Purpose:

The purpose of this study is to test the effect of modafinil on the negative symptoms, such as blunted affect and social withdrawal, of schizophrenic patients and to determine modafinil's effect on excessive daytime sleepiness.

Subjects will receive either modafinil or placebo, supplied by the sponsor. The study drug will be taken by mouth once daily in the morning. The titration schedule will be as follows: 1. The beginning does will be 50mg for 2 weeks 2. The study medication will be increased to 100mg at the week 2 study visit 3. The study medication will be increased to 200mg at the week 4 study visit and will continue for the remaining 4 weeks of the study. If subjects are unable to tolerate dosage increases, the dose will be decreased to the previous level.
