Outline of Final Research Achievements |
To discriminate non-living and living objects underlies our social behaviors. In humans, such physical and biological knowledge appears even in early development. In order to explore the evolutional foundation of such knowledge, the present study examined whether non-human primates discriminate non-living and living objects based on the causality of motion as reported in human infants. The results showed that Japanese monkeys expected that non-living things did not move without some external effects while living things move also in a self-propelled way. Combined with our previous findings in chimpanzees, these results suggest that non-human primates share some physical and biological knowledge with humans, leading us to figure out the origins of these knowledge underlying social recognition and the similarities/dissimilarities among primates species.
