Setup and procedure for the main experiment (left, above view; right, side view). t1, Proprioceptive target (left thumb) was presented at one of three possible locations (cross, 0°; circle, 5° left; diamond, 5° right) for 1 s, while the head was directed toward the target (dashed lines). t2, After the left-target hand was moved back to the starting point, the speaker indicated the direction that subjects had to move their head, by 10° or 15° leftwards or rightwards. With the head in this direction, participants used their outstretched right index finger to reach to the remembered proprioceptive target.
