Elevated resting blood pressure (BP) is associated with dampened responses to emotionally meaningful stimuli. This BP-associated emotional dampening may also influence threat appraisal and, hence, motivation to avoid risk. The present study was designed to determine if resting BP is associated with risky driving behavior assessed in a high fidelity driving simulator. Fifty-one healthy women (n = 20) and men (n = 31) rested for BP determinations both before and after a simulated driving scenario in a DriveSafety automotive simulator with six visual channels, single-axis motion, and functioning controls and instrumentation. Resting systolic (SBP) and diastolic (DBP) BPs were obtained systematically with a calibrated GE Dinamap Pro V100. Risky driving was assessed by speed relative to the posted speed limit, and a speed-adjusted time to collision index of tailgating. Regression analyses indicated that sex interacted with resting BP, with significant associations between BP and risk in women, but not men. For example, risky driving in women was associated with higher resting DBP (p = .006), with similar but less reliable effects for resting SBP (p = .058). These results provide some partial, preliminary support for the notion that BP-associated emotional dampening may reduce threat appraisal and thereby decrease motivation for risk avoidance, but these effects are confined to women in this simulated driving scenario. Interacting central nervous system (CNS) mechanisms controlling BP and emotional responsivity may mediate the relationship between BP and risk-taking behavior. Relative expression of this relationship in women and men may depend on multiple psychosocial and physiological mechanisms. The association of higher BP with increased risk-taking behaviors may have relevance to the early pathogenesis of essential hypertension., (Copyright © 2020 Elsevier B.V. All rights reserved.)
