B. Models fit to displacement of each gesture (reported in Sections 3.2 and 3.3)
 
1. Model structure

lmer (DISP ~ Boundary*Vtype*Information +
(PKVEL +) Ctype +
(1+Boundary*Vtype*Information|Subject),
control=lmerControl(optimizer='optimx', optCtrl=list(method='nlminb')))

* In models factoring in the mutual dependence of DISP on PKVEL (Section 3.3), PKVEL (marked in red) was included as an additional control predictor.

 
2. Model outputs

* Significant effects are marked in shaded cells.
