What does SR+ denote in behavior analysis?

Negative reinforcer
Positive reinforcer
Primary reinforcer
Conditioned stimulus

The correct answer is: Positive reinforcer

In behavior analysis, SR+ denotes a positive reinforcer. A positive reinforcer is a stimulus that, when delivered following a behavior, increases the likelihood that the behavior will occur again in the future. This concept is rooted in operant conditioning, where behaviors are shaped through the consequences that follow them. By providing a positive outcome (such as praise, a token, or a preferred item) after a desired behavior, the individual is more likely to repeat that behavior. The term SR+ emphasizes that the reinforcing agent is something that is added (hence “+”) to the environment following the behavior. This is an essential element in behavior modification strategies used in Applied Behavior Analysis (ABA), allowing practitioners to enhance desirable behaviors effectively.
