Cognitive manipulation of GSR extinction: analogues for conditioning therapies.

Cognitive determinants of GSR activity during extinction trials were examined following conditioning. Conditioned GSRs extinguished rapidly when subjects were informed the UCS would not again be administered, compared to subjects not given this information. Of greater interest was the finding that (false) high feedback concerning subjects' responsivity to the Cs+ during extinction served to maintain GSR activity at a higher level than subjects receiving (false) low feedback. The relationship was observed within both information conditions. Implications are drawn for both aversive conditioning therapy and systematic desensitization.
