Table 2.

Age, education, and MMSE scores are provided for the whole (N = 38) group (left column). Independent sample Student's t-tests values for these variables are shown for the AVLT (verbal versus visual) input modality groups (center column) and for the ANT (touch versus mouse) response modality groups.
