“…The performance in the in-phase synchronization mode corroborated the findings in the literature (Bingham et al, 1999;Bogaerts et al, 2003;Buekers et al, 2000;Langenberg et al, 1998;Roerdink, Peper, & Beek, 2005;Ryu & Buchanan, 2009;Swinnen, et al, 1998;Wilson, Collins, & Bingham, 2005a, 2005b. The spatial accuracy of the arm movements was significantly lower in the 50% feedback condition in which the spatial incompatibility (i.e., perception of the arm in a position that is incompatible with the proprioceptive information of the muscle afferents) between the target signal and the temporally shifted visual feedback of the actual arm movement was maximal Poulton, 1974).…”
