Monkeys and young children share a surprising ability to understand geometry, suggesting that some cognitive foundations of mathematical reasoning are shared across primates. This finding challenges the notion that abstract thought is an all-or-none ability that suddenly appeared in humans. Instead, it implies that human education and culture build upon ancient biological capacities, rather than creating mathematical thinking from scratch.
The study, led by Carnegie Mellon University scientists, involved experiments with eight adult monkeys (four rhesus macaques and four olive baboons), 55 preschoolers (ages 3-6) from the United States, and 77 Indigenous Tsimane' adult volunteers with minimal formal education. Participants were required to complete a matching task using a touchscreen, finding pairs of shapes with the same geometry that might be rotated slightly differently or scaled to different sizes, among a jumble of geometric shapes.
The most surprising finding was that young kids, before receiving any formal math education, were struggling with the task as monkeys do. Correct answers elicited a positive 'bing' sound, with primates and children being given a reward. This suggests that the stronger use of symbolic representation, which humans lean on more heavily, is learned, perhaps through formal education, rather than being an inherent quality of human intelligence.
The study also revealed that children and monkeys tended to rely more on intuitive processing, while adults leaned more heavily on the symbolic approach, unconsciously abstracting the core geometric rules that define similar shapes. This raises a deeper question: Are there other cognitive abilities that we assume are unique to humans, but are actually shared with other primates?
From my perspective, this study is fascinating because it challenges our understanding of human intelligence and the role of education in shaping it. It also suggests that there may be hidden implications for how we approach education and the development of mathematical thinking. Personally, I think it's a reminder that we should be more open to the idea that human intelligence is not a fixed trait, but rather a dynamic and evolving process that is shaped by our environment and experiences.
One thing that immediately stands out is the potential for this research to inform educational practices. If we can better understand the cognitive foundations of mathematical reasoning, we may be able to develop more effective teaching methods that build upon these ancient biological capacities. This could lead to a more intuitive and engaging approach to learning, one that is more aligned with the way our brains are naturally wired.
However, what many people don't realize is that this study also raises important questions about the role of culture and environment in shaping intelligence. The fact that the Tsimane' adults, with minimal formal education, performed as well as the preschoolers suggests that there may be other factors at play, such as cultural practices and social interactions, that contribute to cognitive development.
If you take a step back and think about it, this study also has broader implications for our understanding of evolution and the development of intelligence. It suggests that some cognitive abilities may have evolved independently in different species, but are still connected through shared biological roots. This raises a deeper question: How do we define intelligence, and what are the boundaries between different species?
In my opinion, this study is a fascinating insight into the nature of human intelligence and the role of education in shaping it. It also highlights the importance of considering the broader context in which intelligence develops, including cultural and environmental factors. Personally, I think it's a reminder that we should be more open to the idea that human intelligence is not a fixed trait, but rather a dynamic and evolving process that is shaped by our environment and experiences.
