JESSICA It is remarkable that Piaget wrote and published his first scientific paper on his observations of an albino sparrow and by 15 his several publications on mollusks and gained him a reputation among European Zoologists who all believed that he was an adult.

In his work Piaget identified the child’s four stages of mental growth. His researches in developmental psychology and genetic epistemology had one unique goal.


After a semester spent at the University of Zurich where he developed an interest for psychoanalysis and intelligence testing, Piaget spent one year working at the Ecole de la rue de la Grange–aux–Belles, a boy’s institution created by Alfred Binet. There he standardized Burt’s test of intelligence and did his first experimental studies of the growing mind.

The interest of Jean Piaget in cognitive development began when he started working with Theodore Simon in his Paris Laboratory for preparation of intelligence tests. He was required to administer intelligence tests to children in order to try and establish better test norms. During his work, Piaget found himself becoming more interested in the quality of children’s answer to questions rather than how many they got wrong or right. Then Piaget became interested with reasoning process that lay behind the answers that children gave. After that, work of Piaget was solely focused on cognitive development, which he continued to study till his death.

In Paris, Piaget devised and administered reading tests to school children and he became interested in child language development and what types of errors they made. These studies, lead him to explore the reasoning process in children.

Piaget worked on cognitive development of the child. The influence of Jean Piaget’s work has not fallen short of that of Freud. He spent most of his life directing an institute of child development in Geneva.
