Carbon Monoxide and Human Performance: A Methodological Exploration
Studies of the effects on performance of low concentrations of toxicological agents are vulnerable since, if there is an effect, it is likely to be very small and therefore likely to be overwhelmed by task and procedural variables. Experiments using human subjects are especially vulnerable since the restrictions of such use may demand even smaller exposure levels than used with animals, and reversible effects when they do occur. It is important, therefore, that such experiments be conducted with maximal efficiency, that is, so as to obtain the most information with the least exposure. Accomplishing that requires a careful consideration in advance of the interpretations that can be associated with task conditions and of the dependent measures that can be used.
