Experimental procedure. The robot (iCub) starts with its eyes closed for 2 s (A). Subsequently, it opens the eyes for 500 ms (without moving the head) (B). Then, iCub looks either down (no eye contact) or towards the participants’ eyes (eye contact) for 2.5 s (Experiment 1) or 1.5 s (Experiment 2) (C). After this, iCub moves its head laterally to gaze towards a potential target location (D). After 1 s (Experiment 1) or 500 ms (Experiment 2), the letter V or T appears randomly on one of the screens for 200 ms (E). The participant (not shown) identifies the target by pressing the mouse button (left or right) (F).
