1Table A8 reports the results of Model 4, which extended Model 3 by adding cognitive ability as control variable (Formula: Response ~ Condition/(Group*Musical rhythm perception ability + Cognitive ability) + (1 + Duration-Intensity + Control-Duration || participant) + (1 | item). Level of significance: * p < 0.05, ** p < 0.01, *** p < 0.001. Not different from Model 3, the results of Model 4 suggest highly significant effects of musical rhythm perception ability on the duration (p = 0.02) and the control condition (p = 0.008). Intensity was, just as in Model 3, not modulated by musical rhythm perception ability, and there were, again, no interactions of any condition and group, and neither any three-way interactions of any condition with group and musical rhythm perception ability. Altogether, there were no significant effects of cognitive ability. Model comparisons revealed that Model 4 was not better than Model 3 (χ2 = 8.05, p < 0.23).
