Example of the emotional Go/No-Go task used in the study. Images showing facial expressions appear sequentially on the screen. The user should respond quickly to emotional faces (either happy or sad foil images/Go; 80% of trials) and withhold from responding to rare neutral faces (target stimuli/No-Go; 20% of trials). Images were taken from the KDEF image set. Written consent for publication of human identity revealing images was obtained from the creators of the KDEF set. The task included 100 trials.
