Abstract
Two studies were performed to assess the effects of within-Ss and between-Ss reinforcement parameters on resistance to extinction. A two-way runway situation enabled rats to experience one sequence of reinforcements and nonreinforcements while running in one direction and another while running in the other direction (within-Ss comparison). Groups of Ss experienced different overall sequences (between-Ss comparisons). The two directional sequences determined resistance to extinction when the nontransformed extinction data were examined. Manipulating the within-Ss reinforcement contingencies made it possible to obtain a “reverse” partial-reinforcement effect. Rate-corrected data (Anderson, 1963), however, were more sensitive to the overall sequence.
