The underlying constructs for an experimental battery (EB) consisting of artistic judgment tests--the Design Judgment Test (DJT), the Visual Designs Test (VDT), Proportion Appraisal (PA), and the Visual Aesthetic Sensitivity Test--were studied. Scores for 1,686 clients of the Johnson O'Connor Research Foundation's aptitude-testing service were correlated with 24 tests in the Foundation standard battery, an artistic background questionnaire (ABQ), and the Career Occupational Preference System interest scales. In addition, the tests were analyzed for their relationships with examinees' college major and years of education, and measures of laterality. The results indicate that the EB was largely independent of the aptitudes tested by the Foundation battery. A regression of the EB on the standard battery showed little common variance. However, modest correlations between the artistic judgment tests and several aptitudes were found. Data from the ABQ indicated that the DJT, the VDT simplicity scale, and the PA consensus scale were significantly related to participation in art-related activities. These measures also showed significant relationships with interest in art occupations. Artistic judgment scores of examinees who majored in art differed significantly from those of non-art majors. Little relationship between scores on the EB and years of education was found. The DJT, VDT simplicity scale, and PA consensus scale show broad associations with art criteria, are largely independent of education, and are not highly related to other aptitudes. Thirteen data tables, 5 figures, and an 88-item list of references are included. Appendix A provides the coding system for the ABQ, and Appendix B presents correlations not corrected for attenuation.
