title: Effects of smoking, distraction, and gender on pain perception.
abstract: Whereas research on the antinociceptive effects of cigarette smoking has produced inconsistent findings, certain aspects of attentional processing repeatedly have been found to have an impact on pain perception. In an effort to delineate the relation between smoking and pain, the present study tested the attentional mediation model of smoking in pain perception. The authors hypothesized that by narrowing attentional focus, smoking in the presence of a distractor would facilitate distraction from painful stimuli, producing the most pronounced antinociceptive effect, compared with smoking or distraction alone. On the basis of previous findings of gender differences in pain, the authors hypothesized that the effects would vary by gender. The authors used the cold pressor test to assess pain threshold and tolerance in 76 smokers. A 2 (smoking/not smoking) x 2 (distraction/no distraction) x 2 (male/female) between-subjects analysis of variance (ANOVA) yielded Distraction x Gender interactions for pain threshold and pain tolerance. Pain sensitivity was lower in the distraction condition for men only. Whereas the results did not support the attentional mediation model of smoking in pain perception, they highlight the importance of distraction and gender differences in experimental pain.
