What is the purpose for which the target behavior occurs?

• A. The function of the behavior
• B. A random occurrence with no purpose
• C. To receive punishment
• D. To occupy time during session

Answer: (A)

The main idea is that a behavior happens for a function—the reason it occurs and the consequence it produces. When we observe a target behavior, we consider what happens after it: does it bring attention, help the person escape a demand, provide access to a preferred item, or give an automatic sensory reinforcement? Those consequences reinforce the behavior and make it more likely to occur again. So the purpose behind the behavior is its function, and identifying it helps us design replacement behaviors that achieve the same outcome in a more appropriate way. The other options aren’t correct because behaviors aren’t just random events or simply done to punish or to fill time; they’re driven by the reinforcing outcomes they produce.
