Table 4.

Proportion of explained variance (R2) between neuropsychological test scores and individual model parameters or response type frequencies. The degrees of freedom are indicated as subscripts in the column headings. The strongest parameter association for each test score is marked in gray, as well as any response type frequency associations that were stronger than the parameter associations.
