Figure 1
Pavlovian contingency space. The x-axis represents the conditional probability that the unconditioned stimulus (US) occurs together with the conditioned stimulus (CS). The y-axis represents the probability that the US occurs without the CS. There is no contingency between both stimuli on the diagonal line where both probabilities are equal (after Seligman, Maier and Solomon, 1971).
