Criticisms of Piaget:
1. It is based on naturalistic observation not scientific experimentation. 2. Explanatory mechanisms like schemes, assimilation, disequilibrium etc. are unobservable and appear to be explanatory fictions. 3. The theory deals only with the “cognitive domain”.

4. The theory is not parsimonious since it uses mental events as key components in the theory. 5. Predictions about the time periods in which skills should be learned have frequently been incorrect. 6. Piaget underestimated the effect of environmental variables on the acquisition of cognitive abilities. 7. Piaget’s view that children construct their own knowledge violates determinism since children are made the cause of their own behavior. This is a version of free will. 8. The theory fails to incorporate a large body of scientific facts coming from the experimental analysis of behavior that are inconsistent with the theory.
