Abstract Details

2009, Master of Science (MS), Ohio University, Psychology (Arts and Sciences).
Hypoalgesia is common in persons with and at risk for hypertension (Ghione, 1996; France, 1999) and may result from dampened affective responses to painful stimuli (Wilkinson & France, 2009; Jorgensen et al., 1996). Generally, pleasant affective stimuli decrease pain, whereas unpleasant affective stimuli increase pain (Rhudy et al., 2005). In the current study, it was hypothesized that the buffering effect of positive affect and the exacerbating effect of negative affect on pain would be less for those at increased risk for developing hypertension. Participants (N=117) were stimulated at 120% of their nociceptive flexion reflex (NFR) threshold while viewing pleasant, unpleasant, and neutral images. Electromyographic response magnitudes, pain ratings, valence ratings, and arousal ratings were obtained. The hypothesis was not supported, possibly because the valence and arousal ratings showed little variability as a function of hypertension risk. It appears that dampened affect is not the mechanism of hypoalgesia in those at risk for hypertension.
