(2001). Pavlovian conditioning and drug overdose: When tolerance fails. Addiction Research and Theary,9(5), 503-513 Tolerance is often a condition that follows repeated exposure to a drug. In this experiment, how did the researchers develop tolerance in the rats? O By selecting rats with exposure to heroin from other experiments O By repeatedly injecting the rats with heroin during the test sessions O By repeatedly injecting the rats with heroin during the pretest sessions What differed between the same-tested and different-tested groups during the test session? O The environment in which the injection was administered O The amount of heroin that was injected O The type of drug that was injected O The number of injections that were administered How did the difference identified in the previous question most likely lead to the difference in fatality rates? O The unfamiliar environment caused the different-tested rats not to anticipate the heroin injection, increasing their fatality rate. O The amount of heroin injected into the different-tested group was just over a fatal level for a rat. O The test session cocktail of drugs for the different-tested group included a drug that had a toxic interaction with heroin.
