Functional behavior assessments are designed to create behavior interventions that differ from traditional interventions in what major way?

• A. Interventions focused on comparing a student's behavior at home with his behavior at school
• B. Interventions created using functional behavior assessments attempt to identify the purpose served by a particular behavior and substitute a replacement behavior for it, while traditional interventions simply penalize undesirable behaviors
• C. Traditional interventions are student-centered while interventions created using functional behavior assessments are teacher-centered
• D. Traditional interventions are proactive, while interventions created using a functional behavior assessments are reactive

Answer: (B)

The main idea being tested is that functional behavior assessments guide interventions by uncovering the function a behavior serves and then teaching a replacement behavior that achieves the same outcome, rather than simply punishing the undesired behavior. When a behavior is analyzed through an FBA, we look at what happens before (the antecedents) and after (the consequences) to determine why the student performs it—common functions include gaining attention, escaping or avoiding a task, obtaining a tangible reward, or automatic reinforcement. With that understanding, the intervention targets altering those conditions: we change the triggers and the outcomes so the student can obtain the same function through an appropriate behavior. For example, if a student yells to get attention, an FBA-informed plan might teach a quiet request for attention and provide attention for that, while ensuring the undesired behavior no longer results in the same payoff.

Other choices don’t capture this core emphasis. It’s not about comparing behavior at home versus school, nor about whether interventions are student-centered or teacher-centered, and it doesn’t hinge on a simple proactivity versus reactivity distinction. The defining feature is the function-based planning that substitutes a replacement behavior to meet the same need.
