Note. Within-subject design with two blocks (represented along the x-axis): Each block contains 18 trials, presented in randomized order, and separated by a self-paced break. Y-axis breaks down the timing of the trials: Emotional Face (EF) = 350s, is paired simultaneously with Emotional Prosody (EP ~ 2s); SOA (stimulus onset asynchrony) = 1,650ms. Audiovisual presentation is followed by a two-alternative forced-choice (2AFC) task (time limit = 3s); inter-trial interval (ITI) = 2s. Max. block duration = 126s; max. testing phase (discounting the break) = 252s ~ 4.2 mins. KDEF images used in figure as examples are: “AF25HAS”, “AF20ANS”, “AM06NES”.
