An error-tuned model for sensorimotor learning

A. The lifting paradigm used in [23]. Participants lifted a U-shaped object by alternating between the right-hand and left-hand grasp points in four blocks. B. The peak roll angle (tilt) of the object (top panel), as well as the compensation torque (bottom panel). Perfect compensation required ±550 N.mm depending on the context. Data is plotted in black and the fits for the ETM and CDM are plotted in red and blue, respectively. The best-fit parameters for the models (see Methods for details) are: α0 = 0.87, β0 = 0.74, β180 = 0.17, c180 = 0.0, x° = 0.66, and k = 15.68 for the ETM, and α0 = 0.92, β0 = 0.79, β180 = 0.00, c180 = 0.49, x° = 1.00 and k = 15.68 for the CDM.
