Performance on the final day (day 4) for trained and untrained stimuli. A. Mean response accuracy on day 4 for the trained musical-interval comparison task with the trained pure-tone (solid bars) and untrained triangle-tone (striped bars) stimuli for each of 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). The dotted line indicates chance performance. B. Individual response accuracy on day 4 for pure-tone (x-axis) and triangle-tone (y-axis) stimuli, 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).
