A new review led by Syrine Salouhou and colleagues from University College London and CNRS shows that video games are transforming how scientists study the human mind. By embedding experimental tasks into game-like experiences, researchers can collect rich behavioral data from millions of people outside the lab. The paper, published on arXiv, highlights projects such as Sea Hero Quest and The Music Lab as successful examples.
What the Research Found
Sea Hero Quest, a mobile navigation game, has been played by over 4 million people since 2016. Researchers analyzed gameplay data to study spatial navigation and its link to Alzheimer's disease risk. The Music Lab, a web-based game about musical perception, has gathered data from over 500,000 participants, revealing how culture and age shape musical preferences. According to the review, these citizen science games offer three key benefits: scalability (reaching large, diverse populations), ecological validity (more natural behavior than lab tasks), and public engagement (players learn about science while having fun). The authors also interviewed professional game developers to identify challenges: designing games that are scientifically rigorous, ethically sound, and engaging enough to retain players. They note that such projects remain rare because they require interdisciplinary teams and careful balancing of research goals with entertainment value.
Why It Matters for Your Brain
Understanding how cognition works in real-world conditions—not just in a sterile lab—can lead to better tools for assessing and improving your own memory, attention, and reasoning. Citizen science games allow researchers to see how cognitive abilities vary across different ages, cultures, and lifestyles. This means the findings are more relevant to you, whether you're a student, a professional, or a retiree. For instance, knowing that spatial navigation declines with age but can be slowed through active exploration might motivate you to try new routes or play navigation-based games. The review also highlights that games can test cognitive functions that are hard to measure in short lab tasks, such as sustained attention over hours or creative problem-solving in dynamic environments.
What You Can Do
You can contribute to cognitive science while having fun. Look for publicly available citizen science games like Sea Hero Quest (available on mobile) or play The Music Lab online. These games are free, take only minutes to play, and directly help researchers understand the human mind. Alternatively, consider taking a validated online cognitive test—like the free adaptive IQ test at iqgenio.com—to get personalized insights into your own abilities.
