This study was concerned with the development and testing of an instrument to measure levels of aesthetic judgement making. The review of evaluation methods for aesthetic judgement resulted in a two-part instrument. The review of related literature demonstrated that the majority of instruments for aesthetic judgment employed a naive to sophisticated judgment comparison to determine levels of aesthetic sensitivity. The inadequacy of a score reporting only the degree of agreement between the subject's choice and the choice of a panel of experts without indicating the source agreement was discussed. Content analysis of aesthetic responses used in research studies by Wilson and Morris were presented as an alternative means for determining aesthetic criteria. Part one required the subject to select the better of two art works and to state the reasons for the choice. Part two, a self-scoring component, consisted of the Wilson categories presented as typical statements containing the primary criterion for the category. The subject was instructed to select the statements that were closest in meaning to his initial response.
