Abstract
Discrimination eyelid conditioning was conducted under inhibitory, neutral and facilitatory instructional sets in well-practiced subjects following administration of methaphetamine, diazepam, or a placebo. Discrimination under methaphetamine was superior to the other two drug conditions, primarily as a result of decreased response levels to the unreinforced stimulus. There appeared to be no differences among drug conditions that were attributable to effects of the drugs on responsivity (nonspecific reactivity).
