dc.description.abstractBackground: A growing body of literature has suggested that effective emotion regulation is influenced by cognitive function. Maintenance and manipulation of internal representations occur in working memory (WM), and impairments of WM have been reported in patients with bipolar disorder. Methods: We examined the manipulation ability of internal representations in WM using mental rotation (MR) tasks, and compared the task performances of euthymic bipolar I disorder patients to those of schizophrenia patients and healthy controls. In this study, 20 euthymic bipolar I disorder patients, 20 schizophrenia patients, and 38 healthy controls were recruited. People and letter MR tasks were employed to evaluate the ability of WM manipulation. Results: Compared to healthy controls, euthymic bipolar I disorder patients showed substantially higher error rates of people MR task and slower responses in both people and letter MR tasks. Schizophrenia patients showed no difference in error rate and response time in MR tasks compared to healthy controls; however, they showed significantly slower responses in people MR task compared to controls. MR task performance was not different between euthymic bipolar and schizophrenia patients. Conclusion: Our study results indicate that manipulation of internal representation, especially in the egocentric MR, is impaired in bipolar disorder even in the emotionally-stable state. We speculate that impaired imagery manipulation might be related to alterations in empathic ability, susceptibility of mental imagery, and emotion regulation strategies observed in bipolar disorder.-
