Each trial had an equal probability of being an oddball trial (p = 1/7), except that the trial after an oddball trial was always a standard trial.
The remaining 4 trials in each session were probe trials in which no reinforcers were delivered, which were interspersed randomly among the standard trials, with the constraint that at least one standard trial occurred between successive probe trials.
