“Orangutans Prefer Food Linked to Laughter Sounds, Study Finds” — what this page in the network covers. Orangutans may use the emotional reactions of their peers to guide their own food choices, according to new research on captive apes. Scientists found that when orangutans heard recordings of other orangutans laughing before searching a bowl for a treat, they showed a stronger preference for that food compared to when they heard no laughter or other sounds. The study suggests that positive social cues, like laughter, can influence how orangutans evaluate food quality, hinting that emotions play a role in their learning and decision-making.
The findings add to growing evidence that great apes are sensitive to the emotional states of others, not just in social interactions but also in foraging contexts. This could have implications for understanding the evolution of social learning and emotional contagion in primates, including humans.
