Protocol for Experiment 2. a Hand configurations in the Experiment 2 and examples of the real-time visual feedback provided during each trial. The height of the blue bar displayed on the screen was proportional to the sum of the force applied by the two hands. The black line indicated the desired target force that had to be reached with equal force contribution of the two hands. b Visual description of the two target forces proposed during the experiment
