Abstract: 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.
