ANOVA, analysis of variance; maxAp, maximum grip aperture; maxH, maximum wrist height.
The table reports all significant effects showed by the repeated measures ANOVAs on z-scores of grasping asynchrony, reaction times, movement times and wrist and pre-shaping kinematics (maxH and maxAp), having stimulation site (aIPS/vertex) × action-type (complementary/imitative) × clip-type (correction/no-correction) × movement-type (power/precision grip) as within-subject factors (see Methods section). In bold and italics are the significant interaction between action-type × stimulation site on grasping asynchrony described in the main text.
