This behavior is characteristic of the sensorimotor stage, which lasts from birth to approximately 2 years old. During this stage, infants develop object permanence, which is the realization that an object exists even when it is out of sight. Ian's behavior suggests that he has not yet developed object permanence, which is typical for an infant in the sensorimotor stage.
