When the experiment began, visual instructions were provided on the monitor by displaying a black cross sign on a gray background. The participants stared at the visual instructions for 4 s while resting. After resting, a visual cue was displayed on the monitor with a text sign for 3 s, following which the participants began preparing to perform the real-movement or MI tasks according to the visual cue (see Fig. 2). Upon changing the visual cue to a text sign reading “Movement Execution” and “Movement Imagery,” the participants performed the corresponding tasks during 4 s. During the real-move…
