Forms of confabulation: dissociations and associations.

摘要: Confabulation denotes the emergence of memories experiences and events which never took place. Whether there are distinct forms with mechanisms is still debated. In this study, we explored 4 confabulation their in 29 amnesic patients. Patients performed tests explicit memory, executive functions, two test orbitofrontal reality filtering (memory selection extinction capacity a reversal learning task) previously shown to be strongly associated confabulations that patients act upon disorientation. Results indicated following associations: (1) Intrusions verbal memory (simple provoked confabulations) dissociated from all other were not any specific cognitive measure. (2) Momentary confabulations, defined as confabulatory responses questions measured questionnaire, impaired mental flexibility, tendency fill gaps one measure filtering. therefore, may emanate diverse causes. (3) Behaviourally spontaneous confabulation, characterized by disorientation, was failure tasks. seen instance momentary mechanism. (4) A patient producing fantastic nonsensical, illogical content had wide-spread dysfunction failed The results support presence truly or partially dissociable types different mechanisms.
