This is a characteristic of the sensorimotor stage (birth to 2 years), where schemas become self-initiated activities. For example, the infant who learns that sucking achieves a pleasing result generalizes the action to suck fingers, blanket, or clothing. Successful achievement leads to greater exploration. By age 6, the child is in the preoperational stage of development. The child is expected to be egocentric, even though language ability is progressing. Play becomes a primary means by which children foster their cognitive development; therefore playing with a doll is considered normal at this age. Children see objects and persons from only one point of viewtheir ownat this stage.
