Figure 1.

Examples of feedback presented to the participants. Feedback regarding the peak velocity and the timing of the peak velocity was provided after each trial. Large gray blocks indicate the velocity peak location target, while the bar chart at the top-right corner indicates peak y-velocity magnitude. Feedback was provided on the modality (cursor or hand) that matched the baseline, where the horizontal line indicated the location of the peak velocity in this modality. Left, Velocity peak location is within the target, but the movement was too fast (unsuccessful trial). Middle, Velocity peak location is too early, but the movement speed is within the target (unsuccessful trial). Right, Successful trial.
