Piaget was awarded the Erasmus Prize, for his development of the theory.
Piaget believed that children came to understand the world through four periods. The stages involved were the sensorimotor period, preoperational period, concrete operational period and the formal operational period.
In the sensorimotor period which is the first of the four periods stated above which according to Piaget is the stage that “marks the development of essential spatial abilities and understanding of the world in six substages” (Wekpedia) which are the reflex scheme stage: this occurs from time of birth to one month of age and is associated with the development of relexes. The second sub-stage, is primary circular reaction phase: this occurs from one month of age to four months of age and is associated with the development of habits. The third sub-stage, is the secondary circular reactions phase; this occurs from four to eight months of age and is associated with the development of coordination between vision and prehension. The fourth sub-stage is called the co-ordination of secondary course...
