Table 3. Measures of long-term memory on the RAVLT and AFLT, for PD patients and controls, in both experimental sessions.

The mean number of items recalled out of a total of 15 for Lists A and B after delay, along with the mean d' scores, reflecting sensitivity of old-new discriminations for Lists A and B on both the RAVLT and AFLT are presented. Scores for PD patients appear separately for ON and OFF medication sessions. Control participants' data are displayed to correspond to the ON-OFF order of the PD patient to whom they were matched, although they were not treated with dopaminergic medication at any time.
