Chromatic and spatial image statistics predict infants’ visual preferences and adults’ aesthetic preferences for art

Aesthetics has been characterized as a triadic interaction of perceptual, emotional, and conceptual neural systems (e.g., Chatterjee & Vartanian, 2014). There has been much empirical effort to identify the visual features that contribute to the perceptual component of this triad (e.g., Mather, 2020). Here, we measured infants’ visual preferences and adults’ aesthetic preferences for 40 of van Gogh's landscape paintings and investigated the contribution of the chromatic and spatial image statistics of the art to infants’ and adults’ responses. We found that infants’ and adults’ responses were significantly related: infants looked longer at the art that the adults found more pleasant. We also found that our combination of chromatic and spatial image statistics could account for around two thirds of the variance in infant looking and adult pleasantness ratings. The amount of variation in the luminance and saturation of the art's pixels contributed to both infants’ visual preferences and adults’ aesthetic preferences, potentially identifying two “perceptual primitives” of aesthetics that can be traced back to early sensory biases in infancy. We also identified important differences in the types of image statistics that predict infants’ and adults’ responses. We discuss the findings in relation to theories of aesthetics, natural scene statistics, and infant vision and perception.
