| Abstract: | It has been claimed that the nearly logarithmic form of some category scales supports Fechner's law. However, by assuming that the concepts of similarity and difference are quantitatively complementary, it is possible to deduce the category scale equation from the similarity function. Thus, the category scale equation cannot be taken as evidence of the validity of Fechner's law. |
