Correlations between psychoacoustic measures and Principal Component 3 fluency.
| Psychoacoustic measure | Spearman correlation with PC3 | |
|---|---|---|
| Spearman’s rho | P value | |
| Pitch basic change detection threshold (semitones) | − 0.21 | 0.21 |
| Pitch detection of local change (% correct) | 0.43 | 0.04 |
| Pitch detection of global change (% correct) | 0.63 | 0.003* |
| Rhythm single time interval discrimination threshold (%) | − 0.64 | 0.004* |
| Rhythm isochrony deviation detection threshold (%) | − 0.20 | 0.24 |
| Rhythm metrical pattern discrimination threshold (%) | − 0.72 | 0.001* |
| Dynamic modulation detection threshold (%) | − 0.15 | 0.29 |
‘P value’ corresponds to uncorrected one-sided p-values from Spearman correlations comparing psychoacoustic scores with PC3 fluency scores in the post-stroke aphasia subgroup. * indicates the p-value is significant at the Bonferroni corrected significance threshold of p < 0.007 (corrected for 7 comparisons). ‘PC’ = Principal Component.
