Multiple regression on the rapid visual information processing (RVP) measure d′ with age, and fractional anisotropy (FA) of right and left superior longitudinal fasciculus (SLF), and global white matter (WM). Significant associations are printed italic, with those related to FA‐measures additionally printed in bold.
