Use of environmental challenges in behavioral toxicology.
The term environmental challenges encompasses variables that are either known or suspected to affect a baseline of behavior. Environmental challenges can be used to provide information that is important for characterizing the behavioral effects of prior exposure to a toxicant, as well as for revealing effects of the toxicant that may not otherwise be apparent in the baseline under investigation. The use of environmental challenges can be applied in studies of all known classes of behavior, and in each case is limited only to the extent that appropriate variables can be identified and manipulated. Use of environmental challenges may be particularly relevant for studies of schedule-controlled operant behavior because many of the controlling variables have already been well specified. The rationale for using environmental challenges to characterize the behavioral effects of toxicants is very similar to that for using pharmacological challenges; both represent promising new research strategies in behavioral toxicology.
