Three experiments examined category creation with no feedback and minimal feedback by using modeling to determine number of dimensions subjects attended to. In the first experiment, subjects were shown a series of two-dimensional objects with no training and no feedback and asked to categorize the stimuli. Subjects in experiment 1 mostly attended to one dimension. In the second experiment, subjects shown similar two-dimensional stimuli but were given minimal feedback. Significantly more subjects in experiment 2 attended to both dimensions. In the third experiment, subjects were trained on three related two-dimensional categories and then asked to categorize four. Performance in experiment 3 was similar to that of experiment 1, where subjects mainly attended to 1 dimension. These findings indicate that a more natural feedback structure would help subjects create categories that resemble those used in everyday life.
