In order, means and standard errors of the starting age (in years) of musical training and practice, weekly hours spent in practicing and in listening to music, years of musical practice. p-Value, standardized Beta, 95% confidence interval (CI; lower bound, LB, and upper bound, UB) and partial correlation for each variable as reported from a regression model are also provided. Significant statistical values are reported in bold.
