“…Supra-spinal control, most probably affected by attention, may in addition add feedforward deterministic variation of the CoP, i.e., the planned state need not be static (Zatsiorsky & Duarte, 2000), which could serve an exploratory role (Carpenter, Murnaghan, & Inglis, 2010). There is evidence that conscious control over a task increases postural sway (Andersson, Hagman, Talianzadeh, Svedberg, & Larsen, 2002;Nafati & Vuillerme, 2011) and that withdrawing attention from the postural task leads to a decrease in postural sway (Andersson et al, 2002;Nafati & Vuillerme, 2011;Riley, Baker, & Schmit, 2003). The contribution of the three controls mechanisms affects the character of the postural sway pattern.…”
