Notes: The cells of the upper triangle (top-right) report the number of peaks until seven, where the correlation between emotions is statistically significant. The dark gray cells stand for negative correlations, while the light gray ones stand for positive correlation. See Appendix for correlation coefficients. The cells of the lower triangle (bottom-left) show their significance levels using asterisks to indicate whether p < 0.05 (*), p < 0.05 (**) or p < 0.001 (***)
