“…In particular, it seems that the guidance hypothesis proposing that concurrent or frequent feedback is detrimental for motor learning due to emerging dependency on the feedback (Salmoni, 1984;Schmidt, 1991;Schmidt, Young, Swinnen, & Shapiro, 1989), holds true for simple tasks (Schmidt & Wulf, 1997;Van der Linden, Cauraugh, & Greene, 1993;Winstein et al, 1996), but not for complex tasks (Marschall, Bund, & Wiemeyer, 2007;Swinnen, Lee, Verschueren, Serrien, & Bogaerds, 1997;Wulf, Shea, & Matschiner, 1998). In an early stage of complex task learning, concurrent feedback may accelerate learning by mediating a general idea of the movement (Huegel & O'Malley, 2010;Liebermann et al, 2002) and by preventing cognitive overload (Wulf & Shea, 2002). Indeed, concurrent visual feedback has facilitated learning of different complex tasks (Kovacs & Shea, 2011;Snodgrass, Rivett, Robertson, & Stojanovski, 2010;Swinnen et al, 1997;Todorov, Shadmehr, & Bizzi, 1997;Wishart, Lee, Cunningham, & Murdoch, 2002;Wulf, Hörger, & Shea, 1999).…”
