Piaget Suggested That Children Do Not Develop Object Permanence Until

Multiple Choice

Piaget suggested that children do not develop object permanence until between eight and 12 months of age. The research of Renee Baillargeon has found that this skill may develop much earlier. What was the difference that allowed Baillargeon to find such an earlier development of object permanence?

A) Baillargeon substituted monkey infants for human infants, and generalised her findings from the earlier development of object permanence in the monkey infants.
B) Baillargeon removed a parent from the room so that the child could stop using the parent as a "reference tool" for finding the object on their own.
C) Baillargeon added the element of "emotional connection" by using objects for which the children she studied had a particular affinity.
D) Baillargeon eliminated the need for a child to have the motor skills necessary to display object permanence and focused instead on the patterns of their gazes.
