 Skin conductance (electrodermal activity): Skin conductivity indicates emotional arousal because increased sweat production by certain emotions increases the skin conductivity level. fMRI: this technology generates neuro-images of brain activities. fMRI can detect neurophysiological changes in the brain and thereby help determine the degree to which a person is aroused by the stimulus. For example, increased amygdala activity can be an indication of fear. Facial Action Coding System (FACS): this method uses the taxonomy of the face to measure movements of facial muscles. For example, the contraction of the orbicularis oculi muscle is an indication of happiness. Maximally Discriminative Facial Movement Coding System: this system is mostly used to measure the emotional responsivity of young children by corresponding universally recognized facial expressions to emotions. For example, lowering eyebrows indicates emotions of anger. Self-report: this method asks the participants to rate their valence and arousal level through questionnaires such as the Emotionally Expressivity Scales and the Berkley Expressivity Questionnaire. Studies have shown that self-report might not correspond to objective measures such as fMRI.
