Table 1. Order of experimental conditions, showing the conditional probabilities of a reinforcer's being arranged on Alternative x given an immediately preceding reinforcer on that alternative, p(Rx|Rx). Because the conditional probabilities were the same on both alternatives, the arranged relative reinforcer ratio was 1:1 throughout. In Condition 8, the first reinforcers in a session were arranged by a 63-step, pseudorandom binary sequence.
