Schematic representation of one trial of the task. (1) The virtual agent looks down at the beginning of the trial. The participant focuses on the eye region of the virtual agent. Then, the virtual agent either averts the gaze (2a) by looking up (No_JA) or engages in eye contact with the participant (JA, 2a). The virtual agent shifts his focus of attention to an object on the left (3a) or right (3a) and the participant follows his gaze. The virtual agent maintains a neutral expression until this point. After the participant's gaze has been detected in the object region, the virtual agent performs a facial expression of either disgust (4a) or happiness (4b) for 1000 ms after participant looked at expression.
