The “proximal depiction effect” of indulgent (versus non-indulgent) foods on consumer responses
研究了广告或在线菜单中食品图片的远近（近距vs远距）如何影响消费者反应，发现近距图片会让放纵型食品显得更美味，单次曝光时提高购买意愿，多次曝光则引发饱足感。
Purpose This paper aims to examine the effect of proximal (versus distant) depiction of food products within an advertising or online context on consumer responses across food types (indulgent versus non-indulgent) and display formats that lead to a single exposure (e.g. billboard) versus multiple exposures (e.g. online menu). Design/methodology/approach Five experimental studies, using both implicit and explicit elicitation techniques, demonstrate the effect of proximal food depictions. The paper rules out alternative explanations (portion-size perception and participants’ bodily distance) and controls for several other factors (e.g. visual crowding, body-mass index, dietary restrictions, etc.) Findings The studies find that proximal food pictures are implicitly associated with tastiness more for indulgent (vs non-indulgent) foods; lead to higher purchase intention for indulgent food upon a single exposure driven by enhanced perceived tastiness; and evoke satiation upon multiple exposures. Research limitations/implications This research identifies the effect of spatial proximity of food depiction on consumer responses using different stimuli. Future work could explore the effects in alternate consummatory contexts. Practical implications The findings provide clear instructions to marketers and policymakers on how to tailor consumer responses using spatial distance in depiction of food products, depending on the food type and display format. Understanding the effect of visual food cues will help policymakers devise strategies to counter over-consumption, which increases the risk of non-communicable diseases and reduces consumer well-being (SDG 3, United Nations). Originality/value Introducing a novel pictorial cue (i.e. the spatial distance of product depiction), this paper contributes insights to the literature on implicit associations, visual information processing, satiation, over-consumption and food marketing.
