Cardiovascular emotional dampening is the term used to describe the inverse relationship between resting blood pressure and emotional responsivity which extends from normotensive to hypertensive ranges. Little is known about its underlying physiological mechanisms, but it is thought to involve some disruption in emotion processing. One area that has yet to be explored in the literature is the relationship between emotional dampening and frontal asymmetry, a psychophysiological indicator for motivational direction and emotional valence bias. The present study explored that relationship using data from a sample of 48 healthy college students. Measures of baseline resting blood pressure and frontal cortical activity were recorded, after which participants completed a series of emotion-related tasks. Results revealed a significant relationship between resting systolic blood pressure and left frontal activity. Likewise, left frontal activity was associated with neutral appraisal of emotionally valenced stimuli within the tasks. The findings from the present study yield support for a link between emotional dampening and left frontal activity. Implications are discussed.
