Study Summary
This study will determine whether eszopiclone will normalize sleep patterns and restore sleep-dependent enhancement of motor skill learning in patients with schizophrenia. The investigators will compare subjects taking a placebo to those taking 3 mg of eszopiclone with regard to: sleep architecture and sleep latency as measured by actigraphy and polysomnography and sleep-dependent motor skill learning.
Primary Outcome
The finger tapping task involves pressing four numerically labeled keys on a standard computer keyboard with the fingers of the left hand, repeating a five element sequence (4-1-3-2-4) "as quickly and accurately as possible" for 30s. During both training and test sessions, participants alternated tapping and resting for 30s for a total of 12 tapping trials. The measure was the number of correct sequences per trial. Overnight change was the percent change in correct sequences from the last three
