Neural correlates of being imitated: an EEG study in preverbal infants.
A foundational aspect of early social-emotional development is the ability to detect and respond to the actions of others who are coordinating their behavior with that of the self. Behavioral work in this area has found that infants show particular preferences for adults who are imitating them rather than adults who are carrying out noncontingent or mismatching actions. Here, we explore the neural processes related to this tendency of infants to prefer others who act like the self. Electroencephalographic (EEG) signals were recorded from 14-month-old infants while they were observing actions that either matched or mismatched the action the infant had just executed. Desynchronization of the EEG mu rhythm was greater when infants observed an action that matched their own most recently executed action. This effect was strongest immediately prior to the culmination of the goal of the observed action, which is consistent with recent ideas about the predictive nature of brain responses during action observation.
