It is well known that inert gas narcosis disrupts human performance on a variety of tasks. Lately, for both practical and theoretical reasons, there has been a good deal of interest in how drugs may influence this impairment. Practical concern is generated by the increase in drug usage and the consequences for the operational safety of divers. Theoretically, there exists a distinct possibility that patterns of drug effects may provide insight into the mechanisms underlying narcosis. In this regard, it has been demonstrated that both nitrous oxide and hyperbaric air increase the intercept but not the slope of the Hick-Hyman choice reaction time function. This function represents a stage of processing involving the choice of a response to a stimulus. It has also been found that ethanol, a depressant, exacerbates narcosis while amphetamine, an excitant, ameliorates it. These experiments used an identical serial choice reaction time task. TRUNCATED
