Jean Piaget

Jean Piaget (August 9, 1896 – September 16, 1980) was a Swiss developmental psychologist, famous for working out a sequence of stages of cognitive development, and notable for his idea that children (and indeed adults) are continually generating theories about the external world (which are kept or dismissed depending on whether we see them working or not in practice).

Biography: early life

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. 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.

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.

The stages of cognitive development

Piaget became 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 adolescence. 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). Advancement 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 view of the child's mind

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 cannot 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 cannot conserve numbers for five items you would be slow to pick up that they can do it for lower 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 playmates and love to play the game of let's pretend.

Influence

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. The philosopher Thomas Kuhn credited Piaget's work in helping him understanding the transition between modes of thought which characterised his theory of paradigm shifts.

Piaget has had a substantial impact on approaches to education. In Conversations with Jean Piaget, he says: "Education, for most people, means trying to lead the child to resemble the typical adult of his society... But for me, education means making creators... You have to make inventors, innovators, not conformists." (Bringuier, 1980, p.132).

Guiteau was sentenced to death, and was executed by hanging on June 30, 1882 in Washington, D.C..

The philosopher Thomas Kuhn credited Piaget's work in helping him understanding the transition between modes of thought which characterised his theory of paradigm shifts. He insisted (with some validity, as is now recognized) that incompetent medical care had really killed the President. 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. Guiteau was found guilty of assassinating Garfield, despite his lawyers raising an insanity defense. 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. Several inserted their unsterilized fingers into the wound to probe for the bullet, and one doctor punctured Garfield's liver in doing so. Seymour Papert used Piaget's work while developing the Logo programming language. Most historians and medical experts now believe that Garfield probably would have survived his wound, had the doctors attending him been more capable.

Piaget also had a considerable impact in the field of computer science and artificial intelligence. The ailing President had been moved to Elberon, a seaside community, in the vain hope that the fresh air and quiet there might aid his recovery. Among others, the philosopher and social theorist Jürgen Habermas has incorporated it into his work, most notably in The Theory of Communicative Action. on Monday September 19, 1881 in Elberon, New Jersey. Piaget's theory of cognitive development has proved influential, notably on the work of Lev Vygotsky and of Lawrence Kohlberg. Garfield became increasingly ill over a period of several weeks due to infection and died 80 days after he was shot, of blood poisoning and bronchial pneumonia at 10:35 p.m. But many children have imaginary playmates and love to play the game of let's pretend. This was not realized at the time, bedframes being relatively rare.

Most people miss that children are theoretical. Alexander Graham Bell devised a metal detector in an attempt to find the bullet, but the metal bedframe Garfield was lying on confused the instrument. Another surprise is if you tell them a magic bunny moved the objects they would conserve higher numbers. The second bullet that struck Garfield lodged in his back and could not be found. By focusing on the fact they cannot conserve numbers for five items you would be slow to pick up that they can do it for lower numbers. Garfield's assassination was instrumental to the passage of the Pendleton Civil Service Reform Act on January 16, 1883. If you reduce the number to three they could conserve numbers. Guiteau was upset because of the rejection of his repeated attempts to be appointed as the United States consul in Paris--a position for which he had absolutely no qualifications--and was mentally ill as well.

For example children may not be able to conserve five checkers spread out and report that there are more checkers. As he was being arrested after the shooting, Guiteau excitedly said, "I am a Stalwart of the Stalwarts! I did it and I want to be arrested! Arthur is President now," which briefly led to unfounded suspicions that Arthur or his supporters had put Guiteau up to the crime. Piaget however used their problem areas to help understand their cognitive growth and development. Blaine. Some people have used his ideas to focus on what children cannot do. The President was walking through Union Station in Washington, D.C., accompanied by Secretary of State James G.

Garfield was shot by Charles J. 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). In his brief term in office, Garfield appointed a single Justice to the Supreme Court of the United States:.

Ironically, the U.S. His father, Arthur, was a professor of medieval literature at the University of Neuchâtel. The 35th ballot saw an even greater groundswell of support from former Blaine and Sherman supporters (Grant's supporters remained unanimously behind the former President), and on the 36th ballot Garfield was nominated, with virtually all of Blaine and Sherman's delegates breaking ranks to vote for the dark horse nominee. He was born in Neuchâtel in the French-speaking part of Switzerland. With neither Grant, Blaine nor Sherman able to win a majority of delegates after the first day of balloting, on the first ballot of the second day (and 34th overall) Wisconsin's delegation suddenly shifted all its votes to Garfield, who was aghast at the thought that he might be trying to thwart his friend Sherman's effort. . Garfield strongly supported Sherman and made a speech formally nominating him, but early balloting made it clear that Sherman would not be the nominee.
