a Time required to repeat 5 times one of the two syllables for the imagery (magenta) and speaking (yellow) modalities in the group with continuous (lighter colors) and discontinuous feedback (darker colors) over the 5 training days. b Deviation from isochrony index reflecting the ratio between the average duration of the imagined vs spoken syllable repetition, in the group that trained with continuous (green) and discontinuous (purple) feedback. Error bars indicate the standard error of the mean.
