“…Finally, both workload level and diazepam induce similar decrements in the amplitude and increases in the latency of various components on the evoked response. These, combined with an increased error rate and longer reaction times, have been found to correspond to decrements in attention, psychomotor skills, perception, vigilance, and cognitive performance capabilities (Donchin, 1977;Rizzuto and O'Donnell, 1981;Seppala, Pavla, Matilla, Kortilla, and Shrotriya, 1980;Wickens, Israel, and Donchin, 1977;Wilson and O'Donnell, 1980 In this manner, 24 male subjects were selected for the experiment. Each was given both an oral and a written explanation of the study, provided the opportunity to ask questions, and asked to sign a consent form.…”

FOR THE COMIMANDER TITLE Iclude Security Clasification)62202F 7184 14 07See reverse side. PERSONAL AUTHOR(S)Capt Anthony P. Rizzuto*, Dr. This study used a 5 mg oral dose of diazepam (valium) and placebo to test potential performance degradation under the influence of a minor tranquilizer. Dependent variables included a wide range of visual and auditory evoked response measures, as well as behavioral, memory, and physiological tasks that generated the measurement of 57 separate indices of human performance for each of 24 subjects during each of four measurement sessions. These dependent variables have been chosen as standardized tasks to be included in a neurophysiological test battery currently under development and testing by the Air Force Aerospace Medical Research Laboratory. This report describes the rationale for usin. these measures as indices of drug effects and outlines recent research using diazepam to induce performance decrements. Results of the experiment showed no generalized substantive effect at this dosage level on the performance variables studied.

“…When the stimulus is sinusoidally modulated the result is called a steady state evoked potential (SSEP). Research in this area suggests that the SSEP may be a useful indicator for mental-state estimation (SpekreiJse, 1966;Regan, 1972;Wilson and O'Donnell, 1980). Using a light stimulus modulated by a sum of sine waves, a steady state evoked potential can be elicited that contains responses at all of the component frequencies of the driving stimulus.…”
