2 groups of rats were trained to traverse a straight alley under identical patterns of partial reinforcement; a 3rd group received consistent reinforcement. Both partial groups received intertrial reinforcements, one following nonreinforced trials preceding reinforced ones, the 2nd following reinforced trials preceding either reinforced or nonreinforced ones. The 1st partial group was not more resistant than the consistent group, while the 2nd partial group showed the typical partial reinforcement effect.
