how interacting with large language model (LLM) chatbots, like ChatGPT, affects human cognitive load. Researchers found that using these AI tools can actually increase the mental effort required to complete tasks, rather than making them easier as many expect.
In the experiment, participants were asked to solve logic puzzles both with and without the assistance of an LLM chatbot. Surprisingly, those who used the chatbot reported higher levels of cognitive strain. The study suggests that processing and verifying AI-generated information, as well as deciding when to trust or ignore suggestions, adds extra mental steps.
This finding matters because it challenges the assumption that AI always simplifies our work. As LLMs become more integrated into daily life and workplaces, understanding their impact on mental workload is crucial for designing better tools and training users.
