Neural mirroring has been suggested as a mechanism underlying this behavioral phenomenon. Suppression of electroencephalogram (EEG) power in the mu frequency band, an index of motor activation, typically reflects neural mirroring. However, contradictory findings exist regarding the association between mu suppression and motor familiarity in infant EEG studies. In this study, we investigated the neural underpinnings reflecting the role of familiarity in action perception. We measured neural processing of familiar (grasp) and novel (tool-use) actions in 9- and 12-month-old infants. Specifically, we measured infants' distinct motor/visual activity and explored functional connectivity associated with these proceJournal of experimental child psychologyNeural correlates of familiar and unfamiliar action in infancy.PMC9086142P01 HD064653Fox NADebnath RMeyer MWoodward AChung HfalseNeural correlates of familiar and unfamiliar action in infancy.Behavioral evidence shows that experience with an action shapes action perception.
