Experiment 2
In experiment 2, trials before the introduction of the force field were considered baseline trials. As for experiment 1, we used a linear mixed model analyses on each of the extracted parameters (MD, PL, and MS) with Arm (left and right) and force field presence (FF) as fixed effects, and a random intercept per participant. We also extracted MS on trials immediately following a catch trial and performed a linear mixed model analysis with Arm and Trial number as fixed predictors. Finally, for the catch trials, we performed a paired-wise Finally, to determine whether participants used co-contraction, we computed the average EMG level in a window of 100 ms before movement onset for the 10 first and 10 last null field trials of experiment 2. We performed a repeated measure ANOVA with arm and position (early vs late adaptation) as within factor parameters. Paired
