Although the joint measurement of heart rate (HR) and T-wave amplitude (TWA) in experiments manipulating psychological processes is a sound and fruitful approach, Penzien Hursey, Kotses and Beazel's (1982) interpretation of their results may be questioned on two grounds: (a) Wether the process being manipulated between their groups was really the degree of stress; and (b) whether the degree of threat or aversiveness is really indexed more reliably by HR changes than by changes in TWA. This note questions these two assumptions, and also offers an alternative vagal interpretation of the Penzien et al. (1982) results.
尽管在操纵心理过程的实验中同时测量心率（HR）和T波振幅（TWA）是一种合理且富有成效的方法，但彭齐恩·赫西、科茨斯和贝泽尔（1982）对其结果的解释可能在两个方面受到质疑：（a）他们两组之间所操纵的过程是否真的是压力程度；（b）与TWA的变化相比，心率变化是否真的能更可靠地反映威胁或厌恶程度。本说明对这两个假设提出质疑，并对彭齐恩等人（1982）的结果给出了另一种基于迷走神经的解释。
