Fig. (2) All data are presented as mean +/- SEM Emotional sweating is expressed as area under the sweating curve (AUC). Singing (p < 0.05), CWT (p <0.01), giving a talk (p <0.05) and mental arithmetic (p < 0.05) induced significant emotional sweating as compared to baseline. Significant differences to neutral affective pictures are indicated by stars. Skin blood flow vasoconstriction (differences of flux values, FV). Compared to baseline, presentation of positive (p < 0.05) and negative pictures (p < 0.05), singing (p < 0.05), CWT (p < 0.05) and mental arithmetic (p < 0.05) led to significant vasoconstriction. Significant differences to neutral affective pictures are indicated by stars. Heart rate increase as compared to baseline (bpm). Singing (p < 0.01), CWT (p < 0.05), giving a talk (p < 0.05) and mental arithmetic (p < 0.01) induced significant increase of heart rate as compared to baseline. Significant differences to neutral affective pictures are indicated by stars. Reduction of PWTT (ms). Singing (p < 0.01), CWT (p < 0.01), giving a talk (p < 0.01) and mental arithmetic (p < 0.05) caused significant reduction of PWTT as compared to baseline. Significant differences to neutral affective pictures are indicated by stars. Activity in trapezius muscle EMG (┬ÁV). Singing (p <0.05), CWT (p < 0.05) and giving a talk (p < 0.05) significantly increased trapezius muscle EMG activity as compared to baseline. Significant differences to neutral affective pictures are indicated by stars. neutr: neutral affective pictures; pos: positive affective pictures; sing: singing; neg: negative affective pictures; CWT: Color-Word interference test; talk: giving a talk; calc: mental arithmetic; *: p < 0.05; **: p < 0.01.
