Document Summary
Affective extension of sometime opponent theory (aesop) The pairing of the cs and the ucs enables the cs to later elicit the ucr, but as the cr. In some cases, cr and ucr seem opposite each other (elicit opponent responses) In many cases, cr and ucr are just not the same. Ucr morphine = analgesia (reduced sensitivity to pain) Cr light, tone, etc. = hyperalgesia (increased sensitivity to pain) Drug tolerance repeated use of drugs result in reduced effectiveness and need for increasingly larger doses to get the same pharmacological effect) Interoceptive cues (stimuli originating within the body that are related to the functioning of an internal organ or the receptors that internal organs activate) lead to conditioned drug tolerance. In a hospital setting, injecting patient w/ an iv could be conditioning them. Evidence for conditioning"s role in drug tolerance: Exposure to the cs w/o ucs, once association has been established, results in.
