"The main feature of variable schedules is that, in animals, ratio schedules produce larger response rates than interval schedules for the same reinforcement density. For example, one animal might be trained on a variable ratio schedule and the times at which it received reinforcement could be noted. These time could then be used to form a 'yoked' variable interval schedule for another animal - an interval schedule where the interval between SD onset and the onset of a response-reinforcement contingency is determined by the times at which the first animal received each reinforcement. Typically the second animal would produce much slower response rates on the yoked schedule even though the frequency of reinforcement received by the two animals was more or less the same." --R.W.
