研究人员对24名中国男性和24名白人男性的血压、心率以及面部和手指血流的变化进行了监测，同时让他们描述激怒事件，并大声快速或轻声缓慢地朗读中性材料。大声、快速地描述这些事件会提高愤怒等级，增强血管收缩，但不会提高血压或心率;然而，愤怒会在柔和时提高血压。缓慢的演讲面部血流量增加愤怒的表达，无论讲话风格，但减少时，中性材料读出。研究结果表明，面部血流的增加降低了愤怒表达时的外周血管阻力。并且压力反射减弱心率和血压的增加。种族背景没有影响主观报告或生理反应，可能是因为该程序没有充分利用文化禁忌。
Blood pressure, heart rate, and changes in facial and finger blood flow were monitored in 24 male Chinese and 24 male Caucasians while they described anger-provoking incidents and read out neutral material, either loudly and rapidly or softly and slowly. Describing the incidents loudly and rapidly heightened anger ratings and enhanced digital vasoconstriction but not blood pressure or heart rate; however, anger enhanced blood pressure during soft. slow speech. Facial blood flow increased during anger expression, irrespective of speech style, but decreased when neutral material was read out. The findings suggest that an increase in facial blood flow reduces peripheral vascular resistance during anger expression. and that baroreflexes attenuate increases in heart rate and blood pressure. Racial background did not influence subjective reports or physiological responses, possibly because the procedure did not draw strongly enough on cultural taboos.
