According to Piaget, deferred imitation, which involves the ability to imitate a behavior after a delay, requires the use of symbolic functioning. This means that the child must be able to represent the behavior in their mind as a symbol (such as a mental image or word) and then retrieve that symbol later to imitate the behavior. This ability typically emerges in the sensorimotor stage around 18-24 months of age.
