RESUMO
Perceptual span was assessed in schizophrenic, bipolar affective disorder-manic, bipolar affective disorder-depressed, and nonpsychotic inpatients. Both schizophrenics and manics processed less information than depressives, and did not differ from each other. This suggests that reduced span may be a concomitant of psychoses characterized by distractibility and thought disorder, rather than a trait specific to schizophrenia.

A hand-held tachistoscope for use at the bedside was constructed and used to examine 40 normal controls and 170 psychiatric and neurological patients. This instrument quickly provided an index (perception time) which distinguished between idiopathic psychiatric illness and delirium, and between cortical and subcortical neuropathology. Slow perception time was seen in patients with delirium or cortical neuropathology.
