title: Confabulations: a conceptual history.
abstract: Confabulations are inaccurate or false narratives purporting to convey information about world or self. It is the received view that they are uttered by subjects intent on "covering up" for a putative memory deficit. The epidemiology of confabulations is unknown. Speculated causes include amnesia, embarrassment, "frontal lobe" damage, a subtype of "personality", a dream-like event, and a disturbance of the self. Historical analysis shows that "confabulation" was constructed at the turn of the century as part of a network of concepts (e.g. delusion, fixed idea, etc.) meant to capture narratives with dubious content. This paper deals with the history of the construction of the word and concept of confabulation and with earlier recognitions of the behaviours that serve as their referent and puts forward a model based on historical data. Two phenomena are included under "confabulation": "untrue" utterances by subjects with memory impairment and "fantastic" utterances marshalled with conviction by subjects suffering from psychoses and no memory deficit. Under different disguises, the "covering up" or "gap filling" hypothesis is still going strong. Although superficially plausible, it poses problems in regards to the issue of "awareness of purpose": if full awareness is presumed then the semantics of the concept of "purpose" is severely stretched and confabulations cannot be differentiated from delusions.
