Notes: Results were obtained using repeated-measures ANOVA with the within-participant factors of “Stimuli type” (dynamic stimuli, static stimuli) and “Pain” (painful, non-painful), as well as the between-participants factor of “Group” (High-AQ, Low-AQ).
Significant comparisons (p < 0.05) are indicated in boldface.
