Which method is recommended for increasing the number of responses required in a ratio schedule?

The recommended method for increasing the number of responses required in a ratio schedule is to do so gradually. This approach allows for an effective adjustment process where the subject can adapt to the increasing demands without becoming overly frustrated or discouraged. Gradually increasing the ratio helps maintain motivation and consistent performance, as it provides the learner with the opportunity to successfully meet new expectations while reinforcing learned behaviors.

In behavioral training, sudden or rapid increases may lead to a drop in performance, as the subject might struggle to keep up with the new requirements. Gradually escalating the expectations can support sustained engagement and facilitate a more effective learning experience, making it more likely that the new higher ratio will be internalized as a part of the subject's behavior.
