Visual Complexity and Beauty Appreciation: Explaining the Divergence of Results

Abstract

Although a number of studies have verified Daniel Berlyne's (1971) predicted maximum preference for intermediately complex stimuli, others have found that preference increased or decreased in relation to complexity. The objective of the present work was to assess whether differences in the kinds of stimuli used in prior studies or in the way complexity was defined could explain this divergence. In the first phase a set of 120 stimuli varying in complexity, abstraction, and artistry was assembled. In the second phase 94 participants were asked to rate the beauty of the stimuli. In the final phase the same participants rated 60 of the stimuli on seven complexity dimensions. We failed to detect any meaningful influence of complexity on beauty ratings for any of the kinds of stimuli. However, our results suggest that there are three different forms of complexity that contribute to people's perception of visual complexity: one related with the amount and variety of elements, another related with the way those elements are organized, and asymmetry. We suggest that each of these types of complexity influences beauty ratings in different ways, and that the unresolved relation between complexity and beauty appreciation is mainly due to differences in the conception, manipulation, and measurement of visual complexity.
