income comes to learn about surroundng. sensori motor intellignece, perception, memory, language development. Piaget's thory - 6 stages of sensorimotor intellignce are examind. Processing theory: compres cogition ways in which computers analyze data.

The first major theorist to realize that infants are active learners was _______________.

Jean Piaget

When infants begin to explore the environment through sensory and motor skills, they are displaying what Piaget called _________ intelligence. In number, Piaget described ___________stages of development of this type of intelligence.
