Japanese macaques form a cross-modal representation of their own species in their first year of life
Primates, 47, 350-354, doi: 10.1007/s10329-006-0182-z
We tested whether infant Japanese macaques (Macaca fuscata) have a cross-modal representation of their own species. We presented monkeys with a photograph of either a monkey or a human face on an LCD monitor after playing back a vocalization of one of those two species. The subjects looked at the monitor longer when a human face was presented after the monkey vocalization than when the same face was presented after human vocalization. This suggests that monkeys recall and expect a monkey’s face upon hearing a monkey’s voice.
