Description: It is said that gradually introducing a perturbation makes motor adaptation more implicit, which should affect the two-rate model's slow process. Here we test that in younger participants adapting to a 30 and 60 degree rotations, as well as in people with mild cerebellar ataxia adapting to a 45 degree perturbation and younger and age-matched controls. All groups adapt both using a gradual and an abrupt perturbation. We test if this within-subject design works (it does) and find that the way the rotation is introduced does not matter for behavioral measures and does not affect the fitted two-rate model parameters either.
