A visual word identification task was used to measure the type of selective attention that occurs spontaneously when there are multiple stimuli, all potentially relevant, and insufficient time to process each of them fully. This task presents two words simultaneously, one above the other, for 200 ms, and periodically requires the subject to identify either the upper or the lower word. We tested schizophrenic patients, manic-depressive patients, and normal controls under a baseline divided attention condition with no predictability and then introduced a degree of predictability into the upper location that normally results in selective attention to the lower nonpredictable location. In both the divided attention and the selective attention conditions, the schizophrenic group was just as accurate in identifying words as the other two groups, indicating no deficit in the rate of information processing. However, spontaneous selective attention under conditions of predictability was abnormal in the schizophrenic patients: They paid more attention to the predictable than to the nonpredictable source of information, consequently processingdifferent, notless, information than normal subjects. Abnormal values on a ratio measure of selective attention occured in 85% of the schizophrenic patients compared with only 30% of the manic-depressives and 20% of the normal subjects.
