Conclusions Deficits for SCZ patients on the DMTS test of working memory can not be explained by an inability to maintain information over time. Patients with schizophrenia showed slowed encoding of stimuli into working memory. Once this slowing was accounted for, there were no differences in working memory. Circuitry of primate prefrontal cortex and regulation of behavior by representational memory. Storage and executive processes in the frontal lobes.
Schizophrenics show working memory deficits.
All were significantly correlated with the stimulus presentation duration. Clinician Ratings of Test Behavior SCZ CON Relationship to DMTS Stimulus Pres. Five scales were significantly correlated with the stimulus presentation duration needed to meet criterion on the DMTS test. Performance on Cognistat SCZ CON Relationship to DMTS Stimulus Pres.
