TL;DR: In this paper, three experiments were conducted using tachistoscopically presented stimuli in order to evaluate these two stages of information processing (iconic storage and speed of processing) in schizophrenic and control subjects and found that, independent of iconic storage and sensory registration, slow information processing is a relatively stable deficit of schizophrenic patients with a poor prognosis.

TL;DR: The results suggest that there are cultural differences within ethnic groups that relate to neuropsychological test performance, and that accounting for acculturation may improve the diagnostic accuracy of certain neuropsychology tests.

TL;DR: It is confirmed that the schizophrenic patients are slow information processors and that antipsychotic medication probably does not cause, and may actually reverse, slowness of information processing in schizophrenic Patients.

TL;DR: Schizophrenics were compared to schizoaffective, bipolar, and nonpsychotic depressed patients in a visual masking paradigm in which an informational target stimulus was followed at varying intervals by a noninformational masking stimulus.

TL;DR: The authors found that response consistency has better predictive and convergent validity than does response speed, and tasks which demand dynamic memory processing predict intelligence better than do tasks which require only stimulus encoding and simple stimulus/response translations.
