Final answer:
A conditioning analysis of drug tolerance suggests that drug tolerance is enhanced by homeostatic responses to the drug effect and by cues predicting the drug's effects.
Step-by-step explanation:
A conditioning analysis of drug tolerance suggests that drug tolerance is enhanced by homeostatic responses to the drug effect and by cues predicting the drug's effects. For example, if a person regularly takes a drug in the same environment, their body may become more tolerant to the drug's effects. Additionally, cues such as the sight of drug paraphernalia or being in a specific location associated with drug use can also enhance drug tolerance. Therefore, the best explanation of a conditioning analysis of drug tolerance is statement 1) Drug tolerance is enhanced by homeostatic responses to the drug effect and by cues predicting the drug's effects.
