Fig 1.
Spectrograms of sweep trains and depiction of training procedures for the counterbalance condition which received progressive training in the ‘low’ frequency range and constant training in the ‘high’ frequency range.
In the low frequency range, Fast/Slow contrasts start with a large difference in Block 1 of training, but progressively become more difficult. In the high frequency range, contrasts start difficult to differentiate and remain difficult throughout training.

Training performance (A’) for the progressive and constant trained frequency ranges.
Error bars show within-subject standard errors of the means [57].
Fig 3.
Test performance (A’) for the progressive and constant trained frequency ranges.
Error bars show within-subject standard errors of the means [57].

Training performance (A’) for the progressive and constant trained frequency ranges.
Error bars show within-subject standard errors of the means [57].
Fig 5.
Test performances (A’) for the progressive (filled squares) and constant (open circles) trained frequency ranges (collapsed across counterbalance conditions) at each level of the repetition factor.
Error bars show within-subject standard errors of the mean [57]. Trained and untrained numbers of repetitions are labeled.
