Report on a Continuous Performance Test

Jacques Rutschmann, DSc; Barbara Cornblatt, MBA; L. Erlenmeyer-Kimling, PhD

Arch Gen Psychiatry. 1977;34(5):571-575.

Abstract
• A test of sustained attention (the Continuous Performance Test) was administered to a group of children at risk for the eventual manifestation of schizophrenia and to a group of "normal control" children. Differences in performance between the two groups were attributable to poorer discriminability on the part of the high-risk subjects.
