Crit. #1--Piaget probably underestimated the abilities of children

 

 

 


Criticism #2:

Is development best thought of in "stages?"

 

 


Egocentrism again

If asked to show mommy a picture, 2 - 3 year olds will turn the picture the correct way.

 

 


Conservation again

When children play a game where the "number" determines the winner, they are not thrown off by changes in the spacing.

 

 


So, was Piaget wrong?

 

 


What about all those other developmental theories?
