Describe a standard test that a developmentalist might use to determine whether an infant has attained object permanence. Why might the test not work? Use your answer to explain why some of Piaget's findings have been challenged by other researchers
What will be an ideal response?
Look for answers that describe a standard test (toy under blanket, dish behind furniture
or tester's back), and note factors that would influence success that Piaget did not
consider, such as the child's motivation to search and familiarity with the objects used.
Mention might also be made of memory, a factor Piaget does not discuss.
