Once control is achieved, which of the following is appropriate for lengthening the dro interval
when the criterion is no occurrences for 10 minutes
The criterion is 5% higher than that of the previous day, provided control is maintained

the general guideline for increasing the dro interval is
Gradually increase the interval after the problem behavior is under control
An initial dro interval should be set so that
Reinforcement is encountered frequently
Guidelines for the effective use of interval dro include
Determining a procedure for increasing the dro interval, combining dr o with other
procedures, providing reinforcement contingent upon the no occurrences of the target
