Piaget's theory of cognitive development proposes that humans gradually acquire and construct knowledge through four stages of development from birth through adulthood. The theory deals with how we understand reality and gain knowledge through transformations and states. Piaget argued that assimilation and accommodation are how we perceive new information and alter pre-existing ideas. The four stages are the sensorimotor stage from birth to acquiring language, the pre-operational stage from ages 2 to 7, the concrete operational stage from ages 7 to 11, and the formal operational stage from ages 11 to 15-20 involving abstract thought and problem solving.

development (1896¨C1980)
? Piaget's theory of cognitive
development is a comprehensive
theory about the nature and
development of human intelligence.
? The theory deals with the nature of
knowledge itself and how humans
gradually come to acquire,
construct, and use it

? Piaget noted that reality is a dynamic system
of continuous change.
? Specifically, he argued that reality involves
transformations and states.
? Transformations refer to all manners of
changes that a thing or person can undergo.
? States refer to the conditions or the
appearances in which things or persons can be
found between transformations.
4. Cont¡
? Assimilation is how humans perceive and
adapt to new information.
? Accommodation is the process of taking new
information in one's environment and altering
pre-existing schemas in order to fit in the new
informa
? Piaget proposed four stages of cognitive
development: the sensorimotor,
preoperational, concrete operational and
formal operational period.

The sensorimotor stage is the first of the
four stages in cognitive development which
"extends from birth to the acquisition of

Pre-operational stage. It starts when the
child begins to learn to speak at age two and
lasts up until the age of seven.

? Egocentrism
? lack of conservation
6. Cont¡
The concrete operational stage occurs
between the ages of 7 and 11 (preadolescence) years.
? hypothetical thinking is not yet developed
? conservation
? Inductive reasoning
? deductive reasoning
The final stage is known as the formal
operational stage (adolescence and into adulthood,
roughly ages 11 to approximately 15¨C20).

? Abstract thought
? Metacognition
