Figure 7.

Six scenarios with hand angle (magenta) responding only to the implicit process (red). Explicit strategy (blue) is held constant to simplify the figure. The implicit process (red) is driven by the error (black) between the re-aimed location (blue) and feedback (purple). Additive adaptation pulls the hand away from the re-aimed location and results in decreased error for a rotational perturbation, and increased error under a mirror reversal. The error sign is flipped in quadrants 2 and 4 under a mirror reversal, but not a rotation. Greater transparency of the vectors and endpoints indicates trials further into the past.
