E-book Automatic Imitation
In this chapter, we present a range of techniques for measuring the speed, accuracy, and extent of imitation of others’ movements. In general, we define movement imi-tation as the production of a configural body movement that matches the movement performed by another. This definition comprises two components which are of par-ticular importance when deciding whether a given technique can be said to be mea-suring imitation. The first is the focus on configural body movements. This states that it is the configuration of body parts with respect to other body parts that are of importance in deciding whether a response is imitative (cf. Heyes, 2021). The emphasis on body part configuration is important because it allows us to distinguish imitation from other social learning processes such as stimulus enhancement (where watching another’s action focuses the observer’s attention on a particular body part, increasing the likelihood to engage in movements with this body part) or effector matching (where the observer performs an action using the same effector—hand, foot, etc.—as that used by the actor; see Whiten et al., 2004, for further definitions of social learning). For example, when attempting to imitate a movement such as a swimming stroke, the observer must produce a movement that not only uses the same effectors as those used by the actor (e.g. the arm and hand) but also moves those effectors in the same way with respect to the rest of the body. Moving the arm and hand in a different configuration would be classified as effector matching rather han successful imitation: the observer has identified which part of the body to move, but not how to move it.The second part of the definition focuses on the matching nature of the relation-ship between the actor’s movements and the observer’s movements. It is not enough for the observer to perform a configural body movement in response to the actor’s movements: the observer’s body movement must match that of the actor.
