Table 1. ANOVAs for the features of the intensity ratings.

Outcomes for the main effects and interactions from the repeated measures ANOVA performed for the average (two first rows) and dynamical (four last rows) features of the intensity ratings. Partial eta squared (${\eta }_P^2$) are indicated for the effect sizes and the p- values smaller than the significance level of 0.05 are in bold.
