Patient demographic and lesion data.

Neuropsychological results before the treatment.

<p>Mean scores and standard deviations (in parentheses) for each test in both control (pre-waiting) and experimental (pre-treatment) groups, as well as the results of the comparison between them. The scores of the control group are divided into two subgroups ('pure' and 'mixed').</p

Scores before and after the treatment.

<p>Mean scores and standard deviations (sd) for confabulations, correct responses, and non-responses and for both correct responses and errors in source attribution, organized by group and time-point measure. Note that the post-treatment measurement in the control group was performed by 5 patients. Note also that the direct scores of a single patient are shown in the post-treatment follow-up measure after both 9 and 18 months.</p

Main results for both the experimental (left) and control (right) groups.

<p>When we compared the pre-treatment and post-treatment measures, the experimental group showed a significant reduction in confabulations and an increase in correct responses, but non-responses remained the same. However, when the pre-waiting and post-waiting measures were compared, confabulations not only did not decrease but even significantly increased; non-responses decreased, while correct responses remained the same.</p

Stimuli used in the treatment.

Experiment 2: Mean Reaction Time (in ms) and percentage errors (in Parentheses) as a function of display type, cueing, SOA, and spatial Stroop.
