This study aimed to investigate the effects of elevated blood pressure on the basic motivational systems of approach and avoidance to positively- and negatively-valenced stimuli. The results showed that individuals with high blood pressure were faster to respond to angry facial expressions and did not show any significant differences in response time to happy facial expressions.
Emotional dampening (blunted responses to affective stimuli or experiences) has been reported in individuals with clinical and subclinical levels of elevated blood pressure (BP). Our aim in the present study was to explore how the basic motivational systems of approach and avoidance to positively- and negatively-valenced stimuli are affected in elevated BP. High BP (n = 27) and Low BP (n = 29) participants completed an approach-avoidance task. In this task, participants pulled the joystick towards them when viewing a happy face (approach) and pushing it away when viewing an angry face (avoid) in the congruent condition, and reversed these action-to-emotion pairings in the incongruent condition. A mixed-design ANOVA revealed a significant main effect of condition, such that overall participants were faster across trials in the congruent than trials of the incongruent condition. There was also an emotion x BP interaction. Among the Low BP group, there were no RT differences to happy and angry expressions (across congruent and incongruent conditions) but those with High BP were quicker to respond to actions paired with angry than happy facial expressions (across conditions). Findings suggest that valence-specific motivational reactions are not dampened with an increase in BP, and are rather sensitized for the negative emotion of anger.
