In collaboration with Professor Mami Yamaguchi of Chuo University, Professor So Kanazawa of Japan Women's University, and Associate Professor Isamu Motoyoshi of the University of Tokyo, infants aged 3 to 4 months have a special visual world that can no longer be seen after 5 months. I made it clear thatThis allows babies to notice small changes that adults may ignore.
The experiment was conducted using a method called the preference gaze method that infants have.It has been found that babies prefer certain graphic patterns, such as the face, to look longer.By using this to compare the gaze time of multiple photographs, we examined whether the baby would notice a change in the presence or absence of gloss or a change in the reflection of the lighting.As a result, it was found that the change in gloss on the surface of the object became recognizable in 7 to 8 months.On the other hand, it became clear that changes in the lighting environment were not recognized after 5 months, whereas infants aged 3 to 4 months were aware of them.
This result shows that the baby is capturing things in a special visual world.This is the first achievement in the world.Babies may be aware of more subtle changes than adults think, and may be seeing a more varied and mysterious world.
