fMRI Investigation of Cortical and Subcortical Networks in the Learning of Abstract and Effector-Specific Representations of Motor Sequences

completion times were similar in the normal settings (NormalM and NormalV),
they were much shorter for the motor than for the visual setting.

Results from Repeated Measures ANOVA analysis for the Accuracy and Set
completion times are tabulated in Table S1. To investigate the slower
performance in visual setting as compared to the motor setting, we performed
additional analysis of set completion times in the late stage. We tested for the
correlation between the sequence structures of the rotated and corresponding
normal settings. For this, we averaged set completion times for each of the six
sets for successfully completed hypersets in the late stage of each
experiment. The correlations reported in Table S2 clearly point out the
similarity of the motor sequence structure used by the subjects between the
motor and normalm settings (11 out of 14 measurements). In contrast, a lack
of correlation was observed between the visual and normalv settings (13 out
of 14 measurements). This result points out that the sequence structures
acquired in the visual and normalv settings are different.
