Sensory realignment can operate independently of sensory weights. A: in experiment 1, there was no relationship between P endpoint shift (ΔŷP, includes motor adaptation; open circles and dashed line) or proprioceptive realignment (ΔŷP from the sensory subexperiment; solid circles and solid line) and wV early in the baseline block, suggesting that sensory weighting and realignment are separable processes that can operate independently. B; in experiment 2, without endpoint visual feedback to necessitate that proprioception be regarded as the misaligned modality to succeed at the task, P endpoint shift (ΔŷP, motor adaptation component = 0, i.e., proprioceptive realignment) was strongly correlated with early baseline wV (correlation r = 0.55, P = 0.01), suggesting that weighting and realignment do operate in conjunction (high wV associated with large ΔŷP) in this situation. *Includes both motor adaptation and proprioceptive realignment.
