EFFECTS OF SURFACE-FEATURES ON WORD-FRAGMENT COMPLETION IN AMNESIC SUBJECTS

Patients with amnesia resulting from alcoholic Korsakoff syndrome and elderly control patients studied a list of words in two typographies (typed and handwritten) and then received a word-fragment completion test (e.g., -ys-e-y for mystery) in which the test cues also varied in typography. Unlike the elderly control patients, the amnesic patients did not show greater priming effect when the typography at test matched that at study. The amount of typography-dependent priming was positively correlated with the score on the Wechsler Memory Scale. These results suggest that the effects of typography change on repetition priming in word-fragment completion reflect explicit recollection, and that the representation that supports repetition priming effects observed with amnesic subjects in the word-fragment completion task does not code typography information.
