Define functional analysis in behavioral assessment.

• A. A method to identify the antecedents, behaviors, and consequences that maintain problematic behavior and determine interventions
• B. A method to calculate IQ
• C. A method to assess dreams
• D. A method to measure heart rate

Answer: (A)

Functional analysis in behavioral assessment examines why a behavior occurs by testing how different environmental triggers (antecedents) and after-behavior consequences influence it. It aims to uncover the function the behavior serves—such as getting attention, escaping a demand, obtaining a preferred item, or receiving automatic reinforcement—by systematically manipulating conditions and observing changes in the behavior. When a particular arrangement reliably increases the behavior and other arrangements do not, that pattern identifies the maintaining function. This information then guides interventions that match the function, such as altering the consequence or teaching an appropriate replacement behavior. It’s an experimental way to pinpoint what keeps the problem behavior going, and it isn’t about IQ, dreams, or simple physiological measures like heart rate.
