The authors investigated the clinical symptomatology, auditory evoked responses, and quantitatively analyzed EEGs of chronic schizophrenic patients with thought process disorder (TPD), schizophrenic patients without TPD, and matched normal volunteers. They describe the differences they found in terms of the variability, shape, latency, and amplitude of the patterns of the evoked potentials for the three groups. They also attempt to relate the neurophysiological findings with some characteristics of thought process disorder.
