本研究的目的是评估冲动性与基线心血管水平和反应性在两个实验室压力在女性和男性的年轻成年人。对101名大学生在静息状态、反应时和言语任务中的心率（HR）、血压（BP）和心率变异性（HRV）进行了测量。冲动使用Barratt冲动量表-11和Block的自我控制量表进行测量。男性和女性的反应相似，这两个实验室的任务，也没有不同的冲动规模。对于男性，更高的冲动分数与较高的收缩压水平在休息，但降低收缩压和HR反应性在准备的讲话任务;女性表现出没有关系的休息心血管水平与冲动，但更冲动的女性确实表现出降低HR反应在讲话准备。冲动性和心率变异性水平或反应性之间没有显着的关系。据推测，任务涉及一定程度的规划可能是重要的冲动和心血管反应之间的关系，特别是在男性。(c)2009 Elsevier B.

The present study was conducted to assess the relationships of impulsivity with both baseline cardiovascular levels and reactivity during two laboratory stressors in both female and male young adults. Heart rate (HR), blood pressure (BP), and heart rate variability (HRV) were measured at rest and during a reaction time and speech task in one hundred and one undergraduate students. Impulsivity was measured using the Barratt Impulsiveness Scale-11 and Block's Ego-Undercontrol Scale. Males and females responded similarly to both laboratory tasks and also did not differ on the impulsivity scales. For males, higher scores on impulsivity were associated with higher systolic BP levels at rest but decreased systolic BP and HR reactivity during the preparation of the speech task; females showed no relationships of resting cardiovascular levels with impulsivity, but more impulsive females did show decreased HR response during speech preparation. No significant relationships were found between impulsivity and either HRV levels or reactivity. It is speculated that tasks involving a degree of planning may be important to find relationships between impulsivity and cardiovascular reactivity, especially in males. (c) 2009 Elsevier B.V.
