This work explores if it is possible to operationalize aesthetic concepts. In the two studies undertaken, different compositions of design elements, such as color and shapes, were used to test whether they have the capability of contributing to the perception of a particular aesthetic concept. In each study. 29 participants (both students and professionals) took part. Participants evaluated a series of abstract pictures and rated how mysterious, complex, familiar, and interesting they thought the pictures were. In the first study, each picture was constructed by using 9, 18, or 27 shapes. The shapes u.sed were either circles, squares, unfamiliar shapes, or a mixture of all three. Additionally, the shapes used were either partially hidden or fully visible. In the second study, the shapes were also presented using two different colors and shades. The results were analyzed using a repeated measures ANOVA, and It was found that certain design elements indeed have the capacity to impact upon the way in which stimuli are perceived. However, the input of particular design elements lo the way in which pictures are perceived is complicated in that they are often indirect contributions through interactions with other design elements.
