The baby explores, puts everything in its mouth, discovers new objects. The girl plays house, the boy represents a race with his toy cars. A little later, both turn their attention to the rules of conduct and morality. The more reflective adolescent, on the other hand, can build arguments to counter those of his parents and plan his own future. These are different ways of interacting with the world, which become more complex as the individual grows. In Jean Piaget's work, these mechanisms are called schemas and are considered the engine of knowledge, since they provide mental figures according to new stimuli or experiences.
According to Piaget, based on these schemes, children build the mental structures that enable learning.
