TLDR: A new study investigated whether short-term exposure to narrow AI tools, like ChatGPT, improves cognitive abilities or merely optimizes task performance. Thirty young adults completed problem-solving and verbal comprehension tasks, either with or without AI support. While AI-assisted participants completed tasks faster and more accurately, no significant changes were observed in their core cognitive abilities as measured by standardized neuropsychological assessments. The findings suggest that AI acts as a ‘cognitive scaffold,’ enhancing efficiency without fundamentally transforming underlying mental capacities, highlighting the need for ethical frameworks that promote critical thinking alongside AI integration.
A recent study titled Efficiency Without Cognitive Change: Evidence from Human Interaction with Narrow AI Systems by MarÃa Angélica BenÃtez, RocÃo Candela Ceballos, Karina Del Valle, Mundo Araujo SofÃa, SofÃa Evangelina Victorio Villaroel, and Nadia Justel, delves into a fundamental question: does integrating artificial intelligence (AI) into our daily lives merely make us more efficient, or does it fundamentally change how we think?
The researchers conducted an experiment with thirty young adults over a seven-week period, including a four-week online intervention. Participants were divided into two groups: one that used AI support (specifically ChatGPT) for problem-solving and verbal comprehension tasks, and a control group that completed the same tasks without AI assistance. Standardized neuropsychological assessments were administered before and after the intervention to measure core cognitive abilities.
The study’s findings revealed that participants who used AI completed several tasks faster and more accurately. This was evident in various programmed activities such as crossword puzzles, problem-solving exercises, word-guessing games, and trivia. The AI-assisted group consistently showed superior performance in these tasks, demonstrating significant gains in efficiency and speed.
However, despite these improvements in task performance, the study found no significant differences in standardized measures of problem-solving or verbal comprehension between the AI-assisted and control groups before and after the intervention. Both groups showed some improvements in certain cognitive subtests, which the researchers attributed to general practice effects rather than specific AI influence.
These results suggest that current narrow AI systems act as ‘cognitive scaffolds.’ They extend human performance by offloading lower-level operations, thereby reducing the cognitive load and allowing individuals to allocate their mental resources more effectively. Essentially, AI helps us perform tasks better and faster, but it doesn’t appear to transform our underlying mental capacities or how we think at a fundamental level.
The authors discuss this phenomenon in the context of ‘extended cognition,’ where external tools temporarily expand cognitive capacity. While AI can optimize performance within specific problem areas, it may not necessarily lead to a growth in autonomous cognitive control. This raises important questions about potential ‘cognitive complacency’ in technologically saturated environments, where effortless access to AI solutions might reduce intrinsic motivation for effortful thought.
The study highlights the need for ethical and educational frameworks that encourage critical and autonomous thinking alongside the use of AI. It emphasizes that AI should be seen as a complement to human cognition, rather than a substitute for cognitive effort. Future research, with larger sample sizes and neurocognitive techniques like fMRI or EEG, is recommended to further explore the long-term effects of AI on neural plasticity and the distribution of cognitive labor.

In conclusion, this research provides valuable insights into the human-AI interaction, demonstrating that while AI significantly boosts efficiency and accuracy in tasks, it optimizes ‘how we perform’ rather than ‘how we think.’ This distinction is crucial for developing responsible strategies for integrating AI into education, professional settings, and daily life, ensuring that human adaptability, creativity, and autonomy are preserved.
