How pretty faces sell boring products - Idézet:
conditioning our brain's reward system
Bray and O'Doherty's report in the Journal of Neurophysiology illustrates the biology behind the selling power of beautiful models in advertisements for mundane products, and should be of interest to neuro-marketers everywhere. PDF here.

Prediction error related activity in the nucleus accumbens.
A: voxels in the nucleus accumbens were significantly activated in a contrast of prediction error signals for attractive faces vs. unattractive faces, voxels in yellow are significant at P <>

Twenty-six adults participated in the study, in which they were given $20 to spend on a series of products that would be shipped to them. If they made no purchases, they would be able to keep the money.
The products and their prices appeared on a computer screen that the participants viewed while lying in an fMRI scanner.
The researchers found that when the participants were presented with the products, a subcortal brain region known as the nucleus accumbens that is associated with the anticipation of pleasure was activated.
When the subjects were presented with prices that were excessive, two things happened: the brain region known as the insula was activated and a part of the brain associated with balancing gains versus losses -- the medial prefrontal cortex -- was deactivated.

Idézet:
For the first time, researchers have used functional magnetic resonance imaging (fMRI) to determine what parts of the brain are active when people consider whether to purchase a product and to predict whether or not they ultimately choose to buy the product. The study appears in the journal Neuron and was co-authored by scientists at Carnegie Mellon University, Stanford University and the MIT Sloan School of Management.
This paper is the latest from the emerging field of neuroeconomics, which investigates the mental and neural processes that drive economic decision-making. The results could have a profound impact on economic theory, because the decision of whether to purchase a product is the most basic and pervasive economic behavior.
Previous imaging studies have found that separate parts of the brain are activated when people are confronted with financial gains versus financial losses. The authors of this latest study believed that distinct brain regions would be activated when people were presented with products they wish to purchase (representing a potential gain) and when they were presented with those products' prices (representing a potential loss). The researchers wanted to see if they could then use this information to predict when a person would decide to buy a product, and when they would pass it up.
