What would be the estimated age of the infant? Mommy Linda is playing with her infant, who is sitting securely alone on the floor of the clinic. The mother hides a toy behind her back and the infant looks for it.
Answer: (D) 10 months
Rationale: A 10 month old infant can sit alone
and understands object permanence, so he
would look for the hidden toy. At age 4 to 6 months, infants cant sit securely alone. At age
8 months, infants can sit securely alone but
cannot understand the permanence of objects.
