Experimenter gender significantly interacted with subject gender on subjective pain intensity and arousal, but did not affect autonomic physiological responses to heat pain.
Several studies have shown that male subjects report lower pain intensity to female compared to male experimenters. The present experiment examined whether experimenter gender also modulated autonomic pain responses. Sixty-four students (32 females) participated in a 2 Subject gender x 2 Experimenter gender x 15 Pain Tests mixed design. Six experimenters, three females and three males collected data. Heat pain was +48 degrees C induced to the right volar forearm. Subjective measurements consisted of pain intensity, pain unpleasantness, stress, arousal and mood. Autonomic responses were heart rate variability and skin conductance levels. The results revealed significant interactions between experimenter gender and subject gender on pain intensity and arousal, but there were no interactions in the physiological data. In conclusion, the lower pain report in male subjects to female experimenters is not mediated by changes in autonomic parameters, and the effect of experimenter gender is probably due to psychosocial factors.
Aslaksen et al. (Wed,) reported a other. Female experimenter vs. Male experimenter was evaluated on Autonomic pain responses (heart rate variability and skin conductance levels) and subjective measurements. Experimenter gender significantly interacted with subject gender on subjective pain intensity and arousal, but did not affect autonomic physiological responses to heat pain.
