Bleuler revisited: psychomotor slowing in schizophrenia as part of a catatonic symptom cluster.
In schizophrenia, psychomotor slowing and stereotypy are poorly delineated from cognitive deficits like diminished processing speed. Inpatients' performance outcomes on a line-copying task, a task assessing stereotypy and a processing-speed task are compared. Results suggested that psychomotor slowing and stereotypy are related and may represent a catatonic symptom cluster.
