Registered Behavior Technician (RBT) Practice Exam

A is incorrect because it describes a punisher, not a reinforcer. A punisher decreases the rate of a behavior, while a reinforcer increases the rate.

C is incorrect as it describes punishment, not reinforcement. Punishment involves the presentation of an aversive stimulus, while reinforcement involves the presentation of a desired stimulus.

D is incorrect because it describes a discriminative stimulus, not a reinforcer. A discriminative stimulus is presented before a behavior and signals the availability of a reinforcer.

Option B is the correct answer as it captures the definition of a reinforcer - an event that follows a behavior and increases the likelihood of that behavior occurring again in the future. The other options do not accurately describe reinforcement.
