A changing criterion experimental design is MOST beneficial for:

• A. Teaching a new skill
• B. Researching group behavior
• C. Helping a client reduce his echolalia
• D. Assessing environmental factors

Answer: (C)

A changing criterion experimental design is particularly effective for situations where a specific behavior needs to be gradually shaped or modified over time. This design involves systematically changing the criteria for reinforcement, which allows for the measurement of how the client’s behavior improves as the criteria become more stringent. In the context of helping a client reduce echolalia, the changing criterion design is beneficial because it allows the behavior analyst to set specific, incremental goals for reducing instances of echolalia. For example, the initial criterion might be to decrease echolalia from an average of ten instances per week to eight, and as the client meets this goal, the criterion can be changed to seven, and so forth. This gradual approach ensures that the client can achieve success with each change, maintaining motivation and providing clear, measurable outcomes. The other options do not align as closely with the strengths of a changing criterion design. Teaching a new skill generally benefits more from a direct instruction approach, researching group behavior may require different methodologies that capture interactions among group members, and assessing environmental factors usually involves observational studies rather than altering conditions incrementally over time.
