Deferred imitation is a psychological learning mechanism that involves a child observing an action and then repeating it later:
Definition
Deferred imitation is the ability to reproduce an action or sequence of actions after a delay.
Process
A child observes an action, usually from an adult, and then repeats it after a period of time.
Purpose
Deferred imitation is a common way to assess a child's memory abilities.
Developmental stages
Developmental psychologist Jean Piaget theorized that infants develop deferred imitation between 16 and 24 months.
Explanation
Piaget believed that infants develop the ability to encode an internal representation of an object or action as their mental representation matures. This allows them to imitate after a delay, instead of relying on an external model.
