  1. Except for the PTONI age-normed standard scores (which are the z-scored standard scores), the raw scores of all other variables were z-scored, regressed on age, and the resulting residuals were z-scored once again, and these z-scored, age-regressed residuals were used in the correlation matrix. Values are correlation r values for each pair of variables. Missing values were excluded in a pair-wise manner. SPELT-3 = Structured Photographic Expressive Language Test; BBA = Beat-Based Advantage; PTONI = Primary Measure of Non-Verbal IQ; KABC = Kaufman Assessment Battery for Children; SES = Socioeconomic Status; MES = Musical Experience Score.
  2. *indicates p < 0.05, and **indicates p < 0.001.
