Variability in joystick input. (A) Representative joystick inputs in blocks 1 and 8 during the training phase. The black dots represent joystick inputs. (B): Task-irrelevant variability across blocks. Thick lines indicate the mean across participants. Error bars indicate mean ± standard error across participants. The red and blue lines represent the small and wide target conditions, respectively. (C) Box plot of task-irrelevant variability in the last block of the training phase. Circular dots indicate the task-irrelevant variability of each participant. (D) Relationship between task-irrelevant variability in the last block of the training phase and the success rate in the first block of the test phase. The red and blue dots represent the small and wide target conditions, respectively.
