Abstract
Conditioned suppression was demonstrated in rats trained under nondrug conditions and tested under either drug or nondrug conditions. When training occurred under drug conditions, suppression occurred only when testing was also under the drug. Results are interpreted in terms of dissociation between drug and nondrug states rather than as effects on mechanisms of learning and memory.
