Effects of Time-Compressed Speech Training on Multiple Functional and Structural Neural Mechanisms Involving the Left Superior Temporal Gyrus

Table 1

The mean ± SD difficulty level of the most difficult performances of all subjects (the highest difficulty level at which the subjects still achieved at least five correct answers to the 10 problems in each set of auditory stimuli in training tasks among the first three and last three training sessions).

	First three sessions	Last three sessions
Training with TCSSL (times faster than the original speed)	2.09 ± 0.38	2.97 ± 0.55
Active control training (semitones (#) higher than the original pitch)	12.72 ± 2.49	19.36 ± 5.32
