Form ‘defines’ function: Neural connectivity between aesthetic perception and product purchase decisions in an fMRI study

In the aesthetics literature, object beauty has been emphasized for its non‐instrumental benefits, in other words, beauty that is ‘rewarding’ in itself, without functional considerations. In the context of consumer products, this study examines the influence of aesthetic perceptions on purchase decisions based on integrating both reward (hedonic) and functional value attribution mechanisms. Brain connectivity analysis of functional magnetic resonance imaging (fMRI) data sheds light on the neural route for the influence of product beauty on purchase. Notably, a significant directional connectivity from brain networks mediating ‘aesthetic perception’ to ‘functional value’ to ‘purchase decision’ shows that the left Amygdala, an emotion‐related region of the aesthetic network, influences all five regions in the functional network, which then influences the purchase network of the brain, thus supporting the utilitarian goals of aesthetic appraisals and the Antonio Damasio's somatic/emotional marker hypothesis. Further, we find clear evidence that the reward (hedonic) network, which also influences the purchase network, receives information from the functional network of the brain, integrating both the non‐instrumental and instrumental value of the product. In other words, beauty in consumer products influences purchase decisions by evoking emotions that importantly define the functional value of products, in addition to their hedonic/reward value uncovered in previous literature. In light of the novel findings, the authors discuss important implications for marketing theory, methodology, and practice. Copyright © 2016 John Wiley & Sons, Ltd.
