The relationships between experienced discrimination and temporal summation of pain (TS-Pain; panel A) and temporal summation of the nociceptive flexion reflex (TS-NFR; panel B). Discrimination did not impact TS-Pain (persons experiencing low, moderate, and high discrimination all showed similar pain summation), but TS-NFR was moderated by discrimination. Although persons experiencing low, moderate, and high discrimination all showed significant summation of NFR, higher discrimination was associated with greater TS-NFR (panel B).
