(A) Stimulus sample of face judgment task: female, facial expression ranges from 100% happy /0% fearful to 0% happy /100% fearful, all morphs were created by customized scripts in MATLAB R2017a (MathWorks Inc., Natick, MA, USA). (B) Emotional face judgment task. A face was presented after a fixation cross, and then participants were required to judge whether the emotion conveyed by the face is "fearful" or "happy" within 1.5 s. (C) Emotional oddball task. A picture was presented after a fixation cross, and participants were required to answer whether it is a standard stimulus or an oddball stimulus within 1.5 s immediately. (D) Overview of experimental condition and schematic representation of one full session. Note that the task order was the same on two experiment days and counterbalanced between the participants.
