Table 1. Pearson product-moment correlations (r) between neural predictors (Fisher’s z-transformed ROI-to-ROI rs-FC values), neuropsychological predictors (digit span), and behavioral measures related to learning (coordination, transmission, innovation, accuracy) and structural regularization (proximity, melodic regularization).

Notes: Correlation coefficients marked in bold are significant under Bonferroni correction (α=0.05/7 = 0.007; seven is the number of independent tests on each behavioral variable). r = right hemisphere; l = left hemisphere. STG = superior temporal gyrus; HG = Heschl’s gyrus; Tone = measure computed using tone distance; Contour = measure computed using contour distance.
