determination of olfactory sensitivity through olfactory threshold assessment (butanol) determination of hedonicity and intensity of 16 usual odors
20 images (from the IAPS-international affective picture systems) are presented to the subject. He has to determine the hedonicity of each picture.
during the olfaction assessment and the image visualization, skin conductance reactivity (SCR) is recorded to assess unconscious emotional reactivity
