Decentration

toc

Definition:
From the book: Decentration is a level of thinking that takes into account many differant variables. Piaget's definition: The ability to move away from one system of classification to another one as appropriate. Decentration is one of Piaget's Key Ideas, along with: Adaptation, Assimilation, Accomodation, Classification, Class inclusion, Conservation, Ego centrism, Operation, Schema/Scheme, and Stage. HGD, Chapter 9, p. 223

Examples:
The school-aged child can see that a clay ball rolled into a sausage shape is wider than it was before, but also shorter. Decentration leads him to believe that the reduced height of the sausage shape compensates for it's increased width and therefor has the same amount of clay.
