Coke Neuromarketing

Roger Dooley provides a number of examples of Coke neuromarketing.  I had been sensing that there was a decrease in the use of these technologies to understand market engagement, but this article says otherwise.  In part that some well known companies like Unilever and Coke are requiring subconscious methods to be used with product and packaging evaluation.  I know of other large CPG companies that re actively using the same approaches.   The same companies are reluctant to provide details because of the implied invasive form of the methods.
