Correlation coefficients between each index and ‘like-dislike’ impression scores. Positive correlations mean the more pleasant (like) the impressions, the greater the indices. No significant correlations were observed. Changes from baseline: ΔHR, heart rate; ΔSV, stroke volume; ΔCO, cardiac output; ΔSBP, systolic blood pressure; ΔDBP, diastolic blood pressure; ΔMBP, mean blood pressure; ΔTPR, total peripheral resistance; ΔHF, high frequency HRV; ΔLF, low frequency HRV; and ΔVLF, very low frequency of HRV. HRV, heart rate variability.
