5. Jean Piaget’s Theory of Cognitive
development
Jean piaget (1896-1980) was one of the 20th century ‘s most influential researchers
in the area of developmental psychology.
He originally trained in the area of biology and philosophy and considered
himself a “genetic epistemologist” (genetic=development, epistemologist=study
of knowledge).
Piaget wanted to know how children learned through their development in the
study of knowledge .
Piaget’s theory is based on the idea that the developing child builds cognitive
structures(used to understand and respond to physical environment).
He believed the child's cognitive structure increased with development.
Piaget’s theories of infant development were based on his observations of his
own three children.
