“…Confabulations can be defined as unintentionally produced actions and statements that are incongruent with the present situation and are frequently observed in amnesic patients (Cooper, Shanks, & Venneri, 2006;Dalla Barba, 1993). Confabulation has also been referred to as "honest lying," since people who confabulate are not aware of the falseness of their statements (Moscovitch, 1995).…”

“…However, provoked confabulations have mostly been measured by the number of intrusions on word-list learning tasks. Examination of the relation between provoked confabulation and measures of memory functioning may be informative when using measures better suited to examine provoked confabulation, such as the Provoked Confabulation Test (Cooper et al, 2006) or the Nijmegen-Venray Confabulation List-20 (NVCL-20; Rensen et al, 2015).…”

“…Especially damage to the ventromedial and/or oribitofrontal regions might result in spontaneous confabulation behavior (for a review, see Kopelman, 2015). Although spontaneous confabulations have been linked to frontal damage and executive dysfunction, several studies demonstrated that there was no relation between performance on executive measures and confabulation behavior (Cooper et al, 2006;Rensen et al, 2015;Schnider & Ptak, 1999;Schnider et al, 1996). The relationship between spontaneous confabulation and executive dysfunction remains unclear and has never been explored in large sample sizes.…”

“…Therefore, the clinician should focus on the production of this type of intrusion, rather than the total number of intrusions, when one wants to screen for confabulation tendencies. Moreover, when a clinician wants to quantify confabulation behavior, we suggest the use of instruments such as the Provoked Confabulation Test (Cooper et al, 2006) and the NVCL-20 (Rensen et al, 2015), which are designed to serve this purpose. As for research on confabulations, our results indicate that the total number of intrusions on memory tests is different from clinical confabulations, and conclusions based on the examination of total intrusions should not be extended to (provoked) confabulations.…”

Introduction: Intrusions on verbal memory tests have been used as an index for clinical confabulation. Severe memory impairments in combination with executive dysfunction have been suggested to be the underlying mechanism of confabulation, but to date, this relation is unclear. The aim of this study was (a) to examine the relation between (different types of) intrusions and confabulations in a large sample of confabulating patients with Korsakoff's syndrome (KS) and (b) to investigate whether different measures of executive functioning and memory performance are related to provoked and spontaneous confabulation. Method: The Dutch version of the California Verbal Learning Test (CVLT) and various executive function and memory tests were administered to a group of 51 confabulating patients with KS. Professional caregivers rated the severity of provoked and spontaneous confabulation behavior of the patients using the Nijmegen-Venray Confabulation List-20 (NVCL-20). Results: The total number of intrusions on the CVLT was not related to either provoked or spontaneous confabulation scores. None of the CVLT intrusion scores correlated significantly with any of the confabulation scores, but we did find small-to-medium, positive correlations between unrelated intrusions and both provoked confabulations and spontaneous confabulation. Provoked confabulation behavior was associated with executive dysfunction and poorer memory performances. Spontaneous confabulation was not related to performance on measures of executive function and memory. Conclusions: The total number of intrusions on verbal memory tests and clinical confabulations appear to be different phenomena. Only unrelated intrusions produced on the CVLT might possibly be related to confabulations. The production of provoked, but not spontaneous, confabulation is associated with executive dysfunction and memory deficits.

“…Spontaneous confabulation is believed to be an interaction between frontal lobe pathology and organic amnesia [9]. Provoked confabulations occur in response to a prompt, or an external cue, and may represent a normal response to a faulty memory [10]. These types of confabulation can become apparent during memory tests, interviews, or under cross-examination.…”

Confabulation can be defined as the unintentional creation of a false or inaccurate memory to compensate for memory gaps or deficits. Although some similarities may exist, the phenomenon of confabulation is distinguishable from other issues like suggestibility, malingering, and delusions. The possibility of confabulation is particularly pernicious in criminal justice settings. Here, self-reported memories play an integral role in the confessions and testimony of suspects, defendants, victims, and eyewitnesses. To raise awareness of this possibility, and protect against its consequences, this article reviews warning signs and risk factors for confabulation, tips on how to communicate with and treat individuals who may be confabulating, and recent research in the area of confabulation. In short, this serves as an introduction to confabulation for legal professionals.
