( A ): The visual encoding strategy suggests that the brain evaluates the potential targets based on the decision variables (e.g., expected reward and effort cost) and generates an averaged visual-spatial target location q goal ( x t ) (right panel). The “visual” target is computed as the weighted average of the two potential target locations ( q 1 and q 2 ). The reach trajectory (gray continuous trace on the right panel) that aims towards the visual target location can be simulated using an optimal waypoint (green points) planning algorithm. Once the actual goal is revealed, the movement is corrected in-flight to the actual target location. Therefore, the reach trajectory consists of an initial phase towards the visual target location (gray trace) and a final phase towards the correct target location (black discontinuous trace). ( B ): The alternative hypothesis suggests that the brain plans simultaneously single-target actions (i.e., control policies) π 1 and π 2 that compete for selection and uses the decision variables to bias the action competition. The weighted average of the individuals planned single-target actions produces the motor action π mix that generates the reaching movement (black discontinuous trace right panel). |
