When the human motor system adapts to novel dynamics of the arm during reaching, hand trajectories tends to converge toward a roughly straight line. This straight line is thought to be the desired trajectory of the system. Trial-to-trial changes in performance are well described by a first order state-space model: errors in a given trial affect performance on the subsequent trial as a function of the distance in state space between the two trials. This function describes the generalization… CONTINUE READING
