The experimenter determined the energy intensity corresponding to an average score of 7 points among the participants. Subsequently, each participant received a fixed-intensity laser stimulation approximately every 20 seconds, for a total of 16 trials, during which they provided pain ratings ranging from 0 to 10. A rating of 0 indicated no sensation, 4 denoted the onset of pain perception, 6 represented moderate pain, 8 indicated severe pain, and 10 signified intolerable pain.\n2.Participant task information(description of the experiment): \nParticipants received laser stimulation and used a computer mouse to click on the appropriate position on the screen, corresponding to a scale of 0 to 10.\n3.Participant instructions(as exact as possible):\nParticipants were instructed to concentrate on the laser stimuli, maintain open eyes, and fixate their gaze on a cross displayed on the screen before them.  Following the presentation of each laser stimulus, there was a pause of 3�C5 seconds.  Subsequently, participants orally rated the intensity of pain within a time window of 3�C5 seconds for each rating.  The subsequent trial commenced randomly within 1�C3 seconds after the ratings were provided.\n4.References and links:\nLu X, Thompson WF, Zhang L, Hu L.
