An example of the experimental procedure of dot-probe paradigm. A cue consisted of two pictures. In cueing trials, one of the pictures was a painful/emotional picture, while the other one was a nonpainful/neutral picture. In non-cueing trials, both pictures were nonpainful/neutral pictures. A probe was presented immediately after the disappearance of the cue, and persisted until the participant made a response within 5000 ms. Participants were asked to judge the orientation of the probes.
