Person perception and autonomic nervous system response: the costs and benefits of possessing a high social status

This research was designed to investigate the relationship between sympathetic and parasympathetic autonomic nervous system (ANS) responses to the perception of social targets varying in social status. Participants varying in subjective financial status were presented with faces assigned with either a low, average, or high financial status. Electrocardiographic and impedance cardiography signals were recorded and measures of sympathetic (pre-ejection period; PEP) and parasympathetic (high frequency heart rate variability; HF HRV) cardiac control were derived. These measures associated with the presentation of each face condition were examined in relation to the subjective status of the perceivers. Participants with high subjective financial status showed reduced sympathetic activity when viewing low- and medium-status targets as compared to high-status targets, and lower parasympathetic response when viewing high- and medium-status targets relative to low-status targets.
