The sequence of events in an experimental trial started with a white fixation cross lasting for 900 ms (image a), then a face looking forward appeared remaining on the screen for others 900 ms (image b), when it was superimposed by the same face looking to the left or to the right (image c), 200 ms later a white target letter (i.e., an “L” or a “T”) appeared either on the left or on the right of the face (image d). In this example, the avatar of the cueing face was a White man and the gaze was averted toward the position in which the target letter appeared. Stimuli are drawn to scale. The cueing-face is taken from the database created by Pavan et al. [15]
