We performed experiments to determine the relative contributions of vision and proprioception to sensory adaptation to in-depth prismatic distortion. We determined whether these effects were consistent with the optimal reliability-based calibration theory which posits that adaptation is the largest in the least precise modality.
Overall, these results are consistent with the hypothesis that information from vision and proprioception is calibrated optimally to minimize estimated-position uncertainty.
These results indicate that the entire perception-action loop is plastic, with a specific time constant for each element. The time constant (which determines the extent of adaptation) of the visual or proprioceptive component may depend on the experimental conditions and on the robustness of the component.
