Four experiments are reported in which the direct psychophysical scaling methods of magnitude estimation, category judgment, and cross-modality matching were mixed in the same series of trials, both with a single stimulus modality and in a mixed-modality situation. The mixed-method scaling situation gave results consistent with those obtained when methods are used alone, and it has several advantages. Interactions between the methods were consistent with the idea that judgments made under all three are mediated by a primitive process of categorization that is influenced by heuristics used to achieve a single category identity for each stimulus.
本文报告了四项实验，在这些实验中，大小估计、类别判断和跨通道匹配等直接心理物理学标度方法在同一系列试验中混合使用，既有单一刺激模态的情况，也有混合模态的情况。混合方法标度情况得到的结果与单独使用这些方法时一致，并且有几个优点。这些方法之间的相互作用与以下观点一致：在所有这三种方法下做出的判断是由一个原始分类过程介导的，该过程受到用于为每个刺激实现单一类别身份的启发式方法的影响。
