Chimptastic.
Yes, studies have shown that chimpanzees can beat adult humans in specific cognitive tests, particularly those measuring working memory and rapid visual assessment. This finding challenges the assumption that humans are superior in all cognitive functions.
Key Study Details
The most famous research, led by Professor Tetsuro Matsuzawa at Kyoto University, involved a short-term memory test where subjects had to remember the location of numbers on a touchscreen:
The Task: Participants were shown the numbers 1 through 9 spread randomly on a computer screen. When the number one was touched, the other numbers were immediately replaced by white squares. The goal was to touch the squares in the correct ascending numerical order based on their original location.
The Results: Young, trained chimpanzees, particularly a chimp named Ayumu, consistently outperformed human adults (including university students) in speed and accuracy, especially when the numbers were displayed for a very short duration (as little as 210 milliseconds). Humans struggled to maintain the same level of accuracy at high speeds.
The Interpretation: The chimps’ success is attributed to an ability akin to photographic or eidetic memory, which allows them to quickly memorize a complex visual pattern at a glance.
The “Cognitive Trade-Off” Theory
Researchers propose a “cognitive trade-off” hypothesis to explain these results. This theory suggests that during human evolution, we may have lost some ancestral short-term or working memory skills to make room in the brain for other, more complex functions, such as advanced language abilities, symbolic representation, and hierarchical thinking. For chimps in the wild, the ability to rapidly remember the location of resources (like a fruit tree) or assess a threat is a critical survival skill.
Other Areas of Superiority
In addition to the memory tests, chimpanzees have also shown an edge in some basic strategizing and game theory tasks, sometimes learning games faster and performing at a level consistent with the theoretical optimum (Nash equilibrium).
While these findings highlight specific cognitive areas where chimps excel, they do not imply overall intellectual superiority. Instead, they demonstrate that intelligence manifests in different ways across species depending on evolutionary needs.
