| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Humans are afraid of specific stimuli, such as angry faces and snakes. It has been a long debate on whether such fear responses are acquired through learning or an innate one. A series of our studies demonstrated that a picture of snake among those of flowers was also quickly detected by human adults. We also found that even young children of three years old detected a picture of snake among flower pictures, which suggests that humans are innately sensitive to snakes. Further, we found that macaque monkeys reared in a laboratory with no experience with snakes also detected snake pictures quickly. These results strongly suggest that snakes and/or angry face are phylogenetic fear-relevant stimuli, and that the exaggerated sensitivity to snakes by humans and monkeys have evolutional routes. A hypothesis and our on-going studies suggest scale is the key to snake fear. | |
