Which is a commonly cited critique of Piagetian theory?

• A. It provides too detailed processes of change
• B. It underestimates infants and overestimates adolescents
• C. It accounts for excessive variability
• D. It overemphasizes social and cultural influences

Answer: (B)

A frequent critique of Piagetian theory is that it underestimates what infants can do and overestimates what adolescents can consistently achieve. Modern research shows infants display competencies earlier than Piaget credited them for—things like object permanence, basic numerical discrimination, and simple social understanding emerge earlier than the stage milestones would suggest. On the other end, Piaget’s view of adolescence as a reliable leap into formal operational, abstract thinking is not borne out in all contexts or cultures; many adolescents rely on concrete reasoning in everyday tasks, and not all reach or routinely use advanced forms of reasoning. This combination—undervaluing infants’ abilities while overpromising the consistency and universality of adolescent formal reasoning—explains why this critique is commonly cited.
