Which component best characterizes a function-based hypothesis in a Behavior Intervention Plan?

• A. It focuses on the form of the behavior rather than environmental variables.
• B. It specifies contingencies and environmental variables that maintain the problem behavior.
• C. It ignores antecedents and focuses only on consequences.
• D. It recommends punishment as the primary strategy.

Answer: (B)

The key idea is that a function-based hypothesis identifies the environmental variables and contingencies that maintain the problem behavior. This means examining what happens before the behavior (antecedents) and what happens after (consequences) that reinforces it, so you can see why the behavior occurs and how to change it. The correct choice reflects this by specifying the contingencies and environmental variables that keep the behavior going, which then guides the intervention to alter those contingencies or teach a better way to achieve the same function. For example, if a student yells to gain attention, the plan should note that attention is the maintaining consequence and then design strategies that provide appropriate attention for desired behaviors while reducing attention following the problem behavior. The other options fall short because they miss the role of environmental triggers, focus only on consequences without antecedent context, or rely on punishment as the primary method rather than a function-based approach.
