On the money and right on target: How robust are reward and task success effects on implicit motor adaptation?

We are motivated to perform well and earn rewards, but do rewards help maintain motor skill calibration? Here, we observed that implicit motor adaptation is not sensitive to abstract signals of reward, such as money or auditory cues related to performance, although adaptation was influenced by visual signals of task success like hitting a target. These data suggest that the implicit motor system may be primarily concerned with performance metrics rather than rewards.
