The concept of stability has been developed in structural stabilty theory of mathematics. This concept plays an important role in characterizing the nature of a scientific law. Yoshino (1989a) introduced it into axiomatic measurement theory developed by mathematical psychologists, and analyzed some experimental data concerning psychophysical laws. The main objective of the present paper is to develop a concept of “degree of stability” for the further study of the nature of a scientific law, especially, a psychophysical law. Some experimental data on the Stevens' power law are analyzed from the standpoint of degree of stability. Finally, some possible experiments are suggested for the future development of this research.
