Fig. 2.

Movement duration and end-point movement variability in each condition for the 45° and 135° targets across subjects in experiment 1. A: movement duration in the 4 conditions for both targets. B: natural logarithm of end-point variance in the 4 conditions for both targets. Both panels show estimated fixed effect coefficients with their confidence intervals in a model using mixed models with condition and target as main effects and target × condition interactions; see text for details. Asterisks show significance of difference between conditions for both targets (Bonferroni corrected): *P < 0.05, ***P < 0.0005; see text for additional comparison results.
