Jean Piaget

Explanation:

Jean Piaget who was widely known for his works on theory of cognitive development and epistemological is considered as the first theorist to recognise that children and adults had different cognitive processes. His work on cognitive development would later became the bedrock for all other intellectual theories

According to Piaget, cognitive development occurred through the rich interplay of biological processes of maturation, neural development as well as language formation via the interaction of social learning experiences in children through adulthood.

In his work, Piaget's stage theory concluded that there are four stages of cognitive development, which includes:

1. Sensorimotor stage: 0 - 2 years

2. Preoperational stage: 2 -7 years

3. Concrete operational stage: 7 - 11 years

4. Formal Operational stage: 11- 16 and above.

Hence, Jean Piaget was one of the first scientists to theorize that intellectual growth occurs in distinct stages, motivated by an innate need to know.
