Figure 2.

Bar graphs representing the changes in (A) target-tracking error and (B) target-tracking variability with training. The target-tracking error and variability were evaluated from the data (2-minute block) collected during the initial and final part of target-tracking practice at various training sessions (early – 2^nd session, post-intervention, and follow-up). Error bars represent 95% confidence intervals (between-stride). Note that the subject was able to reduce the target-tracking error and variability with practice, even though the templates for target-tracking were different at the 3-time points.
