Experiment 1: Selected subject performance in the stabilization task (λ = 1.0). a Hand trajectory showing drift over time (line shading). Drift was modeled from t = 5 s to the end of the trial at t = 60 s. b Time course of the x (black) and y (blue) components of the endpoint trajectory from t = 5 s to t = 60 s. Scale bars: as in panel c. c Time course of the x (black) and y (blue) components of the endpoint trajectory residuals after removal of the drift, from t = 5 s to t = 60 s
