| Popis: | Using barpress conditioned suppression, we studied the renewal of conditioned fear in rats, an animal model for the relapse of human fears and phobias. We demonstrated ABA renewal when the only differences between Contexts A and B included (1) their odor, (2) their location (i.e., side of room), and (3) unintended differences between copies of the same box at the two sites. Removing either the odor or location cues abolished the renewal effect. We then directly compared the effects of ABA and AAB procedures under two levels of context similarity. Although AAB renewal occurred, ABA renewal was stronger. Adding multiple context distinctions to the three listed above did not significantly enhance either form of renewal. Finally, we directly compared the strengths of AAB, ABC, and ABA renewal. AAB renewal, though again significant, was weaker than ABA and ABC renewal, which did not differ significantly. Fear renewal (relapse) can thus be reduced by extinguishing the fear in the acquisition context, regardless of the nature of the test context. |
