Indexes derived from mouse velocity profiles recorded during Experiment 1.

<p>Each data point represents the mean value (± SEM) computed for each experimental condition among subjects belonging to either Group 1 (right column) or Group 2 (left column). Open circles, Visible session; Filled back triangles, Masked session. Vertical dashed grey lines separate experimental conditions with different laws of motion (1–6: 0 g; 7–12: 1 g; 13–18: 2 g). A–B. Movement onset. C–D. Latency of the maximal velocity peak. E–F. Maximal mouse velocity. G–H. Movement duration.
