Which term describes the process by which presenting a stimulus after a behavior increases its future frequency under similar conditions?

• A. Positive Reinforcement
• B. Premack Principle
• C. Programming Common Stimuli
• D. Principle of Behavior

Answer: (D)

Reinforcement increases the future frequency of a behavior when a stimulus is presented after that behavior occurs. When the added stimulus strengthens the behavior, we call this positive reinforcement. The description matches this direct mechanism: a stimulus is presented contingent on the behavior, leading to more of that behavior in similar situations. The Premack Principle involves using access to a preferred activity as a reinforcer, which is a different way of strengthening behavior. Programming Common Stimuli and the Principle of Behavior refer to broader concepts or strategies, not the specific act of adding a stimulus after a response to increase its occurrence.
