The social context in which pain is reported has been found to modulate pain. Specifically, male participants reporting pain to female observers report significantly lower pain levels compared to male participants reporting to male observers. Female participants seem less affected by social context. This is a methodological problem in the study of pain and has consequences in the development of new drugs, and for pain research in general.
The present study has two aims: To investigate whether social context affects also the placebo response to pain, i.e. the reduced pain often observed after administration of a an inert substance the participants believes to be a painkiller. It is hypothesized that placebo analgesia will be larger in males reporting pain to females. Secondly, heart rate variability and skin conductance, measures of parasympathetic and sympathetic activity, will be recorded, to investigate if social context affects not only pain report, but also pain response.
