A method of measuring emotional response of at least one subject to a specific sensory stimulus comprises establishing ( 202 ) a plurality of basic emotions for measurement, including one or more positive affect emotions and one or more negative affect emotions. The subject is presented ( 302 ) with the specific sensory stimulus, and for each basic emotion is further presented ( 306 ) with a computer-generated display comprising interactive animated visual images representative of a metaphorical concept corresponding with the basic emotion. Input is then received ( 308 ) from the subject, who is enabled to adapt the animated visual images to accord with an emotional response to the sensory stimulus. The received input is converted to a corresponding quantitative emotional response value for each basic emotion. The quantitative emotional response value may be a difference value derived from a change in emotional state of the subject and based upon an initial calibration of emotional state performed prior to presenting the subject with the sensory stimulus. A visual presentation ( 1000 ) is generated, which comprises representations ( 1004, 1012, 1014 ) of the quantitative emotional response values for each of the plurality of basic emotions, whereby the relative emotional response of the subject in respect of each basic emotion is visually distinguishable. |
