Notes: Statistics were obtained by applying mixed‐design three‐way ANOVA with one between‐participant factor of Group (HPS or LPS group) and two within‐participant factors of Stimulation (painful vs. nonpainful stimulation) and Task (Pain Judgment vs. Hands Counting Task) on behavioral and neural responses during the empathy for pain tasks.
