Dr. Bryson has been studying monkeys' ability to classify photographs of cats and dogs. After the monkeys became competent at this classifying task, Dr. Bryson found that certain areas of their frontal lobe neurons fired in response to new "catlike" or "doglike" images. This suggests that the monkeys:

Jean Piaget was the first to investigate the perception of the child (1923), determining that progress depends on a qualitative and not a quantitative advance, that is, on the development of intelligence (Evolutionary Psychology).

Rouseau had already said it: "The child is not a miniature adult, just as his mind is not the mind of an adult on a reduced scale."

It is possible that the mechanism of children's thinking works in the following way: it begins by forming images that correspond to their particular needs (egocentrism) and then to socialization (in their relationship with others), so that their mental capacity will improve with exercising her fantasy (stories), as well as her motor skills, improve with outdoor games.

Analogously occurs in this study of monkeys.
