1. A computer-implemented method of measuring emotional response of at least one subject of a plurality of subjects to a specific sensory stimulus, comprising the steps of:

  • establishing a plurality of basic emotions for measurement, including one or more positive affect emotions and one or more negative affect emotions;

    presenting the subject with the sensory stimulus;

    for each basic emotion, presenting the subject with a computer-generated display comprising interactive animated visual images representative of a metaphorical concept corresponding with the basic emotion;

    receiving input from the subject via a computer interface whereby the subject is enabled to adapt the animated visual images to accord with an emotional response to the sensory stimulus;

    a computer-implemented processor converting the received input to a corresponding quantitative emotional response value for each basic emotion;

    the computer-implemented processor performing a statistical analysis employing a latent variable mathematical model of the quantitative emotional response values of the plurality of subjects to identify one or more latent constructs, each of which comprises a subgroup of the plurality of basic emotions; and

    the computer-implemented processor generating a visual presentation comprising distinct representations of each one of the quantitative emotional response values for the plurality of basic emotions within the identified latent constructs, in which emotional responses of the plurality of subjects in respect of each one of the plurality of basic emotions within the identified latent constructs is visually distinguishable relative to all others of the plurality of basic emotions.
