Our tal oscillatory smooth pursuit, it may indicate interference present study adopted a “biofeedback” approach, in which between oculomotor and sway control, potentially due to an the perceptual difficulty in a visual signal detection task efferent oculomotor signal [1 ]. In specific contexts, however, (VSDT) was coupled (implicit feedback coupling, IFC) to body sway reduction has also been reported during smooth either body sway directly or to the contact force during fin- pursuit . Riccio and Stoffregen [3 ] argued that the pos- gertip light touch. In both situations, we expected that body tural control system also takes into account
