title: [Choice reaction time (CRT) in humans after administration of lorazepam].
abstract: Eight normal subjects were tested on auditory and visual choice reaction time and Tapping-Speed Test before and after two hours by administration of lorazepam (2.5 mg per os). CRTs slightly increase but not significantly; Tapping-Speed Test does not show changes. Nevertheless a significant increase of errors in all trials suggest a moderate decrease of performance after lorazepam.
