Receding horizon and infinite horizon model simulations. A, Simulated velocity profiles of receding horizon (dashed) and infinite horizon (dot-dashed) models. Both models naturally produce positively skewed velocity profiles, more closely resembling early-peak velocity, rather than the baseline condition. B, Mean experimental movement durations (bar chart) compared with the receding and infinite horizon model predictions. Both models accurately simulate the variations in the reach durations with perturbation location. Baseline (C) and early-peak velocity condition (D) simulations for receding horizon, infinite horizon and time-to-target (dot-solid lines) models, compared with the experimental data. Only the time-to-target model predicts different visuomotor feedback response intensities for different perturbation onset locations, while receding and infinite horizon models predict constant intensities. Note that models were not fit to match the intensities, only to qualitatively demonstrate the behavior.
