“…The finding of partially intact recognition on the low-criterion test is consistent with dual process theories (see, e.g., Mandler, 1980; see also Atkinson & Juola, 1973;Jacoby & Dallas, 1981), which hold that recognition can be mediated by the same activation-based process that underlies priming. Also in line with such theories, previous studies have shown that amnesic patients often show above-chance recognition, despite very poor recall (e.g., Hirst et al, 1986;Hirst & Volpe, 1982;Huppert & Piercy, 1977; but see Haist et al, 1992).2 A study using event-related potential methodology, moreover, provided evidence that the familiarity component of recognition is intact in amnesic patients, despite little evidence of retrieval (Smith & Halgren, 1989). Support for a dualprocess model is also available from numerous studies of normal subjects (e.g., Dorfman & Mandler, 1994;Jacoby & Dallas, 198!…”

Priming and recognition in ECT-induced amnesia

and JOHN MISIASZEK University ofArizona CoUege ofMedicine, Tucson, ArizonaPriming and recognition were tested in patients receiving electroconvulsive therapy (ECT) for treatment of a psychiatric disorder. Patients studied a list of words just prior to ECT and then received memory tests for those words after recovering from ECT. Stem-cued recall was poor (retrograde amnesia), but priming on word-stem completion was preserved. Recognition was poor on a "high-criterion" test requiring a retrieval-based judgment but partially intact on a "low-criterion" test requiring a familiarity-based judgment. The results support the familiarity-retrieval distinction in two-component theories of recognition and suggest that signal detection measures of sensitivity are not wholly independent ofresponse criteria.

“…For example, amnesic patients often exhibit partially intact recognition, despite showing very poor recall (e.g., Hirst & Volpe, 1982;Hirst et aI., 1986;Huppert & Piercy, 1977; but see Haist, Shimamura, & Squire, 1992, for a different view). Moreover, the rate ofdecay in recognition mirrors that of…”

“…Moreover, it was also predicted that additional study time (5 s) would lift Korsakoff patients' performance up to the level of controls in the standard 2-s condition (cf. Huppert & Piercy, 1977;Van Damme & dЈYdewalle, 2008), whereas the patients' performance in the standard condition would be similar to controls' performance in the 250-ms condition. The latter prediction was based on studies showing that amnesic patients are comparable to healthy individuals with weak memory (e.g., after inadequate study time, Meudell & Mayes, 1984; or after prolonged retention intervals, Woods & Piercy, 1974).…”

Recent studies with the Deese/Roediger-McDermott (Deese 1959;Roediger & McDermott, 1995) paradigm have revealed that amnesic patients do not only show impaired veridical memory, but also diminished false memory for semantically related lure words. Due to the typically used explicit retrieval instructions, however, this finding may reflect problems at encoding, at recollection, or both. Therefore, the present experiments examined implicit as well as explicit false memory in patients suffering from Korsakoff's syndrome and controls. In Experiment 1, encoding instructions either focused on remembering individual list words, or on discovering semantic relationships among the words. In Experiment 2, different presentation durations were used. Results emphasize the distinction between automatic and intentional retrieval: Korsakoff patients' veridical and false memory scores were diminished when explicit recollection was required, but not when memory was tested implicitly. Encoding manipulations only significantly affected veridical memory: Priming was reduced with thematic encoding, and explicit retrieval was facilitated when given more study time.

“…In order to ensure this, studies have typically allowed amnesic subjects a longer exposure time to the target stimulus [12,17,21,31]. While this procedure has been valuable it can create potential problems.…”
