The best cue that even infants use to determine whether an object is animate or not is self-propelled motion. Infants as young as 3 months old show a preference for visually attending to and tracking self-propelled objects, indicating that they have an early understanding of animate versus inanimate objects. This ability develops further as they grow older and strengthen their understanding of object permanence and cause and effect relationships.
