Summary

Confabulators consistently generate false memories without intention to deceive and with great feeling of rightness. However, there is currently no known effective treatment for them. In order to fill this gap, the aim of this trial was to design a neuropsychological treatment based on the current theoretical models and test it experimentally in two groups of confabulators: experimental vs. control. The treatment consisted of some brief material that patients had to learn and recall at both immediate and delayed moments. After both recollections, patients were given feedback about their performance (errors and correct responses). Pre-treatment and post-treatment baselines were administered. Confabulators in the control group performed the baselines without treatment, and were then offered the treatment after the second baseline.

BEHAVIORAL

Neuropsychological treatment

Participants had to learn some brief material (words, faces, pictures, news), after which they were asked for an immediate and a delayed recall. After both recalls, participants were confronted with feedback about correct responses, non-responses and errors (i.e., confabulations and errors of attribution). This type of feedback worked on: 1) selective attention during the learning phase, training patients to focus on the relevant details of the stimuli; 2) monitoring processes during the retrieval phase, reinforcing the strategic search and training patients to inhibit traces that were irrelevant; and 3) memory control processes after the retrieval phase. The treatment consisted of 9 sessions and lasted for 3 weeks and the participants performed a baseline before and after treatment.
