Beyond Visual Aesthetics: The Role of Fractal-scaling Characteristics across the Senses†

Abstract

The investigation of aesthetics has primarily been conducted within the visual domain. This is not a surprise, as aesthetics has largely been associated with the perception and appreciation of visual media, such as traditional artworks, photography, and architecture. However, one doesn’t need to look far to realize that aesthetics extends beyond the visual domain. Media such as film and music introduce a unique and equally rich temporally changing visual and auditory experience. Product design, ranging from furniture to clothing, strongly depends on pleasant tactile evaluations. Studies involving the perception of 1/f statistics in vision have been particularly consistent in demonstrating a preference for a 1/f structure resembling that of natural scenes, as well as systematic individual differences across a variety of visual objects. Interestingly, comparable findings have also been reached in the auditory and tactile domains. In this review, we discuss some of the current literature on the perception of 1/f statistics across the contexts of different sensory modalities.
