A, Each trial started with a fixation cross presented for a random duration of 1000–2000 ms (1000, 1200, 1400, 1600, 1800, and 2000 ms). After the fixation cross, the face of a stranger was presented. The participants then replied whether they detected hostility in the face by pressing the button held in the right or left hand. The next trial was started immediately after pressing the button. A total of 148 pictures were presented in random order, and the total time of the task was approximately 7–10 min. All faces showed direct gaze and were presented on a black background. We defined the periods of interest as 200-ms windows starting 100 ms after onset of stimulus. B, Representative facial pictures of four different facial expressions (happiness, anger, ambiguity, and neutrality). ERS, event-related synchronisation.
