Data for a single subject from a categorical perception experiment. The upper panel gives labeling or identification data for each step on a [b]/[g] place-of-articulation continuum. The lower graph gives this subject’s ABX discrimination data (filled circles) for the same stimuli with one step difference between pairs, as well as the predicted discrimination performance (open circles). Discrimination accuracy is high at category boundaries and low within categories, as predicted. (Reprinted with permission from Ref. 9 Copyright 1957 American Psychological Association.)
