Cardiovascular measures are used in applied settings to assess mental load. It is neither desirable nor possible to adapt the working situation to the needs of the experimenter, as can be done in the laboratory; the purpose of this paper is to discuss how invested effort, mental efficiency, and changes in cardiovascular state can be measured in applied settings, including non-stationary ones. This paper discusses the theoretical background of fluctuations in heart rate and respiration and the application of existing methods in laboratory and normal working situations. Data acquisition and analysis methods are then presented, particularly the problems of artifact detection and correction and variability indices in spectral bands in relation to the reliability of these measures. In the last section the interpretation of data acquired in environments and the specific problems inherent in such situations are discussed.
心血管测量方法在实际应用场景中用于评估心理负荷。与在实验室中不同,使工作环境适应实验者的需求既不可行也不理想;本文的目的是讨论如何在包括非稳定环境在内的实际应用场景中测量投入的努力、心理效率和心血管状态的变化。本文讨论了心率和呼吸波动的理论背景以及现有方法在实验室和正常工作场景中的应用。接着介绍了数据采集和分析方法,特别是伪迹检测与校正问题以及与这些测量可靠性相关的频谱带变异性指标。在最后一部分,讨论了在实际环境中采集的数据的解读以及此类场景中固有的具体问题。
