The meaningful words reported by the healthy people when listening to the Deutsch word illusion were correlated with the normal personality traits. Whether the phenomenon would be more pronounced in patients with personality disorders, especially the cluster A types remains unknown. We therefore invited 11 patients with paranoid, 34 schizoid, and 13 schizotypal personality disorders, and 116 healthy volunteers, to report the Chinese words when they were listening to the Deutsch “High-Low” and “Harvey” word illusions. The paranoid and schizoid personality disorder patients reported more meaningful Chinese words than the healthy volunteers did when they were listening to the “Harvey” word illusion, and more meaningful Chinese words which were corresponding to the DSM-5 pathological personality traits than the healthy volunteers did. The study had demonstrated that when interpreting the illusion stimuli, patients with cluster A personality disorders would mobilize more cognitive processes relating to their personality-specific traits.
