In the December 1996 issue of the ARCHIVES, Servan-Schreiber et al1 revealed the results of the application, in a clinical setting, of their pivotal work on the neural network of context information processing in schizophrenia.1,2

We replicated this study in a sample of consecutively admitted patients with schizophrenia (n=15, 12 men, 3 women; age, 32.86±8.16 years [mean±SD]; length of illness, 8.53±6.32 years [mean±SD]; years of education, 11.06±3.26 [mean±SD]) and healthy controls (n=15) matched for sex, age, and years of education (29.46±5.13 years and 13±3.20 [mean±SD], respectively), using the modified version of the A-X Continuous Performance Test.1 All patients had relapsing multiepisode schizophrenia, and were able to live in the community with maintenance neuroleptic therapy. The task was administered to the patients while they were in a stable state of their illness, immediately before hospital discharge.
