Getting ready for your BCBA exam? You’re in the right place.

I created RBTExamPrep.com to give you the most realistic BCBA mock exam experience possible 185 questions designed to feel just like the real thing.

My goal isn’t just to help you pass, but to help you understand every concept deeply.
Whether you get a question right or wrong, you’ll see detailed feedback explaining why, so you’ll be ready for that type next time. I want you to walk into test day feeling confident, calm, and prepared.

Many students have shared that these questions felt almost identical to the real exam and that’s exactly what I was aiming for. I’d love to hear how you did please share your score in the comments below! It really helps encourage others who are preparing for the exam. 🙂

I built this site to keep high-quality BCBA prep resources free and accessible for everyone, which is why it’s supported by ads. If it helped you, it’d mean a lot if you shared it with your peers.

If you want to keep practicing, check out the BCBA section for more tests and study materials!

#1. A two-year-old child’s spontaneous mands for a preferred toy have decreased significantly over the past week. The parents express concern that they may have inadvertently punished the child’s communication. However, a review of their interactions reveals no direct application of aversive stimuli or removal of positive reinforcement immediately following the mands. Based on the principles of Applied Behavior Analysis and the information provided, what is the MOST likely behavioral phenomenon occurring that explains the decrease in the child’s mands?

The child is experiencing a decrease in motivation for the toy, indicating a satiation effect.

The parents are unintentionally reinforcing a functionally equivalent, alternative behavior, making the mands less efficient.

The child’s mands are undergoing extinction due to the parents’ consistent lack of attention.

The child’s communication skills are regressing, necessitating a re-assessment of developmental milestones.

The provided text explicitly clarifies that when theres no indication of punishment or extinction occurring a decrease in a target behavior often means that a different functionally equivalent behavior is being reinforced instead This alternative behavior then competes with the target behavior leading to its decrease While satiation could decrease motivation and extinction involves withholding reinforcement the scenario specifically negates punishment and points towards an interactional cause for the decrease making the reinforcement of an alternative behavior the most probable explanation provided within the context Regression is a developmental concern not a primary behavioral principle explanation for a recent behavioral change in this context
