Trial-by-trial adaptation biases suggests the elbow overreaches to compensate for an underreaching wrist as shown by the opposite signs of elbow and wrist biases. However, no changes in trial-by-trial adaptation behavior were observed between feedback conditions. a Trial-by-trial adaptation bias. b Trial-by-trial adaptation rate.
