Spillover effects of sensory stimulation

Abstract

Purpose This paper aims to propose the sensory stimulation spillover effect phenomenon, defined as the process by which sensory stimulation in one area generates positive impressions and favorably impacts opinions in other areas. Specifically, this paper demonstrates that the spillover effect of sensory priming via an advertised brand impacts the viewer’s self-brand connections (the mental representation of a brand connected to an individual’s self-concept), brand attitude and brand purchase intention. Design/methodology/approach Across six experiments, 883 participants considered advertised brands from diverse product categories (food snacks, electronics and detergent). The multisensory prime in Studies 1–3 uses positively valenced sensory imagery and text, whereas the multisensory prime in Studies 4–6 is a sensory imaging task. Studies 1–4 examine the spillover effect of the multisensory prime on consumers’ self-brand connections, as well as downstream brand-related variables. Studies 5 and 6, respectively, examined the moderating roles of advertising appeal, regulatory focus (promotion vs prevention) and cognitive versus affective tone. Findings Results provide robust evidence of the proposed sensory stimulation spillover effect. Sensory priming strengthens self-brand connections and positively impacts brand attitude and purchase intention; self-brand connections mediate the relationship between a multisensory prime and brand attitude and purchase intention. The sensory stimulation spillover effect is stronger when advertisements have a promotion (vs prevention) focus and particularly for participants with a stronger intrinsic promotion (vs prevention) orientation, as well as for advertisements with an affective (vs a cognitive) tone. Research limitations/implications The authors manipulated sensory stimulation using visual images and text as well as using a multisensory-imaging task. Future work can explore the use of actual sensory stimulation, and retail spaces or public venues may provide opportunities for field experiments to study sensory stimulation in situ. Practical implications The research focuses on spillover effects in an advertising context with broader implications for consumers’ in-store shopping experiences based on multisensory store architecture and atmospherics, as well as online shopping that is impacted by multisensory information. Originality/value This paper introduces the phenomenon of sensory stimulation spillover effect, the process by which sensory stimulation in one area generates positive impressions and favorably impacts opinions in other areas and demonstrates that multisensory priming strengthens self-brand connections and downstream brand-related variables, with self-brand connections as the mediator. The results are robust across multiple product categories and are contingent upon the type of advertising appeal. The research focuses on spillover effects in an advertising context with broader implications for consumers’ in-store shopping experiences based on multisensory store architecture and atmospherics, as well as online shopping which is impacted by multisensory information.
