The purpose of this paper is to explore the mediating role of emotions in processing scent information in consumer research, using event-related potential (ERP)-based neuroscience methods, while considering individual differences in sense of smell.

Prior research on olfaction and emotions in marketing has revealed mixed findings on the relationship between olfaction and emotion. The authors review earlier studies and present a neuroscience experiment demonstrating the benefits of ERP methods in studying the automatic processing of emotions.

Results demonstrate how emotional processes occurring within 1s of stimulus exposure differ across individuals with varying olfactory abilities. Findings reveal an automatic suppression mechanism for individuals sensitive to smell.

Scent-induced emotions demonstrated through the use of ERP-based methods provide insights for understanding automatic emotional processes and reactions to ambient scents by consumers in the marketplace.

Findings show an automatic suppression of emotions triggered by scent in individuals sensitive to smell. Marketers and retailers should consider such reactions when evaluating the use of olfactory stimuli in promotional and retail strategies.

The authors review past literature and provide an explanation for the disparate findings in the olfaction–emotion linkage, by studying individual differences in response to scent in the marketplace. This is one of the first papers in marketing to introduce the application of ERP in studying consumer-relevant behavior and provide technical and marketing-specific considerations for both academic and market researchers.

This paper aims to review past papers focused on understanding consumer-related topics in marketing and related interdisciplinary fields to demonstrate the applications of electroencephalogram (EEG) in consumer neuroscience.

In addition to the review of papers using EEG to study consumer cognitive processes, the authors also discuss relevant decisions and considerations in conducting event-related potential (ERP) studies. Further, a framework proposed by Plassmann et al. (2015) was used to discuss the applications of EEG in marketing research from papers reviewed.

This paper successfully used Plassmann et al.’s (2015) framework to discuss five applications of neuroscience to marketing research. A review of growing EEG studies in the field of marketing and other interdisciplinary fields reveals the advantages and potential of using EEG in combination with other methods. This calls for more research using such methods.

A technical overview of ERP-related terminology provides researchers with a background for understanding and reviewing ERP studies. A discussion of method-related considerations and decisions provides marketing researchers with an introduction to the method and refers readers to relevant literature.

The marketing industry has been quick to adopt cutting edge technology, including EEG, to understand and predict consumer behavior for the purpose of improving marketing practices. This paper connects the academic and practitioner spheres by presenting past and potential EEG research that can be translatable to the marketing industry.

The authors review past literature on the use of EEG to study consumer-related topics in marketing and interdisciplinary fields, to demonstrate its advantages over-traditional methods in studying consumer-relevant behaviors. To foster increasing use of EEG in consumer neuroscience research, the authors further provide technical and marketing-specific considerations for both academic and market researchers. This paper is one of the first to review past EEG papers and provide methodological background insights for marketing researchers.

The authors broaden the scope of consumer identity by introducing individuals’ olfactory abilities and discussing its impact on perception of the self, consumption behaviors, and consumer well-being.

The authors took a mixed-method approach by embedding smell tests during in-depth interviews. A total of 36 interviews were conducted, involving individuals with varying olfactory sensitivity levels, from decreased sensitivity, normal sensitivity, to heightened sensitivity to smell.

Emergent themes from the interviews include compensation, perception of self and control under three key areas: levels of olfactory sensitivity, the impact of olfactory sensitivity, and the coping strategies used by participants and their families. These findings show that olfactory sensitivity can either enhance or detract from the consumption experience or trigger memories of people, locations or experiences, indirectly affecting consumer well-being and quality of life.

Findings reveal that olfactory abilities not only shape and form an individual’s identity but also have a profound impact on (1) consumption behavior: time spent browsing or lingering, purchase order, product choice, or shopping venue which has immense practical implications for marketers; and (2) consumer well-being: developing coping strategies at both the individual and family level to mitigate the issues faced in consumption.

Unlike the other senses, olfactory abilities are often overseen and neglected. The authors show that olfactory abilities are both relevant and salient. The paper is forefront in demonstrating how sensory abilities shape individuals’ identities and in turn influence consumption practices and experiences.
