Scanner paradigm. Subjects viewed a cue screen reminding them which targets they were about to be see (4 s), followed by a video (14 s) showing the face of the target then zooming to the target's right hand as it received either an injection from a syringe (pain) or a touch from a q-tip (control). Following this condition, subjects were asked to rate how much they liked the people they just saw (5 s). Each of these sequences was followed by a 12 s rest. Each different screen was separated by a jittered fixation screen (1–2 s).
