Motivational state plays a critical role in our ability to learn new motor skills; however, the mechanisms by which motivation influences motor learning are poorly understood. Using a motor learning paradigm in which motivation was varied in a trial-by-trial manner, we found that motivation affects learning by upregulating the rate of the adaptive response, increasing individuals speed of learning. This unveils previously unidentified evidence for a mechanism through which motivation shapes error-based motor learning.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
