Experimental paradigm. Panel (A,B) reported an example of congruent (A) and Incongruent (B) trials (A). The trial started with a fixation cross (500 ms duration), followed by a cue (diverging arrows, 350 ms duration) that instructed the subject about the movement to perform. After the cue, the video stimulus was presented and the subject started the movement after the end of the video. In this case a mouth-opening gesture was followed by a lip-stretching movement. (B) The sequence is the same of that reported in (A). However, in this case, the requested movement was incongruent respect to the visual stimuli.
