摘要: Although startle and cardiovascular reactivity have been studied extensively, little is known about their relationship. In the present study, we examined responses affective modulation in 112 normotensive individuals varying self-reported fearfulness parental health history. An initial intense noise burst elicited a phasic cardiac acceleration that was larger for fearful individuals. Startle blink were during aversive than pleasant relaxing imagery but did not differ with fear group. Cognitive challenge tasks heart rate blood pressure increases unrelated to or However, greater potentiation by predicted pressor cognitive challenge, especially among men. The observed relationship between suggests common mechanism modulation.
