About this trial

During the fear rating task, 70 participants viewed a 600-second horror movie while continuously rating their subjective fear intensity (0-100 scale) every 0.51 seconds (1,170 total ratings). Functional near-infrared spectroscopy (fNIRS) data were simultaneously recorded using the NIRSIT LITE system to monitor cortical hemodynamic responses.
