Even Babies Feel Stressed Looking at Snakes or Spiders (image)

Caption
When the babies saw a snake or a spider (second row) instead of a flower or a fish (first row) of the same size and colour, their pupils enlarged significantly (red versus green curve). This is a distinct signal that they felt stressed looking at these animals.
