“…Skill learning requires a much more flexible system, one that can exploit multiple sources of information and heuristics to create novel movement patterns (Yang et al, 2021). These capabilities draw on multiple learning processes that use a broad range of error and reinforcement signals (Galea et al, 2011;Shmuelof et al, 2012;Tsay, Kim, Saxena, et al, 2021) that may be attuned to different contexts (Avraham, Taylor, et al, 2020;Heald et al, 2021). While we anticipate that these processes are sensitive to multimodal inputs, it will be useful to revisit these models with an eye on the relevance of proprioception.…”
