Validation of a Behavior Analysis Methodology: Variation of Vigilance in Night Driving as a Function of the Rate of Carboxyhemoglobin

Abstract

This study is concerned with problems of consistent behavioral efficiency during a night driving test on a specially equipped vehicle. Driving accuracy and cortical arousal level were objectively measured by parameters which were normalized, permitting a covariations analysis in terms of a standardized experimental situation.

The validation of an original methodology of behavior analysis allows us to consider a discriminant approach of the alertness state for ergonomical or psychopharmacological problems. An application concerning the effects of carbon monoxide traces on vigilance in relation to car driving at night is described.
