Simulated Interlimb Generalization. (a) Adaptation and (b) interlimb generalization with a curl field. (c) Experimental evidence (reproduced from Criscimagna-Hemminger et. al. ‘03) showing early exposure, adaptation (late training) and interlimb generalization (test) in a clockwise (Extrinsic) and counter-clockwise (Intrinsic) field. (d) Simulated data with our model demonstrating similar findings as the result of a small estimated external field and large misestimates in limb parameters. (e) Increasing the body’s uncertainty (decreasing α to 0.1) our model predicts asymmetric generalization. The top plots displays generalization from the dominant to the nondominant limb, while the bottom plots displays generalization from the nondominant to the dominant limb with little transfer of the adapted skill.
