Changes in proprioceptive biases after training with misaligned visual feedback of the hand compared with aligned visual feedback of the hand as % of the distortion introduced. A positive value indicates that subjects recalibrated proprioception in the expected direction. In A, changes in biases after training with a rotated cursor are shown for each reference marker relative to the trained target direction (0° distance) from both S1 (solid black line) and S2 (dashed gray line). Open symbols represent errors made at a similar location to the reach training target from S1 (open black circle) or S2 (open gray circle). In B, changes in biases after training with a Cursor Decrease (solid black line) and after training with a Cursor Increase (dashed gray line) are shown at each reference marker relative to the trained target direction (0° distance). Error bars reflect SE.
