Positive reinforcement is defined as:

• A. Increases probability behavior will occur
• B. Decreases probability behavior will occur
• C. Eliminates a behavior by punishment
• D. Has no effect on behavior

Answer: (A)

Positive reinforcement strengthens a behavior by adding a desirable consequence after the behavior occurs. When something valued is presented immediately after the target action, the likelihood that the behavior will happen again increases. For example, praise or a small reward given right after a client completes a coping skill makes it more likely they’ll use that skill again. This is not about decreasing the behavior or eliminating it through punishment, and it is not about having no effect. For best results, the reinforcement should be contingent on the behavior, meaningful to the person, and delivered promptly.
