How is differential reinforcement of low rates of responding (DRL) typically applied?

• A. By establishing a limit on the acceptable rate of a behavior
• B. By reinforcing any behavior during a time interval
• C. By replacing an unwanted behavior with an incompatible one
• D. By increasing the occurrence of a desirable behavior

Answer: (A)

Differential reinforcement of low rates of responding (DRL) is primarily applied by establishing a limit on the acceptable rate of a behavior. This practice is designed to encourage a decrease in the frequency of a particular behavior while still allowing for its expression, albeit at a lower rate. For example, in a classroom setting, a teacher may set a rule that students can call out answers but can only do so twice during a given period. By reinforcing the student when they adhere to this limit, the teacher is effectively using DRL to promote more controlled and appropriate behavior.

This approach is particularly useful in managing behaviors that should occur but not excessively, allowing for the benefits of the behavior to be retained while reducing its occurrence to a more acceptable level. In contrast, other strategies mentioned do not involve setting limits on frequency, focusing instead on promoting behaviors or completely replacing them, which is not the goal of DRL.
