The Statistical Determinants of the Speed of Motor Learning
Fig 2
Exemplary model simulations when observation noise (R) is varied.
The left two panels are for a small R value and the right two panels are for a large R value. Other model parameters remain the same in the simulations. The two top panels display the changes of the state variables as a function of trials. The two hidden states, a slow and a fast component, and their sum are plotted separately. The perturbation is applied at the 201th trial. The two bottom panels display the corresponding movement error, i.e., the difference between the model estimate and the actual feedback, as a function of trials.
