Figure 1 Visual depiction of counter-balanced trials of words presented during the dot-probe task.
Notes: Sensory pain word (target, t) on left (l) side of screen followed by the dot (d) on the left side of the screen (left, congruent or “tldl”), sensory pain word on left side of screen followed by the dot on the right (r) side of the screen (left, incongruent or “tldr”), sensory pain word on right side of screen followed by the dot on the right side of the screen (right, congruent or “trdr”), and sensory pain word on right side of screen followed by the dot on the left side of the screen (right, incongruent or “trdl”).
