A foundational question that we can ask in this domain concerns the frame of reference in which another person's gaze is represented. Electrophysiological recordings in macaque monkeys suggest that direction of gaze might be encoded relative to the observer (i.e., in a first person reference frame) or relative to the head or body of the stimulus (i.e., in a second person reference frame… CONTINUE READING
