The emerging discipline of neuroeconomics employs methods originally used in brain research for investigating economic problems, and furthers the advance of integrating neuroscientific findings into the economic sciences. Neuromarketing or consumer neuroscience is a sub-area of neuroeconomics that addresses marketing relevant problems with methods and insights from brain research. With the help of advanced techniques of neurology, which are applied in the field of consumer neuroscience, a more direct view into the ''black box'' of the organism should be feasible. Consumer neuroscience, still in its infancy, should not be seen as a challenge to traditional consumer research, but constitutes a complementing advancement for further investigation of specific decision-making behavior. The key contribution of this paper is to suggest a distinct definition of consumer neuroscience as the scientific proceeding, and neuromarketing as the application of these findings within the scope of managerial practice. Furthermore, we aim to develop a foundational understanding of the field, moving away from the derisory assumption that consumer neuroscience is about locating the ''buy button'' in the brain. Against this background the goal of this paper is to present specific results of selected studies from this emerging discipline, classified according to traditional marketing-mix instruments such as product, price, communication, and distribution policies, as well as brand research. The paper is completed by an overview of the most prominent brain structures relevant for consumer neuroscience, and a discussion of possible implications of these insights for economic theory and practice.

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.

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.
