Visual Processing of Faces in Juvenile Western Lowland Gorillas without the Use of Training or Reinforcement: A Pilot Study

Cognitive research in zoos is often limited by an inability to consistently train and reinforce subjects. This feasibility study aims to address this problem by examining visual processing of faces by Western lowland gorillas (Gorilla gorilla) at a zoo in order to identify gaze patterns without any training or reward.
