“…Recent calls for an improved understanding of the basic mental mechanisms underlying WTP calculations have proposed to include neurobiological explorations of how the brain calculates values and instigates choice behavior. Still, in spite of the rapidly expanding research fields of neuroeconomics (Rolls, 2000 ; Camerer et al, 2005 , 2016 ; Kenning and Plassmann, 2005 ; Rustichini, 2005 ; Kable and Glimcher, 2009 ; Wilhelms and Reyna, 2014 ; Levy and Glimcher, 2016 ), neuromarketing or consumer neuroscience (Ariely and Berns, 2010 ; Fisher et al, 2010 ; Plassmann et al, 2012 , 2015 ; Smidts et al, 2014 ; Ramsøy, 2015 ; Hsu, 2017 ; Lee et al, 2017 ). In these multidisciplinary efforts, any exact understanding of the neural or psychological mechanisms underlying WTP calculations is still woefully lacking (Plassmann et al, 2012 ).…”
