What is the primary goal of functional analysis?

• A. Determine the functions of the behavior
• B. Increase the behavior frequency
• C. Classify the behavior by topography
• D. Measure the duration of behavior

Answer: (A)

The main idea being tested is identifying why a behavior happens—the function it serves. Functional analysis uses controlled changes to what happens before and after the behavior to test hypotheses about what reinforces it. The aim is to determine the maintaining consequences or reinforcers, such as gaining attention, escaping a demand, obtaining a tangible item, or providing sensory stimulation. Knowing the function guides the design of effective, function-based interventions (like differential reinforcement or extinction) and helps teach a replacement behavior that serves the same function. The other options miss this core purpose: measuring duration is about data collection, classifying by topography focuses on the form of the behavior rather than why it occurs, and simply increasing frequency is not the goal of the analysis.
