Abstract

Reward magnitude in Phase 1 (1 or 16 pellets) and Phase 2 (1 or 16 pellets) was varied in a 2 * 2 factorial design employing 48 naive female rats as Ss. Resistance to extinction (Phase 3) was influenced by Phases 1 and 2 reward magnitudes. Previous studies, employing a smaller number of trials, failed to find an influence of Phase 1 reward on extinction. The present and previous results are interpreted within sequential theory.
