scientific community was abuzz when researcher Amalia Bastos first met Kanzi the bonobo in 2023. Kanzi had gained fame for his ability to communicate with humans using a keyboard of symbols. Bastos, who was an incoming postdoctoral fellow at Johns Hopkins University at the time, was immediately captivated by Kanzi’s intelligence and communication skills.
During their first interaction, Kanzi pointed at Bastos and another scientist, then proceeded to select symbols on his keyboard that indicated he wanted them to engage in a game of chase and tickle. Amused by Kanzi’s request, the researchers obliged, pretending to chase and tickle each other to the bonobo’s delight. This encounter sparked a question in Bastos’ mind: could Kanzi understand the difference between pretend actions and real ones?
To investigate this question, Bastos designed a study that involved presenting Kanzi with pretend objects in a controlled setting. Drawing inspiration from developmental psychology research in children, the researchers conducted experiments where Kanzi was shown empty cups and a jug, with the researchers pretending to pour juice into the cups. Kanzi was then asked to identify where the juice was, and he consistently pointed to the cup that had not been poured out.
These findings, published in a new study in Science, suggest that bonobos, like Kanzi, have the ability to understand and differentiate between pretend and real objects. Christopher Krupenye, senior author of the paper and an assistant professor at Johns Hopkins, believes that this capacity indicates that bonobos have the ability to imagine and possess rich mental lives beyond the present moment.
While the results were not surprising to Bastos, as there is evidence of similar behavior in chimpanzees, the study sheds light on the cognitive abilities of bonobos. Martin Surbeck, an evolutionary biologist at Harvard University, notes that the study supports the idea that some apes can comprehend pretend objects, although the reasons behind this ability remain unclear.
However, not all researchers are convinced of the implications of the study. Daniel Povinelli, a biology professor at the University of Louisiana at Lafayette, remains skeptical, suggesting that Kanzi’s performance may not necessarily indicate a deep understanding of imaginary objects in the human sense.
Despite differing opinions, the study highlights the importance of understanding animal cognition and the capacity for imagination in non-human species. As Kanzi passed away last year, future studies will not involve him, but the legacy of his contributions to research on bonobo cognition lives on.
Co-author Krupenye hopes that this study will inspire further research into animal cognition, particularly in endangered species like bonobos. By unraveling the mysteries of animal minds, researchers can gain a deeper appreciation for the complexities of non-human intelligence and foster a greater understanding of the world we share with these remarkable creatures.
