We propose that aesthetic pleasure is a function of the perceiver's processing dynamics: The more fluently perceivers can process an object, the more positive their aesthetic response. We review variables known to influence aesthetic judgments, such as figural goodness, figure-ground contrast, stimulus repetition, symmetry, and prototypicality, and
trace their effects to changes in processing fluency. Other variables that influence processing fluency, like visual or semantic priming, similarly increase judgments of aesthetic pleasure. Our proposal provides an integrative framework for the study of aesthetic pleasure and sheds light on the interplay between early preferences versus cultural influences on taste, preferences for both prototypical and abstracted forms, and the relation between beauty and truth. In contrast to theories that trace aesthetic pleasure to objective stimulus features per se, we propose that beauty is grounded in the processing experiences of the perceiver, which are in part a function of stimulus properties.What is beauty? What makes for a beautiful face, appealing painting, pleasing design, or charming scenery? This question has been debated for at least 2,500 years and has been given a wide variety of answers (Feagin, 1995;Tatarkiewicz, 1970). However, one can broadly distinguish three main positions. Many theorists, dating back at least to Plato, saw beauty as a property of an object that produces a pleasurable experience in any suitable perceiver (Tatarkiewicz, 1970). This objectivist view inspired many psychological attempts to identify the critical contributors to beauty. Among the identified features were balance and proportion (Arnheim, 1974; Birkhoff, 1933;Fechner, 1876;Gombrich, 1995), symmetry (Arnheim, 1974; Birkhoff, 1933;Gombrich, 1984;Humphrey, 1997), informational content and complexity (Berlyne, 1971(Berlyne, , 1974Eysenck, 1941;Garner, 1974), as well as contrast and clarity (Gombrich, 1984(Gombrich, , 1995 St. Thomas of Aquinas, see Maritain, 1966;Solso, 1997). The objectivist view of beauty was so dominant in the 16th century that artists introduced pattern books, offering pictorial elements that artists could copy and combine with each other to create beauty (see Gombrich, 1995).Other theorists, dating back at least to the Sophists, proposed that anything could be beautiful if it pleases the senses (Tatarkiewicz, 1970). From this perspective, beauty is a function of idiosyncratic qualities of the perceiver and all efforts to identify the laws of beauty are futile. This subjectivist view, reflected in expressions like "beauty is in the eye of the beholder" or "de gustibus non est disputandum" (taste cannot be debated), underlies the social constructivist emphasis on the historically changing and culturally relative nature of beauty (see Kubovy, 2000).Most modern philosophical analyses, however, reject the objective versus subjective distinction. Instead, they suggest that a sense of beauty emerges from patterns in the way people and objects relate (e.g., Ing...
