What is a focus of DRH and DRL in differential reinforcement?

The focus of differential reinforcement of high rates (DRH) and differential reinforcement of low rates (DRL) is specifically about managing the frequency of behaviors by reinforcing either high or low rates, respectively.

In the case of DRH, the objective is to increase the rate of a desired behavior, making it necessary to provide reinforcement only when the behavior occurs at or above a certain threshold. This is particularly useful in promoting active engagement in a behavior that may need enhancement, such as participation in discussions or physical activities.

Conversely, with DRL, the aim is to decrease a behavior that occurs too frequently but is not entirely undesirable. Reinforcement is provided only when the behavior occurs at lower rates than typical. This approach helps manage excessive behavior that might be disruptive or inappropriate while still allowing the behavior to occur occasionally.

The other options do not align with the core concepts of DRH and DRL. Emphasizing incompatible behaviors relates more to strategies targeting behaviors that cannot occur simultaneously, while completing all behaviors successfully and using various settings for generalization do not specifically address the frequency-focused objective that defines DRH and DRL.
