Behavior reduction focuses on decreasing problem behaviors while teaching appropriate alternatives. Learn to identify functions of behavior and implement evidence-based interventions under BCBA supervision.
Behavior reduction is a critical component of ABA therapy. This section tests your understanding of why problem behaviors occur and how to safely and ethically reduce them. Key topics include:
Understand the target behavior, function, replacement behavior, and intervention strategies.
Understand that behavior is typically maintained by attention, escape, tangible items, or automatic reinforcement.
Change environmental conditions before the behavior occurs to prevent problem behavior.
Use DRA, DRO, DRI, or DRL to decrease problem behavior while reinforcing appropriate alternatives.
Withhold reinforcement that has been maintaining the problem behavior.
Follow specific safety protocols when dangerous behavior occurs.
Apply time-out, response cost, or other punishment procedures as specified in the behavior plan.
Collect accurate data on both problem behavior and replacement behavior.
Apply reinforcement for appropriate behavior and extinction or punishment for problem behavior as specified.
Ensure that interventions match the identified function of the behavior.
Use response cost (loss of tokens) as part of a comprehensive behavior reduction plan.
Collect data for functional behavior assessments under BCBA supervision.
All behavior serves a purpose. Understanding why a behavior occurs is essential for choosing the right intervention. The four functions are:
Behavior occurs to gain attention from others (positive reinforcement). Example: Calling out in class to get teacher attention.
Behavior occurs to escape or avoid something aversive (negative reinforcement). Example: Tantrums when asked to do difficult tasks.
Behavior occurs to gain access to items or activities (positive reinforcement). Example: Screaming to get a preferred toy.
Behavior produces its own reinforcement (sensory stimulation). Example: Hand-flapping that feels good regardless of others.
The purpose behavior serves: attention, escape, tangible, or automatic
Withholding reinforcement that previously maintained a behavior
Reinforcing an appropriate alternative while extinguishing problem behavior
Reinforcing the absence of problem behavior during a time interval
Modifying the environment before behavior occurs to prevent problems
Process of identifying the function of problem behavior
An appropriate behavior that serves the same function as the problem behavior
Removing a reinforcer after problem behavior occurs
Behavior reduction questions often present scenarios where you must identify the function of behavior or select the appropriate intervention.
1. A child screams when asked to do homework. The teacher sends the child to time-out. The screaming continues to occur. What is the likely function of the screaming?
Answer: B — Time-out removes the child from the homework task, which may reinforce screaming by allowing escape. If screaming continues, it's likely maintained by escape.
2. An RBT implements a procedure where a child earns a token for every 2 minutes without hitting. What differential reinforcement procedure is this?
Answer: C — DRO (Differential Reinforcement of Other Behavior) provides reinforcement when the problem behavior does NOT occur during a specific time interval.
3. A child frequently calls out in class to get the teacher's attention. The teacher stops responding to the call-outs while praising students who raise their hands. What procedures are being combined?
Answer: B — The teacher is using extinction (not responding to call-outs) combined with DRA (reinforcing hand-raising as an alternative behavior).
4. Which of the following is an example of an antecedent manipulation?
Answer: B — Antecedent manipulations occur BEFORE the behavior. Giving a break proactively prevents escape-maintained behavior by addressing the motivation.
5. What should an RBT do if a client engages in dangerous self-injurious behavior during a session?
Answer: B — RBTs must follow crisis/emergency procedures as specified in the behavior reduction plan. Safety is always the first priority.
RBTs implement behavior reduction procedures under BCBA supervision. Never design interventions independently. Always follow the written behavior reduction plan exactly.
Memorize the four functions and practice identifying them in scenarios. Use the mnemonic "SEAT" (Sensory/Automatic, Escape, Attention, Tangible).
Understand the differences between DRA, DRO, DRI, and DRL. Know when each is appropriate based on the behavior and situation.
