Chimp recognizes face like humanSkill transmits from same ancestors.
Human recognizes faces faster and different way than other creatures. Before everyone thought that this was just our feature but now it has been revealed that chimps finds faces as fast as humans.
It worked out when Japanese Masaki Tomonaga and Tomoka Imura educated three female chimp to find cars, bananas and faces among other pictures. Chimps found their same species faces faster than other pictures.
The wrong way round faces don't show up
Humans face knowing is based on quick perception and the same seems to apply on chimps. Just like humans, chimps recognized faces way worst when the picture was flipped over. Also covering eyes, nose and mouth slowed the performance. Otherwise changing picture black and white didn't really disrupted face recognition. Investigators headache was caused because chimps found faces as fast as bananas. Recognizing fruit fast wasn't about perceiving same kind of whole perspective as face tracking. When pictures were swapped black and white bananas as if disappeared. Chimps could tell that they were bananas because their yellow colour.
Human wins Makak
Suddenly chimps found human faces as sensitive as their species faces. Phenomenon can't be explained only that animals used in test were with their humans a lot. Japanesemakakis faces they didn't recognize fast even thought they were beside their cages. Chimps reacted faster on baby faces than Makaks faces even thought they've never seen babies. Was it about humans or same species, chimps noticed faces better when they were straight toward them and not lateral way. This shows that eye-contact is one maker that makes faces knowledge to chimps. ''These resolutions have to be payed attention to when thinking about increasing social intelligence. Both species might have social way benefit with the way faces informs knowledge'', Tomonag estimates in his research project. Investigation was released by Scientific Reports.
