We describe a theoretical framework for the measurement of the intensity of emotional experiences and summarize findings of a series of studies that implemented this framework. Our approach is based on a realist view of quantities and combines the modern psychometric (i.e., latent-variable) view of measurement with a deductive order of inquiry for testing measurement axioms. At the core of the method are nonmetric probabilistic difference scaling methods, a class of indirect scaling methods based on ordinal judgments of intensity differences. Originally developed to scale sensations and preferences, these scaling methods are also well-suited for measuring emotion intensity, particularly in basic research. They are easy to perform and provide scale values of emotion intensity that are much more precise than the typically used, quality-intensity emotion rating scales. Furthermore, the scale values appear to fulfill central measurement-theoretical axioms necessary for interval-level measurement. Because of these properties, difference scaling methods allow precise tests of emotion theories on the individual subject level.
我们描述了一个用于测量情感体验强度的理论框架，并总结了一系列实施该框架的研究结果。我们的方法基于对量的现实主义观点，并将现代心理测量（即潜变量）测量观点与用于测试测量公理的演绎探究顺序相结合。该方法的核心是非度量概率差异缩放方法，这是一类基于强度差异的顺序判断的间接缩放方法。这些缩放方法最初是为了对感觉和偏好进行缩放而开发的，也非常适合测量情感强度，特别是在基础研究中。它们易于执行，并提供比通常使用的质量强度情感评级量表精确得多的情感强度量表值。此外，量表值似乎满足区间水平测量所需的核心测量理论公理。由于这些特性，差异缩放方法允许在个体受试者层面上对情感理论进行精确测试。
