The time needed to complete each frequently trained sequence, or movement time (MT), decreased over the course of training that was performed inside the scanner during the simultaneous acquisition of BOLD images. The upper image (A) depicts the decreasing group MT pattern, collapsed across the three frequently trained sequences. We combined trials for each participant separately for each scan session into 10 equally sized trial bins (preserving temporal order) and then averaged within each bin. The lower image (B) depicts group MT change during each scan session; each sequence is shown separately. Using an ANOVA, we found a significant effect of session (P < 0.00001) but did not find any significant effect of sequence or interaction. This result confirms that performance was substantially improved over the 3 scan sessions, and that all three frequent sequences were learned equally well. Error bars give the standard error of the mean (SEM).
