Researchers from Johns Hopkins University studied bonobos and discovered a common talent with humans – sensing when a friend needs guidance. The apes were shown treats hidden under cups, sometimes while the researcher was watching, and sometimes not. When the treat was found, the ape would point to its location. The results showed that the bonobos pointed more quickly at the cup hiding the treat when the researcher didn’t know which one it was.
This finding reveals cognitive connections between hominins that stretch back millions of years. Psychologists Chris Krupenye and Luke Townrow believe this talent is central to human social behaviors, such as cooperation, communication, and strategic teamwork. The study’s experiments removed elements of group mentality and survival instinct, focusing on individual cognitive functions.
The theory of mind, or understanding others’ mental states and perspectives, has traditionally been thought to be unique to humans. However, the bonobos demonstrated an ability to comprehend two things at once: where the treat was hidden and whether their partner knew its location. This finding suggests that apes may possess similar cognitive capacities as humans.
Future studies will explore the motivations behind the bonobos’ actions, such as whether they aim to change their partner’s mental state or behavior. The research has been published in PNAS and confirms that primates have rich cognitive capabilities often denied them.
