Research Abstract

In color and sound perception, participants seem to perceive stimuli in categories, and this phenomenon is called categorical perception. In this study, we developed a psychometric method to investigate whether the perception of rhythm patterns is categorical perception. This method is an extension of the constant method of stimuli, which is widely used to examine the subjective magnitude of a stimulus. Our method succeeded in improving some of the shortcomings of the constant method of stimuli. On the other hand, while the ability to examine categoricity was confirmed to be effective in simulations, it was found to be difficult to obtain significant results with a realistic number of experimental participants.
