title: Repetition blindness in schizophrenic patients.
abstract: Repetition blindness is the failure to report the detection of repeated items in rapid visually presented lists. It can be explained in terms of either a processing limitation or an active inhibitory process. In two studies conducted in either English or German language we set out to induce repetition blindness under various conditions in a total of 47 control subjects and 30 schizophrenic patients. The patients displayed the phenomenon to at least the same degree as normal control subjects. These results render unlikely accounts of repetition blindness which involve processes known to be dysfunctional in schizophrenic patients. Moreover, the study provides an example of how the performance of schizophrenic patients can constrain theories of normal cognition.
