Groundbreaking Research on Ape Cognition
A recent study conducted by researchers at Johns Hopkins University has revealed that Kanzi, a 43-year-old bonobo, can engage in pretend play, a cognitive ability previously thought to be exclusive to humans. Published on February 5, 2026, in the journal *Science*, the research challenges long-held beliefs about the limits of animal cognition and suggests that the roots of imagination may extend back 6 to 9 million years to a common ancestor shared by humans and other apes.
The Tea Party Experiments
The study involved a series of controlled experiments designed to test Kanzi's ability to track imaginary objects. In the first experiment, Kanzi was presented with two clear cups and an empty pitcher. The experimenter pretended to pour imaginary juice into both cups and then acted as if they emptied one. When asked, “Where’s the juice?” Kanzi consistently pointed to the cup that was supposed to still contain the pretend juice, demonstrating an understanding of the imaginary scenario.
In a follow-up test, one cup contained real juice while the other held only imaginary juice. Kanzi was asked which he preferred, and he almost always selected the cup with real juice, indicating he understood the difference between the two. A third task involved pretending to take a grape from an empty container and placing it into one of two jars. Kanzi again indicated the correct location of the pretend grape, achieving results above chance.
Implications for Understanding Animal Cognition
The findings suggest that Kanzi possesses the ability to conceive of objects that are not physically present, a cognitive skill that could reshape our understanding of animal intelligence. Co-author Christopher Krupenye emphasized the significance of these results, stating, “Imagination has long been seen as a critical element of what it is to be human, but the idea that it may not be exclusive to our species is really transformative.”
Criticism & Opposition
While the study presents compelling evidence, some critics may argue that the results do not definitively prove that Kanzi's understanding of pretense is equivalent to human imagination. Skeptics might point out that the experiments were conducted in a controlled environment, which may not fully capture the complexities of natural behaviors in wild apes.
Future Research Directions
The researchers plan to explore additional aspects of imagination in apes, including whether they can think about future events or consider the thoughts of others. Krupenye remarked, “If some roots of imagination are shared with apes, that should make people question their assumption that other animals are just living robotic lifestyles constrained to the present.”

- “It really is game-changing that their mental lives go beyond the here and now,” — Christopher Krupenye, Assistant Professor, Johns Hopkins University
- “It’s extremely striking and very exciting that the data seem to suggest that apes, in their minds, can conceive of things that are not there,” — Amalia Bastos, Former Postdoctoral Fellow, Johns Hopkins University
The study of Kanzi not only enhances our understanding of ape cognition but also invites a reevaluation of what it means to be human in the context of imagination and mental life.
