The Effect of Conditional Probability of Chord Progression on Brain Response: An MEG Study
Figure 4
Mean correct rates on the behavioral test and correlation with normalized EANm activities.
A. Mean correct rates by types (tonic, submediant, supertonic) and groups. Error bars indicate the standard errors of the means. The dotted horizontal line indicates the chance level (1/3). B. Scatter plot of normalized EANm activities vs. correct rates for submediants in non-musicians for the time-window of 100–170 ms as EANm1. A linear regression line is indicated (red) with the Pearson correlation coefficient (r) noted. C. Scatter plot for the time-window of 180–250 ms as EANm2.
