Great apes track events involving agents and patients, like humans, suggesting shared cognitive mechanisms. When watching video clips, apes alternated their gaze between agents (e.g., a cat) and patients (e.g., a mouse), similar to adult humans, though apes paid more attention to background details. Human infants, in contrast, focused mostly on the background, indicating that event tracking develops later. These findings suggest that the cognitive ability to track agent-patient relationships evolved before language, providing insights into how humans developed this key aspect of communication. ….[READ]
