    Purpose – The purpose of this study is to examine how consumer personality trait impulsiveness influences trustworthiness evaluations of online-offers with different trust-assuring and trust reducing elements by measuring the brain activity of consumers. Shoppers with high degrees of impulsiveness are referred to as hedonic shoppers, and those with low degrees are referred to as prudent consumers. Design/methodology/approach – To investigate the differences between neural processes in the Brains of hedonic and prudent shoppers during the trustworthiness evaluation of online-offers, the present study used functional magnetic resonance imaging (fMRI) and region-of interest analysis to correlate neural activity patterns with behavioral measures of the study participants. Findings – Drawing upon literature reviews on the neural correlates of both trust in online settings and consumer impulsiveness and using an experimental design that links behavioral and fMRI data, the study shows that consumer impulsiveness can exert a significant influence on the evaluation of online-offers. With regard to brain activation, both groups (hedonic and prudent shoppers) exhibit similar neural activation tendencies, but differences exist in the magnitude of activation patterns in brain regions that are closely related to trust and impulsiveness such as the dorsal striatum, anterior cingulate, the dorsolateral prefrontal cortex and the insula cortex. Research limitations/implications – The data provide evidence that consumers within the hedonic group evaluate online-offers differently with regard to their trustworthiness compared to the prudent group, and that these differences in evaluation are rooted in neural activation differences in the shoppers’ brains.

    The integration of neuroscientific methods in Information Systems(IS) research to better understand how the brain interacts with IS relevant context has gained in importance. Many papers that highlight the potential of neuroIS and that discuss methodological issues associated with using functional brain imaging already exist. However, neuroIS researchers have to keep in mind that the emergence of complex mental processes such as trust in IS contexts is based on activity in a network of brain regions rather than on activity in one area alone. Accordingly, we introduce psycho-physiological interaction (PPI) analysis, a technique that one can use to analyze fMRI data. Specifically, we review how one can conduct PPI analysis, provide a concrete research example, and show how this analysis can inform IS trust research. Thus, we introduce neuroIS Researchers working in the domain of functional brain imaging to advanced fMRI analyses methods and show, based on the example of trust, how These methods can enhance our understanding of the nature of IS constructs.

    The Effect of Glucose Consumption on Customers' Price Fairness Perception

    Price fairness research has not yet developed a comprehensive explanation of what drives customers' perception of price fairness. Here, we show that customers perceive product prices as having greater fairness after glucose intake, thus identifying a biological driver of customer price fairness perception. We also show that there is no linear effect of glucose consumption on customer price fairness perception, and that glucose intake does not lead to significant differences in the mood states of participants. Our results demonstrate how the integration of neuroscience concepts and theories can provide deeper insights on automatic and unconscious processes, hence making it possible for marketing and consumer researchers to better understand customers' price fairness perceptions.

    Neural Correlates of Impulsive Buying Tendencies during Perception of Product Packaging

    Research has shown that people differ in their susceptibility to impulsive buying. The appeal of product packaging has the potential to trigger impulsive buying even for consumers with no intention to make a purchase. The aim of the present study was to investigate whether individual differences in consumers' impulsive buying tendencies affect unconscious neural responses during the perception of product packaging. Functional magnetic resonance imaging (fMRI) was applied to measure neural responses to the perception of product packages in participants with different impulsive buying tendencies. The results of the study support and expand prior research in impulsive and reflective information processing and behavior. First, attractive versus neutral packages evoked more intensive activity changes in brain regions associated with an impulsive system. Second, attractive and unattractive versus neutral packages led to less intensive activity changes in regions associated with a reflective system. Third, attractive packages activated regions associated with reward, whereas unattractive packages activated regions associated with negative emotions. The results suggest that there is indeed a corresponding relationship between stronger impulsive buying tendencies and activity in brain areas associated with impulsive and reflective processes.

    Consumer Neuroscience - An Overview of an Emerging Discipline with Implications for Consumer Policy
    (SP Birkhäuser Verlag, 2011-03)
    Kenning, Peter
    ;
    In recent years, interest in the integration and application of neuroscientific theories, concepts, findings and methods to the research discipline of consumer behavior has been increasing. The sub-discipline of consumer neuroscience that has resulted from that interest belongs to the innovative approach of neuroeconomics. Consumer neuroscience investigates problems of consumption and marketing through methods and findings from neuroscience. Conventional research in consumer behavior and marketing necessarily looked at the human organism as being a "black box" which cannot be assessed directly, or physiologically. This was a time when research mainly used theoretical constructs to interpret these bodily processes and resulting behavior. More recently, however, modern techniques and methods in neuroscience have facilitated a far more direct look into the "black box" of the organism as the basis for the sub-discipline of consumer neuroscience. Consumer neuroscience, therefore, can significantly benefit research in the field of consumer behavior, particularly in the attempt to better understand human behavior in decision-making processes. Although consumer neuroscience is a fledgling discipline, it constitutes a complementing advancement toward more comprehensive testing and expansion of theory. Against this background, the primary goal of the paper is to provide an overview of methods, findings, and implications of selected studies in consumer neuroscience. Furthermore, we integrate aspects of consumer policy and neuroethics, discussing the possible implications of these insights for consumer protection.
