Jean Piaget

Jean Piaget (August 9, 1896 – September 16, 1980) was a Swiss development 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).

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.sijmahjfas
