Representation of 2D movement trajectories. A) Targets appeared at 7 position angles (θ). An example of reaching movements towards the 7 target locations are represented as red trajectories. B) Example of an angular deviation to the left (α = −20°). Participants should deviate their actual movements (blue) 20° to the right, in order to properly reach the target along the red trajectory given as visual feedback.
