Nevertheless, recent studies have called into question whether online feedback is, in fact, fundamental to the learning process (Wierinck, Puttemans, & van Steenberghe, 2006;Wu et al, 2011). Studies showing that (1) patients with sensory impairments do not show difficulty learning new motor skills (Missaoui & Thoumie, 2013;Riva et al, 2014); (2) untrained segments are able to improve their performance on a new motor skill after the training of a distinct body segment, therefore, without online sensory feedback (Harley & Prilutsky, 2012), and (3) learning by mental practice (Gentili, Papaxanthis, & Pozzo, 2006;Schuster et al, 2011), i.e.…”
