Abstract

Two groups of rats were given CER conditioning and extinction, using the Jacobs, Buttrick, and Kennedy (1988) methodology. For one group, loud noise was introduced concurrently with the light CS in extinction. Loud noise was found to potentiate the CER in lick suppression. On a final test day of extinction, both groups received CS-alone presentations. No evidence of protection from extinction by the noise was found. The results were related to other effects of noise on extinction in aversive paradigms.
