It is discloses a method and system for measuring and assessing the impact of non-verbal responses of a respondent to a stimulus, the method comprises the steps of presenting a reference stimulus to the respondent recording immediate non-verbal responses via an imaging device to said presented reference stimulus presenting a stimulus under test to the respondent recording immediate non-verbal responses via an imaging device to said presented stimulus under test presenting a questionnaire with questions on the stimulus under test to the respondent obtaining verbal responses to the questions immediately transmitting the recorded image of said non-verbal responses to the reference stimulus and the stimulus under test across a communications network to an image processing unit and after having received said images at said image processing unit automatically calculating emotion probabilities of the non-verbal responses of the respondent from said images and calculating a emotional intensity score derived from the emotional probabilities. The method described in this invention bridges the gap between verbal self-report and autonomic non-verbal emotional response measurement methods while adding an objective and scientific analyze of non-verbal response to a stimulus.
