The absolute (top rows) and relative (bottom rows) mean percent correct (PC) scores of the baseline measurements before and after training of the SG and NG (left and middle columns), and overall improvement taken from Fig. 1 (right column).

The CG received no training and were only tested with the baseline measurements, to see the potential learning effects due to the exposure to testing paradigm only, in the lack of a targeted training. ‘S’ and ‘N’ refer to testing conditions with interrupted sentences with silent intervals or with filler noise, respectively.
