title: Performance on the continuous performance test under parametric increase of working memory load in schizophrenia.
abstract: We asked 24 schizophrenia patients and 24 healthy comparison subjects to complete a parametric working memory version of the continuous performance test. Patients exhibited a relatively rapid performance decline with increasing working memory demands. We suggest an interaction between sustained attention and working memory abnormalities in schizophrenia.
