“…Results confirmed the expectation of diminished recognition of both studied words and critical lures in Korsakoff patients. Implicit memory for both types of items was normal as compared to controls (cf Van Damme & d'Ydewalle, 2009a;Van Damme & d'Ydewalle, 2010). Delayed gist recognition did not show an influence of encoding context: Korsakoff patients' performance was consistently lower than controls', regardless of whether they had studied stories or lists.…”

In the DRM paradigm, participants are presented with, and their memory is tested for, lists of words that are associatively related to a non-presented lure word. Recent studies have revealed that amnesic patients show heightened immediate, but diminished delayed false recognition of such related lure words as compared to healthy controls. These findings may reflect deficient encoding, retrieval, or both. In two experiments, the importance of encoding factors was evaluated by investigating whether story contexts would increase delayed lure recognition, and whether personally-relevant content would decrease immediate lure recognition in Korsakoff patients. With delayed testing, patients' lure recognition was consistently lower than controls'. With immediate testing, lure recognition was less frequent for personally-relevant than for neutral materials. However, as opposed to controls, Korsakoff patients did not show a difference in source memory, but merely a change in response bias. Results point to the conclusion that deficient explicit recollection is the main factor determining the difference in false recognition between amnesic patients and controls.

“…In order to investigate the association between confabulation and DRM false memory, a linear regression analysis was carried out on Korsakoff patients' performance in the DRM paradigm using confabulation as a quantitative predictor. To control for the fact that two different encoding durations were used in the DRM experiment (Van Damme & d'Ydewalle, 2010, Exp. 1), the encoding condition was also included in the analysis as a qualitative predictor.…”

“…Since Ciaramelli et al obtained a clear association between confabulation and immediate false recognition, but less clear results for delayed recognition, the present study focused on the latter. DRM data were taken from Van Damme and d'Ydewalle (2010, Exp. 1).…”

“…Moreover, confabulating patients are characterized by deficient strategic retrieval and defective monitoring. In Van Damme and d'Ydewalle (2010), ‘meaning retrieval instructions’ were used, asking participants to endorse any item that shared the meaning of the studied lists, irrespective of whether or not they had actually seen it before. This was done to allow for a direct comparison of Korsakoff patients' and controls' explicit memory for the gist of the lists, without having to take into account possible inhibition of false memories by controls (cf.…”

The present study focuses on both the clinical symptom of confabulation and experimentally induced false memories in patients suffering from Korsakoff's syndrome. Despite the vast amount of case studies of confabulating patients and studies investigating false memories in the Deese-Roediger-McDermott (DRM) paradigm, the natureo fK orsakoff patients' confabulatoryb ehaviour and its association with DRM false memories have been rarely examined. Hence,t he first aim of the present study was to evaluate confabulatoryresponses in alarge sample of chronic Korsakoff patients and matched controls by means of the Dalla Barba Confabulation Battery. Second, the association between (provoked) confabulation and the patients' DRM false recognition performance was investigated. Korsakoff patients mainly confabulated in response to questions about episodic memorya nd questions to which the answerw as unknown. Ap ositive association was obtained between confabulation and the tendency to accept unstudied distractor words as being old in the DRM paradigm. On the other hand, therewas anegative association between confabulation and false recognition of critical lures. The latter could be attributed to the importance of strategic retrieval at delayedm emorytesting.Korsakoff's syndrome typicallyd evelops following years of chronic alcohola buse and nutritional thiamine deficiency (e.g., Homewood &B ond, 1999).T he most cardinal featureo ft he syndrome is undoubtedly the disproportionate impairment of memory relative to other aspects of cognitive functioning (Butters&Cermak,1 980;Parkin & Leng, 1993). Another salient symptom, however,i st he patients't endencyt o confabulate (e.g., Dalla Barba, Cipolotti, &D enes,1 990; Kessels, Kortrijk, Wester,& Nys, 2008;Kopelman, 1995;Talland, 1965). As stated by Dalla Barba (1993a, p. 2), confabulation is 'that particular symptom, frequently observedi na mnesic patients unaware of their memorydeficit, which consists of both actions and verbalstatements that are unintentionally incongruous to the patients'h istory, background, and present situation'. More specifically,c onfabulations can be defined as erroneous memories, either falsei nt hemselves or resulting from the inappropriater etrieval or misinterpretation of 'true' memories (Kopelman, Guinan, &L ewis, 1995; form ore definitions, see Schnider,2008). Ad istinction often made is the one between 'spontaneous'c onfabulation and 'provoked' or 'momentary' confabulation (Kopelman,1 987; see also Berlyne, 1972; Schnider,2008).Whereas the former refers to the unprovoked production of erroneous, incoherent, and often implausible memories, the latter refers to intrusions or distortions of memory in responset oac hallenge,s uch as questions or am emoryt est. As this secondt ype of confabulation is considered coherent and internallyc onsistent, and mainly comprises true memoriesb eing displaced in time and context, it closely resembles the type of memoryd istortion we all sometimes produce. Both involve reconstructive processes and the modification or ...
