Abstract
This study examined whether verbal and visual memory impairments in mu ltiple sclerosis (MS) are attributable to deficits in acquisition, sto rage, or retrieval. Volunteers with MS (n = 40) and healthy controls ( n = 20) rehearsed a word list and a checkerboard pattern using a selec tive reminding procedure until two consecutive error-free trials were attained. Recall and recognition were assessed after 30 min and 90 min (and 1 week for verbal material) delays. The MS group required signif icantly more trials to attain criterion on both learning tests. Once e quated for acquisition, both groups performed similarly on verbal reca ll and recognition. However the MS group performed significantly worse on measures of visual recall and recognition. The results suggest tha t the verbal memory impairment in MS is due to deficient acquisition, while the visual memory impairment in MS is attributable to deficits i n acquisition and storage.
