Performance on the final day (day 4) for trained and untrained tasks. A. Mean response accuracy on day 4 for the untrained musical-interval comparison task (bars) for each of the four training regimens (shades) as estimated by a single-level regression, with standard errors from the regression (error bars) and individual data (gray circles; raw data). B. Individual response accuracy on day 4 for the trained musical-interval comparison task (x-axis) and the untrained comparison task (y-axis) for each of the four training regimens (symbols; raw data), with means and standard errors as estimated by a single-level regression (line and gray region). C. Individual response accuracy on day 4 for the trained musical-interval comparison task (x-axis) and the untrained identification task (y-axis) for each interval (symbols), with means and standard errors as estimated by a single-level regression (lines and gray regions).
