The odds that there was a decrease in the probability of reinforcement after the last reinforcement, as a function of the number of unreinforced trials (extinction trials), following training on continuous or partial reinforcement schedules. The trials/reinforcement during training are written by the curves in the upper left panel. Top row: minimal training (12 reinforcements); bottom row: extensive training (96 reinforcements). Left column: prior odds scaled so that in a sequence of any given length, there is a 1 in 10 chance that it contains a change; right column: even odds of a change in a sequence of a given length. Dashed horizontal lines indicate even odds. The trials required to reach this criterion increase roughly in proportion to the schedule parameter.
