Figure 1.

Changes in mean absolute error (AE) with respect to the required CDR across scanning (A) and training (B) sessions, respectively (see Results). A, Error scores are depicted across the three scanning sessions for bimanual as well as unimanual (control) conditions. B, Each training day is represented by the averaged absolute error of the final five bimanual trials as performed under single-task (bimanual) and dual-task (bimanual + two-back) conditions. Scanning occurred before day 1, after day 4 (first week of training), and after day 8 (second week of training). For additional details, see Materials and Methods.
