Use of human visual attention cues by olive baboons (Papio anubis) in a competitive task
The ability of 4 olive baboons (Papio anubis) to use human gaze cues during a competitive food task was investigated. Three baboons used head orientation as a cue, and 1 individual also used eye direction alone. As the baboons did not receive prior training with gestural cues, their performance suggests that the competitive paradigm may […]
