| image visualization | Behavioral | 20 images (from the IAPS-international affective picture systems) are presented to the subject. He has to determine the hedonicity of each picture. |
|
| psychophysiological assessment | Behavioral | during the olfaction assessment and the image visualization, skin conductance reactivity (SCR) is recorded to assess unconscious emotional reactivity |
