A popular model of human sensorimotor learning suggests that a fast process and a slow process work in parallel to produce the canonical learning curve . Recent evidence supports the subdivision of sensorimotor learning into explicit and implicit processes that simultaneously subserve task performance . We set out to test whether these two accounts of learning processes are homologous. Using a recently developed method to assay explicit and implicit learning directly in a sensorimotor task, along with a computational modeling analysis, we show that the fast process closely resembles explicit learning and the slow process approximates implicit learning. In addition, we provide evidence for a subdivision of the slow/implicit process into distinct manifestations of motor memory. We conclude that the two-state model of motor learning is a close approximation of sensorimotor learning, but it is unable to describe …
