| Research Abstract |
We carried the visual discrimination or judgment experiments for orientation, numerosity, and multi-dimensional categories in order to study the expertise process of human visual cognition and to make criteria of the expertise. Based on data of these experiments, we showed that following factors can be used as the index of the expertise : stabilized amplitude of internal noise in cognitive process, deviation of the Weber fraction and the PSE, reduction of stimulus dimensions, and the categorical percept.
