Abstract
Time perception has long been known to be impaired in schizophrenia. Moreover, recent neuropsychological theories have postulated abnormalities of cognitive motor control in schizophrenia. However, the intersection of these two topics has rarely been studied, and it is unclear what role subjects' own actions may play in the construction of subjective time representation. The present experiment compared the performance of 19 patients with schizophrenia and 24 normal controls in a timing judgment task. The results show that patients bind two consecutive movements more strongly than controls. This anomaly could play a role in the subjective pathological experiences of patients.
