Experiment design and behavioral performance of all participants. (A) In the localizer session, participants move or stop their right fingers freely in response to the message displayed on the screen. The first principal components were calculated from the random finger movement by PCA and used as a finger-to-cursor movement mapping in the main session. (B) In the main session, a target appeared as a gray cell in the same order for each block, and participants were instructed to reach a target by moving their fingers. A target turned red when reached by a cursor, which was visible in odd-numbered blocks (cursor-on condition) but not in the even-numbered blocks. Target locations were altered in the test condition where a cursor was always visible. (C) Block-by-block group performance. Participants improved performance across alternating "cursor-on" (blue) and "cursor-off" (green) learning blocks and continued in the test blocks (yellow). Error bars indicate SEM.
