University of Georgia, Athens. ABSTRACT. Visual art is a complex stimulus. Drawing on extant theory that the interplay. of affect and cognition evoked by a stimulus drives evaluations, we develop. a generalizable model for the perception and evaluation of visual art. In. three stages, we develop scaled measurements for the affective and cognitive. components involved in the perception of visual art and present a structural. equation model that integrates these components in art evaluation. The nature of art has been a topic of philosophical interest since the days of the. ancient Greeks. Yet the experience of art, and consequently the perception and. evaluation of art, seemsparticularly challenging to comprehend within a scientific. framework.
