Persons suffering from schizophrenia have a different perception of time than healthy individuals. There is far more variation in the way that a time interval is perceived by people with schizophrenic disorders than by those who do not have the condition. Patients with schizophrenia are also less precise when it comes to judging the temporal order of events. These are the conclusions drawn from the results of a meta-analysis undertaken by psychologists at Johannes Gutenberg University Mainz (JGU), for which they evaluated 68 international publications from the past 65 years and compared the data of 957 schizophrenia patients with that of 1,060 healthy control persons.
