According to a 5 X 2 factorial design, 10 groups of rats received different numbers of continuously rewarded trials (NG) in a straight runway, i.e., 24NG, 48NG, 84NG, 132NG, or 192NG, followed by either a latent extinction experimental treatment (LEE) or a latent extinction control treatment (LEC). All Ss then received 22 experimental extinction trials in the runway. Resistance to extinction was found to be an increasing monotonic function of NG for LEE groups, and an increasing-decreasing nonmonotonic function of NG for LEC groups. These relations are compatible with the S-R model relating extinction performance in the runway to the joint operation of rG-sG and rF-sF, firstly as these 2 factors are assumed to be differentially related to NG, and secondly as they can also be assumed to be differentially affected by the LEE treatment.
