As Ravaja and Somervuori, (2013) discuss, one reason for the lack of research on
emotions and pricing is that, in the past, researchers have had to rely on self-reports and observed behavioral measures. These methods may be problematic because they rely on the participant’s ability to reconstruct emotions and thoughts, or on the observer’s ability to identify the emotions.
The use of psychophysiological measures (e.g. fMRI, EEG) in neuroeconomic research has enabled researchers to tap into a new dimension of studying the consumer at the level of the brain, which may lead to a more complete and objective understanding of consumer behavior
