Effects of percent relief and number of N-R transitions on extinction in relief conditioning

Abstract

Forty rats were trained for 10 acquisition and 20 extinction trials in a cold-water relief conditioning apparatus. Two levels of percent relief (30% vs. 70%) and number of transitions from nonrelief (N) to relief (R) trials (1 vs. 3) were factorially combined. Resistance to extinction was found to be a function of percent relief rather than number of N-R transitions.
