The Sensory-Motor Stage is a non-linguistic period in which critical pre-language concepts are developed.
I do know a grandmother, however, who never finished the 6th grade. She reads vehemently, nevertheless, and has a vast reserve of concepts which helps her to see the world in as many dimensions as a college graduate.
Piaget’s four stages of intellectual development are:
- SENSORY-MOTOR
- PRE-OPERATIONAL
- CONCRETE OPERATIONS
- FORMAL OPERATIONS
Sensory-Motor Stage (0 - 2 years): This is analogous to Kephart’s Motor Stage. It is a non-linguistic time of life, but it is a mighty busy time as the child prepares for the advent of language.
During this period very many basic concepts about the world are acquired; and indeed, some in particular are essential to the development of language.
