Visuoperceptual processes in brain damaged patients on the digit symbol substitution test

Abstract

Alcoholic Korsakoff patients, patients with right hemisphere damage, and chronic alcoholics are impaired on the digit symbol substitution task (DSST) of the WAIS. To determine whether these deficits were related to psychomotor or visuoperceptive factors, several tasks and modifications of the DSST were administered to these three patient populations. While it was evident that psychomotor retardation contributed to the patients' poor performance, impairments in visuoperceptive processing were also found to be involved in the DSST performance of the three patient groups. It was concluded that while a psychomotor factor is the crucial variable in the performance of intact normal subjects, any of a number of visual processing variables (e.g., visual scanning, contour formation and organization) must be considered in assessing the deficits of brain damaged patients.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The DSST is sensitive in alcoholic Korsakoff patients, patients with right hemisphere damage, and patients with chronic alcoholism.

    “For example, Glosser et al27 noted the sensitivity of the DSST in alcoholic Korsakoff patients, patients with right hemisphere damage, and patients with chronic alcoholism.”
  • In alcoholic Korsakoff patients, patients with right hemisphere damage, and patients with chronic alcoholism, visuoperceptive processing impairments are also involved in DSST performance.

    “While psychomotor retardation contributed to impaired performance in these patient populations, the investigators, using other cognitive measures, determined that visuoperceptive processing impairments were also involved in DSST performance.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
