In general, when it comes to infants cognitive development, it appears that Piaget :

  • A.overestimated infants
  • B.underestimated infants
  • C.was more accurate about cognitive development
  • D.overestimated the role of culture

Answer: B

Piaget appears to have underestimated infants.

Later research using methods that do not depend on infants' motor skills, such as looking-time and violation-of-expectation studies by Renee Baillargeon and others, found that infants show signs of object permanence, numerical sensitivity and understanding of physical events months earlier than Piaget's search tasks suggested. Piaget's tasks required infants to reach and search, which they cannot do well until later.

So he did not overestimate infants, and his timetable for infancy was not more accurate. Overestimating culture is not the criticism; Piaget was criticised rather for paying too little attention to cultural and social influences.
