Abstract: | A procedure, based on the method of adjustment, for estimating perceptual noise is presented. The resulting estimates can be used to obtain a better understanding of categorization behavior, to answer questions about the distributional form of perceptual noise, and to test for perceptual independence. All three applications are demonstrated in a categorization task involving two categories. |
