Researchers determined the energy intensity corresponding to an average rating of 7 from the participants.  Subsequently, each participant received 10 laser stimulations and was prompted to rate pain intensity (ranging from no sensation to the worst pain imaginable) and unpleasantness (ranging from no unpleasantness to the most unpleasant) on a numeric rating scale (NRS) from 0 to 10.  Participants indicated their chosen scores by clicking on the corresponding position on a screen, and scores were recorded, potentially including decimal values, to accommodate for precision in pain assessment.\n2.Participant task information(description of the experiment):\nParticipants were administered a laser stimulation and then provided scores by clicking on the corresponding position along the 0 to 10 axis using a mouse.\n3.Participant instructions(as exact as possible):\nParticipants were instructed to focus their attention on the laser stimulation, keep their eyes open, and fixate their gaze on a crosshair displayed on the screen. Following the presentation of each laser stimulation, there was a 5-second pause. Subsequently, participants assessed the intensity of pain. The subsequent trials commenced randomly 5 seconds after providing the rating.\n4.References and links:\nLu, X., Yao, X., Thompson, W. F., & Hu, L. (2021).
