Illustration of the experimental procedure. A trial begins with a parallel display of four faces. A gray dot appears on one of the faces, between 3100 and 4500 ms after the parallel display onset, and participants are asked to report whether it appeared on the right or left side of the screen. Afterwards, a blank screen is presented followed by a single face. Between 2100 and 2700 ms after the single display onset, a gray dot appears on the face and participants are required to report again on which side of the screen the dot apeared. A personally familiar face could be presented in the parallel display, in the single display, in both displays or in none of them
