In Changing Criterion Design, how is behavior change assessed?

• A. By maintaining a constant reinforcement schedule
• B. By gradually altering the criterion for reinforcement
• C. By introducing multiple probes at varied intervals
• D. By using a control group for comparison

Answer: (B)

In Changing Criterion Design, behavior change is assessed by gradually altering the criterion for reinforcement. This method involves setting specific performance criteria that must be met before reinforcement is delivered. As the individual meets these gradually increasing or changing performance standards, it allows for a clear measurement of behavior change over time.

The focus on incrementally changing the criteria enables practitioners to observe whether the behavior improves as the criteria become more stringent. This gradual adjustment allows for the identification of a functional relationship between the behavior and the established criteria, demonstrating whether the intervention is effectively influencing the target behavior. By systematically modifying the criteria and observing the corresponding changes in behavior, it becomes possible to assess the effectiveness of an intervention in a nuanced manner that reflects real-world expectations.

In summary, the key feature of the Changing Criterion Design is its emphasis on the gradual shift in criteria for reinforcement, making this approach particularly useful for evaluating the effectiveness of behavioral interventions in a structured way.
