摘　　要：Studies estimating eye movements have demonstrated that non-human primates have fixation patterns similar to humans at the first sight of a picture.In the current study,three sets of pictures containing monkeys,humans or both were presented to rhesus monkeys and humans.The eye movements on these pictures by the two species were recorded using a Tobii eye-tracking system.We found that monkeys paid more attention to the head and body in pictures containing monkeys,whereas both monkeys and humans paid more attention to the head in pictures containing humans.The humans always concentrated on the eyes and head in all the pictures,indicating the social role of facial cues in society.Although humans paid more attention to the hands than monkeys,both monkeys and humans were interested in the hands and what was being done with them in the pictures.This may suggest the importance and necessity of hands for survival.Finally,monkeys scored lower in eye-tracking when fixating on the pictures,as if they were less interested in looking at the screen than humans.The locations of fixation in monkeys may provide insight into the role of eye movements in an evolutionary context.Studies estimating eye movements have demonstrated that non-human primates have fixation patterns similar to humans at the first sight of a picture.In the current study,three sets of pictures containing monkeys,humans or both were presented to rhesus monkeys and humans.The eye movements on these pictures by the two species were recorded using a Tobii eye-tracking system.We found that monkeys paid more attention to the head and body in pictures containing monkeys,whereas both monkeys and humans paid more attention to the head in pictures containing humans.The humans always concentrated on the eyes and head in all the pictures,indicating the social role of facial cues in society.Although humans paid more attention to the hands than monkeys,both monkeys and humans were interested in the hands and what was being done with them in the pictures.This may suggest the importance and necessity of hands for survival.Finally,monkeys scored lower in eye-tracking when fixating on the pictures,as if they were less interested in looking at the screen than humans.The locations of fixation in monkeys may provide insight into the role of eye movements in an evolutionary context.
