The six motor tasks performed during the blind and joint motion sessions by the two participants. Task 1: Participant 1 (P1) and participant 2 (P2) move the right hand in a clockwise circle and the left hand in a counterclockwise circle. Task 2: P1 moves both hands in clockwise circles, P2 moves both hands in counterclockwise circles. Task 3: P1 moves the right hand horizontally and the left hand vertically, P2 moves the right hand vertically and the left hand horizontally. Task 4: same as the task 3, but the participant's moves are reversed. Task 5: same as the task 2, but the participant's moves are reversed. Task 6: same as the task 1, but the participant's moves are reversed. R, right hand; L, left hand. Image reproduced from Llobera et al. (2016).
