Results of the a disgust ratings of the olfactory stimuli, b the valence ratings of the auditory stimuli, and C the ratings of the emotional states. The ratings are shown for the first (T0) and the second (T1) measurement of the control group (CG) without an intervention and the training group (TG) which received a twenty-day musical training between the two measurements. The four conditions are A0O− (neutral auditory combined with negative olfactory stimulation), A0O0 (neutral auditory combined with neutral olfactory stimulation), A+O− (positive auditory combined with negative olfactory stimulation), and A+O0 (positive auditory combined with neutral olfactory stimulation)
