It is not surprising that children imitate intentional, useful actions. However, children also choose to imitate in more surprising ways. Which kind of action would a child likely imitate? Accidental (e.g. knocking something over unintentionally), constrained (e.g. using a foot to open a door after they saw someone with hands full do this), unnecessary or irrelevant (e.g. tapping the top of a box before opening the door containing a prize).
