  1. Parameter estimates are given for factor levels given in squared brackets with respect to AP COORDINATION PATTERN and OFF tACS CONDITION as reference categories. Asterisks indicate level of significance at ***p < 0.0001, **p < 0.01, *p < 0.05 estimated for LME models with Satterthwaite approximation. For both models the number of observations was 912 for 19 groups, i.e. subject.
