Figure 2. Correlation of a) MD-weighted lesion volume, and b) language-weighted lesion volume with verbal fluency scores.

Figure 2

Verbal fluency residuals are standardized residuals in the regression of Cattell Culture Fair scores against verbal fluency scores (a more negative score indicates poorer performance). Point colour indicates lesion anatomy: frontal (red), parietal (blue), occipitotemporal (green), or parietal and occipitotemporal (black). r is Pearson’s correlation coefficient, P is the corresponding one-tailed P-value of the correlation. r, P, and fit lines are shown for the whole group (N=79). After partialling out variance attributable to IQ, verbal fluency is predicted by the extent to which lesions affect the language, but not the MD, system.
