Abstract
Acquisition rates of the rabbit’s classically conditioned nictitating membrane response were determined for three experimental groups, subjected to 5 sec white noise bursts at 10, 30, or 50 sec after CS-US offset, and compared with the performance of a non-noise control group. Bursts of white noise in the ITI significantly depressed conditioning rates, with the greatest depression produced by the 30 sec post-US burst.
