It has been hypothesized by many researchers that aesthetic appreciation is not only based on stimulus properties or individual differences, but rather that it is the compatibility between stimulus and person characteristics that determines aesthetic appreciation. In support of this, recent evidence suggests that if an individual can handle the complexity of an artwork, this artwork is preferred over other less complex pieces. Based on this preliminary evidence, we hypothesize that aesthetic appreciation depends on the compatibility or the match between an individual’s working memory capacity and the visual complexity of a stimulus. In addition, we expect preferences for complexity to depend on the individual’s working memory load within a specific context. In the current study, 268 participants rated subsets of a parametrically controlled set of 1611 stimuli varying both qualitatively and quantitatively on diverse objective order and complexity dimensions (created using the Order and Complexity Toolbox for Aesthetics; OCTA). Based on these ratings, we categorized the stimuli into a 3x3 (low, moderate, high) order and complexity grid. In a follow-up study, a selection of the stimuli will be presented to participants in a dual-task format. The participants will have to perform a 2-alternative forced choice task in which they have to indicate their preferences for visual stimuli with or without working memory load. This study will allow us to examine how both individual and contextual differences in working memory capacity relate to the appreciation of order and complexity in a parametrically controlled stimulus set.
