Differential Reinforcement of Low Rates of Responding (DRL) is a behavioral procedure aimed at reducing, but not eliminating, a specific behavior. DRL has three distinct procedure components designed to achieve this goal.
The three types of DRL are:
| Type of DRL | Description |
|---|---|
| Full-Session DRL | Reinforcement is delivered if the behavior occurs at or below a specified low rate throughout an entire session. |
| Interval DRL | Reinforcement is provided if the behavior occurs at or below a specified low rate within a specific time interval. |
| Spaced-Responding DRL | Reinforcement is given only if a certain amount of time has passed since the last instance of the behavior. |
In essence, DRL procedures teach an individual to perform a behavior less frequently or less intensely, often summarized as "do this, but not so much, or not so often!"
