Figure 5.

Image-specific correlation between MVPA decision variables and behavioral confidence ratings (averaged across observers for each individual image). A, Correlation coefficients between the behavioral confidence ratings versus the classifier decision variables computed from fMRI activity of each ROI for each individual image averaged across 12 observers (expected maximum 12 trials). B, The two-variable scatter plot of the behavioral confidence ratings versus the classifier decision variables computed from fMRI response in IPS for each individual image. The correlation coefficient between the two variables was 0.53, with a confidence interval of [0.46 0.59].
