Table 3 Mean and standard deviation of the acoustic parameters for Low and High arousal condition, results of the dependent t-test comparing both arousal-levels for each acoustic parameter and the correlation coefficient with the PC1; bold p-values represent significant difference; ↑ value is higher in the High than in the Low arousal condition, ↓ value is lower in the High than in the Low arousal condition; bold loading factors represent the parameters showing loading factors higher than 0.700 with the respective PC
