Wine tasting: a neurophysiological measure of taste and olfaction interaction in the experience

In the last years have been provided evidences of sensory–sensory connectivity and influences of one modality over primary sensory cortex of another, a phenomena called crossmodality. Typically, for the wine tasting, sommeliers in addition to the use of the gustation, by the introduction of the wine into the mouth, employ the stimulation of the olfactory system both through a direct olfactory stimulation (by the nose) and a retro-nasal pathway (inhaling air while swirling the wine around in the mouth). Aim of the present study was to investigate the reaction to the wine gustation with and without the direct olfactory contribution, through an electroencephalographic index of approach or withdrawal (AW) motivation, and an autonomic index (Emotional Index – EI), deriving from the matching of heart rate and galvanic skin response activity and considered an indicator of emotional involvement. Results showed a statistically significant increase of the EI values in correspondence of wine tasting with the olfactory component (p<0.01) in comparison to the tasting without the direct olfactory contribution, and a trend of greater approach attitude was reported for the same condition. Data suggest an interaction of the two sensory modalities influencing the emotional and the cognitive aspects of wine tasting experience in a non-expert sampl

Message framing, non-conscious perception and effectiveness in non-profit advertising. Contribution by neuromarketing research

Advertising for non-profit organizations through television commercials is a valuable means of communication to raise awareness and receive donations. When it comes to social aspects, personal attitudes such as empathy are significant for reinforcing the intention to donate; and the study of eliciting emotions has critical attention in the literature, especially some types of emotion, such as guilt which mediates empathy. Different methodologies have been used to measure consumer emotions when faced with TV ads stimuli: mainly traditional techniques such as interviews or questionnaires after the ads viewing. In the last ten years, there has also been a great interest in new neuroscience techniques applied to measure emotional and cognitive reactions by physiological signals, frame by frame. Our research has applied neuromarketing technologies during the observation of a UNHCR commercial promoting legacy calls. The objective was to study cognitive and emotional reactions in order to increase the effectiveness whilst having the possibility to verify the results by measuring the benefits in terms of calls from contributors. The purpose of this research is to empirically prove the impact in calls thanks to changes in the message framing strategy in non-profit advertising suggested and measured by neuromarketing techniques. Particularly we measured the cerebral activity through an electroencephalogram to obtain an Approach-Withdrawal Index (AW); the heart rate and galvanic skin response through different sensors in the palm of one hand, to obtain an Emotional Index (EI), and finally, eye fixations through an eye tracker device to obtain the visual attention on key visual areas of the ads. After these indicators' recordings on a sample of subjects, some suggestions to modify the advertising were made to create a more effective campaign. The results compared, those elicited by the first version of the spot (LVE) and those by the second version (HVE), confirmed that (1) the number of sellable and legacy calls increased with the message framing strategy modified in the second spot (HVE), (2) a lower cognitive and emotional reactions have been obtained in the final section of HVE, (3) the visual attention on the key information of the phone number to call, in the final call to action frames(CTA), was higher in HVE than in the first version of the spot (LVE), (4) the cognitive approach increased during the same CTA frames in HVE

Eeg frontal asymmetry related to pleasantness of olfactory stimuli in young subjects

It is widely known, in neuroscientific literature, that the brain prefrontal cortex activity asymmetry is closely linked with the pleasantness emotion experienced by the subject during a sensorial stimulation. Thus, from the electroencephalographic (EEG) signal it is possible to estimate the approach/withdrawal index, and this index has been largely investigated and validated in scientific literature, regarding visual and acoustic stimuli. In this work, we present an innovative study aimed to prove, in a systematic way, that such brain AW index is actually correlated with the “pleasant” or “no-pleasant” perception also of olfactory stimuli, conveniently produced by standardised methods in the sensory specific scientific literature. In particular, we recorded the electroencephalographic (EEG) signal from a group, gender balanced, of 24 healthy and no-smokers subjects during the perception of ten different smells, presented by means of the “Screening test-odour identification” set (Sniffin’ sticks, Burghart). The cerebral AW indexes of all the subjects, for each odorous stimulus, were compared with the appreciation numeric score assessed by the subject during the experiment, by performing a statistical correlation test. Findings show that it is possible to evaluate the pleasantness or no-pleasantness of odorous substances by means of the analysis of EEG signals collected during the presentation of such substances, making way for new applications of such measure kind in experimental environments more and more ecological, as the typical ones of the marketing research areas

Forefront users’ experience evaluation by employing together virtual reality and electroencephalography: a case study on cognitive effects of scents

Scents have the ability to affect peoples’ mental states and task performance with to different extents. It has been widely demonstrated that the lemon scent, included in most all-purpose cleaners, elicits stimulation and activation, while the lavender scent elicits relaxation and sedative effects. The present study aimed at investigating and fostering a novel approach to evaluate users’ experience with respect to scents’ effects through the joint employment of Virtual Reality and users’ neurophysiological monitoring, in particular Electroencephalography. In particular, this study, involving 42 participants, aimed to compare the effects of lemon and lavender scents on the deployment of cognitive resources during a daily life experience consisting in a train journey carried out in virtual reality. Our findings showed a significant higher request of cognitive resources during the processing of an informative message for subjects exposed to the lavender scent with respect to the lemon exposure. No differences were found between lemon and lavender conditions on the self-reported items of pleasantness and involvement; as this study demonstrated, the employment of the lavender scent preserves the quality of the customer experience to the same extent as the more widely used lemon scent

Neuroelectrical Brain Imaging Tools for the Study of the Efficacy of TV Advertising Stimuli and their Application to Neuromarketing

In this book the authors describe their original research on the potential of both standard and high-resolution electroencephalography (EEG) for analyzing brain activity in response to TV advertising. When engineering techniques, neuroscience concepts and marketing stimuli converge in one research field, known as neuromarketing, various theoretical and practical aspects need to be considered. The book introduces and discusses those aspects in detail, while showing several experiments performed by the authors during their attempts to measure both the cognitive activity and emotional involvement of the test subjects. In these experiments, the authors apply simultaneous EEG, galvanic skin response and heart rate monitoring, and show how significant variations of these variables can be associated with attention to, memorization or enjoyment of the presented stimuli. In particular, this book shows the central role of statistical analysis in recovering significant information on the scalp and cortical areas involved, along with variations of activity in the autonomous nervous system. From an economic and marketing perspective, the aim of this work is to promote a better understanding of how mass consumer advertising of (established) brands affects brain systems. From a neuroscience perspective, the broader goal is to provide a better understanding of both the neural mechanisms underlying the impact of affect and cognition on memory, and the neural correlates of choice and decision-making
