The implicit memory ability of a patient with amnesia due to encephalitis

A Twenty-Year Follow-up Case Study of an Office Worker Who Returned to Work despite Serious Memory Disorder Caused by Herpes Encephalitis

“…Many researchers claimed that priming effects on declarative memory and amnesia is more affected than Korsakov's syndrome [13,14] and this case of amnesia totally supports their hypothesis. Hamann and Squire (1997) [2] claimed that separating priming memory from declarative memory is difficult; however, if a clear distinction exists between recent memory that is supported by priming memory and the one that is not, as this case revealed, it indirectly portrays that the priming memory is actually functioning.…”

Normal acquisition of novel verbal information in amnesia.

“…Other studies have found that amnesic patients do not exhibit priming of novel information based on unrelated word pairs (Cermak et al, 1988; Mayes & Gooding, 1989; Shimamura & Squire, 1989). However, normal subjects do show priming of new associations in the same paradigm (Graf & Schacter, 1985).…”

Separating consciously controlled and automatic influences in memory for new associations.

“…Thus, the present results point to a potential resolution of some discrepancies between the literature on single-word repetition priming and the literature on associative repetition priming. More specifically, in contrast to single-word repetition priming, the associative repetition effect was not produced in normal participants who were "unaware" of the test manipulation (Bowers & Schacter, 1990; but see Howard et al, 1991), in normal participants under shallow encoding (Graf & Schacter, 1985; but see Micco & Masson, 1991), or in densely amnesic patients (Cermak, Blackford, et al, 1988;Mayes & Gooding, 1989;Schacter & Graf, 1986b;Shimamura & Squire, 1989). If, indeed, the associative repetition effect under elaborative encoding is largely mediated by consciously controlled retrieval processes, then these differences are no longer surprising.…”
