DIFFERENTIAL REINFORCEMENT OF LOW RATES
Differential reinforcement of low (DRL) rates: is a schedule of reinforcement in which a
rein- forcer is presented only if a particular response occurs at a low rate.
1. Limited-responding DRL, specifies a maximum allowable number of responses
during a certain time interval in order for a reinforcer to occur.
is useful in two conditions some of the behavior is tolerable but less of it is better.
2. Spaced-responding DRL, requires that a specified behavior not occur during a
specified interval, and after the interval has passed, an instance of that behavior must
then occur in order for a reinforcer to occur.
is useful when the behavior wanted to reduce is actually desirable provided that
it does not occur at too high a rate.
DIFFERENTIAL REINFORCEMENT OF ZERO RESPONDING
Differential reinforcement of zero responding (DRO): A schedule in which a reinforcer
is presented only if a specified response does not occur during a specified period of tim
