Though it is well known that solving mental tasks elicits tonic increases in cardiovascular activity, a good theory explaining the specificity of this effect is lacking. It is also unclear why different kinds of mental tasks elicit different response patterns. The aim of the experiment was to compare cardiovascular response patterns during three tasks matched for their duration (8 min) and probability of success (.5): a simple RT task and two numeral tasks. One of them (a RUN task) involved program running (performing basic arithmetical operations), the other (an EDIT task) required searching for a problem solution. Seven cardiovascular variables, measured by a Portapres monitor, were analyzed. The analysis showed, among other findings, that the tonic increase in blood pressure and heart rate was greater during the RUN task than during the RT task. On the other hand, the EDIT task and the RT task produced almost identical response patterns.
虽然众所周知，解决心理任务会引起心血管活动的紧张性增加，但缺乏能够很好解释这种效应特异性的理论。也不清楚为什么不同类型的心理任务会引起不同的反应模式。实验的目的是比较三种任务的心血管反应模式，这三种任务的持续时间（8 分钟）和成功率（.5）相匹配：一个简单的 RT 任务和两个数字任务。其中一个（RUN 任务）涉及程序运行（执行基本的算术运算），另一个（EDIT 任务）需要寻找问题的解决方案。通过 Portapres 监测仪测量了七个心血管变量。分析结果表明，在 RUN 任务中，血压和心率的紧张性增加比在 RT 任务中更大。另一方面，EDIT 任务和 RT 任务产生的反应模式几乎相同。
