Visual evoked potentials of a group of 25 schizophrenic patients, a group of 13 neurotics, and a group of 24 healthy subjects were recorded before and after Kraepelin performance test. Soon after performance of the addition test for 15 min. amplitudes of later components (waves IV, V, and VI) of the potential were reduced in schizophrenics, while neurotic patients and healthy subjects did not show such changes.
