Results from experiment 1 with trial-by-trial hand-weight perturbations. A: generalization functions from learning loading (H2H − L2H) and unloading (H2L − L2L), the average across both conditions, and the corresponding model-predicted generalization function. Error bars denote SE across participants (same below). B: trial-by-trial changes of trajectory height for a typical participant and the corresponding model predictions. C: the relative learning (LΔ) from previous trials, as estimated from model 2. D: compliance of vertical hand displacement as a function of movement direction. The compliance is estimated from unexpected loading and unloading trials from experiments 1 and 2.
