ÄJean Piaget(August 9, 1896 – September 16, 1980) was a Swiss developmental psychologist.
He was born in Neuchâtel in the French-speaking part of Switzerland. His father, Arthur, was a professor of medieval literature at the University of Neuchâtel. He was a precocious child and developed an interest in biology, particularly of mollusks, to the point of publishing a number of papers before he graduated from high school.
He received a Ph.D. in natural science from the University of Neuchâtel and studied briefly at the University of Zürich. During this time, he published two philosophical papers which showed the direction of his thinking at the time, but which he later dismissed as adolescent work. His interest in psychoanalysis can also be dated to this period.
He then moved from Switzerland to France, where he taught at the school for boys run by Alfred Binet, the developer of the Binet intelligence test, in Grange-aux-Belles. In 1921, he returned to Switzerland as director of the Rousseau Institute in Geneva.
In 1923, he married Valentine Châtenay, and they had three children, whom he studied from infancy.
He was a professor of psychology at the University of Geneva from 1929 to 1975 and is best known for organizing cognitive development into a series of stages-- the levels of development corresponding to infancy, childhood, and adolesence. These four stages are labeled the Sensorimotor stage, which occurs from birth to age two, (children experience through their senses), the Preoperational stage, which occurs from ages two to seven (motor skills are acquired), the Concrete operational stage, which occurs from ages seven to eleven (children think logically about concrete events), and the Formal Operational stage, which occurs after age eleven (abstract reasoning is developed here). Advance through these levels was explained through biology and culture along with a "third factor" called equilibration, working inter-dependently with the other two.
Piaget's theory of cognitive development has proved influential, notably on the work of Lev Vygotsky and of Lawrence Kohlberg. Among others, the philosopher and social theorist Jürgen Habermas has incorporated it into his work, most notably in The Theory of Communicative Action. Piaget also had a considerable impact in the field of computer science and artificial intelligence. Seymour Papert used Piaget's work while developing the Logo programming language. Alan Kay used Piaget's theories as the basis for the Dynabook programming system concept, which was first discussed within the confines of the Xerox Palo Alto Research Center, or Xerox PARC. These discussions led to the development of the Alto prototype, which explored for the first time all the elements of the graphical user interface (GUI), and influenced the creation of user interfaces in the 1980's and beyond.
His long scientific career began in 1907 at the age of eleven with the publication of a short paper on the albino sparrow. Over the next seven decades he wrote more than sixty books and several hundred articles.
Piaget viewed children as little philosophers and scientists building their own individual theories of knowledge. Some people have used his ideas to focus on what children can not do. Piaget however used their problem areas to help understand their cognitive growth and development. For example children may not be able to conserve five checkers spread out and report that there are more checkers. If you reduce the number to three they could conserve numbers. By focusing on the fact they can not conserve numbers for five items you would be slow to pick up that they can do it for less numbers. Another surprise is if you tell them a magic bunny moved the objects they would conserve higher numbers. Most people miss that children are theoretical. But many children have imaginary play mates and love to play the game of lets pretend.
