A functional synergistic model to explain postural control during precise visual tasks

摘要: In everyday life, individuals sometimes have to perform precise, or challenging, visual tasks in upright standing. Upright, one problem precise saccades and fixations is that the body oscillates continuously a mainly unpredictable way. Current cognitive models assume central nervous system should divide its attention these 'dual tasks' because of limited attentional resources (keeping balance performing task). The with concept duality (need to) succeed not be more unstable inefficient - division tasks. our opinion, work adaptively way enables success Hence, instead assuming 'duality' processes, we suggest i) 'synergy' unification between postural processes may required Success would also require ii) synergy based on two feedforward process being leader; iii) reduce their sway facilitate successful synergies; iiii) additional link processes. We discuss some literature findings consistent assumptions summarize recent validation synergistic model. summary, both could complementary present manuscript shows how they included higher-order, directional, model control.
