Orangutans prefer food associated with sounds of laughter, study suggests

New research indicates that orangutans may use emotional cues from their peers to guide decision-making, particularly when selecting food rewards.

The findings highlight how these great apes may rely on auditory signals of happiness to influence their own choices. The study could offer insights into how social dynamics shape learning in primates.
