Individual differences in aesthetic judgments were investigated by comparing quantitative group and individual performance models of the judgment processes. Aesthetic judgments of beauty over novel, formal, graphic patterns were collected from 34 non-artist college students using a two-step ranking-rating procedure. Their judgment processes were individually modelled using Judgment Analysis. The participants showed noted individual differences. Certain features of the stimulus material, which were considered to contribute to the picture's beauty by one participant, were used in an opposing fashion by another. A group model was derived based on the average ratings of the patterns' beauty. It was concluded that the group model was not an adequate representation of the present data, whereas the data revealed systematic judgment processes at the individual subject level.
