A Google Tech Talk from Innerscope‘s (ex MIT post grads) Andre Marquis about their low-cost solution to tracking emotional responses to media. The main section is about traditional advertising, however, the insights apply to all types of content, and Andre covers web usability later in the talk as well as a reasonably detailed case study of work Innerscope has done for YouTube in Europe. This is a pretty good introduction to neuroscientific approaches to messaging, attention and the implications this has on how we order our messaging. You’ll love this. Really, you will.
