The article by Reber, Schwarz, and Winkielman proposes that aesthetic pleasure is a function of the perceiver's processing dynamics. They argue that the more fluently an object can be processed, the more positive the aesthetic response. The authors 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. They also discuss the role of visual and semantic priming in increasing judgments of aesthetic pleasure. The proposal provides an integrative framework for studying aesthetic pleasure and highlights the interplay between early preferences and cultural influences on taste, preferences for both prototypical and abstracted forms, and the relation between beauty and truth. The authors contrast their theory with theories that trace aesthetic pleasure to objective stimulus features, arguing that beauty is grounded in the processing experiences of the perceiver, which are influenced by both stimulus properties and the perceiver's cognitive and affective processes. They support their proposal with empirical evidence from social and cognitive psychology and empirical aesthetics, demonstrating that variables that facilitate stimulus processing result in more positive affective reactions and more favorable judgments of preference. The article also explores the role of processing expectations and attributions in moderating the impact of fluency on aesthetic judgments.The article by Reber, Schwarz, and Winkielman proposes that aesthetic pleasure is a function of the perceiver's processing dynamics.
