Summary

Chimpanzees follow human gaze to find food but avoid using it when the human cannot see the reward. This suggests complex social cognition beyond simple orientation.

Area of Science:

Primate cognition
Comparative psychology
Animal behavior

Background:

Primates, including chimpanzees, demonstrate gaze following to conspecifics and humans.
The extent to which chimpanzees utilize gaze cues in object-choice tasks for foraging remains unclear.

Purpose of the Study:

To investigate whether chimpanzees use human gaze direction to locate hidden food in an object-choice task.
To differentiate between potential explanations for gaze-following behavior in chimpanzees.

Main Methods:

Six adult female chimpanzees participated in experiments involving gaze-following tasks.
Object-choice tasks utilized three types of occluders: barriers, tubes (transparent), and bowls (opaque).

Main Results:

Chimpanzees successfully used human gaze cues to select containers (tubes, barriers) with visible food.
Gaze following was not employed when choosing between opaque bowls, irrespective of food presence.

Conclusions:

Findings challenge explanations based solely on simple orientation or a "seeing-knowing" understanding.
Results suggest a nuanced form of gaze following, potentially integrating orientation with foraging drives or a rudimentary understanding of visual perception.
