BACKGROUND

Human decision-making is not solely driven by rationality. Indeed, it is also driven by subconscious processes, emotions and interoceptive states which all can be influenced by multisensory cues in the environment. While the influence of our senses of sight, smell, and taste on food perception and valuation, is well-studied, sound is still underrepresented in this research area. However, auditory stimuli such as ambient sound is a relatively inexpensive and convenient way to promote healthier food choices among consumers. For example, sound may guide consumers’ visual attention towards desired options (e.g. healthy food products) and thereby increasing the probability of them buying it. Likewise, sound and music can activate the brain’s reward centers of consumers potentially causing augmented incentive salience towards and hedonic experience of healthy food. Such sensory nudges may have a particular impact in Western consumers, but it may be different in other cultures such as in China.

AIM

The aim of this PhD project is to explore how ambient sounds can influence psychological, physiological, and neurological drivers of healthy food choices across different cultures. By studying these implicit measures, we can help the marketers in the food industry design, optimize, and promote healthier products that are at the time more attractive to consumers in different market segments.

 

RESEARCH OUTLINE

The project will include laboratory studies, involving biometric measurements (eye-tracking, skin conductance, and heart rate) neuroimaging (EEG/fMRI), as well as ecologically-valid consumer studies in real-life contexts. The research will be conducted in both Denmark and China with Danish and Chinese consumers respectively.
