Acupuncture analgesia and radiant-heat pain: a signal-detection analysis.

Responses to radiant-heat stimulation to the back of the hand were obtained during baseline conditions and during acupuncture sessions. Signal-detection methodology and analysis were used to determine whether acupuncture affects d' (changes physiologic processes) relative to pain report. A binary rather than a rating-scale procedure was used to obtain more accurate measures of sensitivity. Results indicated that acupuncture decreased sensitivity only at intensity levels that were never described as painful.

Signal detection theory and the psychophysics of pain: an introduction and review.

A brief explanation of signal detection theory is presented, followed by a review of the literature in which differences in pain report were analyzed to determine if changes were in sensitivity (physiological processes) or in response bias (a subject's willingness to report that a signal occurred). Three kinds of studies are reviewed: modification, procedural, and comparative and normative. The advantages of using a signal detection approach in pain research are emphasized. It is concluded that experimenters applying signal detection analysis to pain research should give greater consideration to methodological procedures and be cognizant of all possibilities for shifts in sensitivity (d)'.
