Distinguishing Positive and Negative Reinforcement
Reinforcement is a foundational concept in ABA. Both positive and negative reinforcement generally increase behavior. However, many students confuse the two. Understanding the distinction is crucial for your RBT practice test.
Positive Reinforcement
Positive reinforcement involves adding a stimulus following a behavior to increase that behavior in the future. Think of it as "adding a plus." For example, giving a child a sticker for completing a math problem adds a desirable item.
Negative Reinforcement
Negative reinforcement involves removing an aversive stimulus following a behavior to increase that behavior. Think of it as "subtracting a minus." For instance, putting on a seatbelt to stop the annoying car alarm removes the noise.
Common Misconceptions
Negative reinforcement is not punishment. Punishment decreases behavior, whereas reinforcement always increases behavior. If the behavior happens more often in the future, it was reinforcement.
Exam Tips for Reinforcement
When analyzing a scenario, ask two questions: 1. Did the behavior increase or decrease? (Increase = Reinforcement). 2. Was something added or removed? (Added = Positive, Removed = Negative). This simple logic check solves most questions.
