Which of the following correctly defines positive punishment?

The definition provided in the correct answer emphasizes that positive punishment involves the presentation of a stimulus designed to decrease the occurrence of a specific behavior. In behavioral terms, the term "positive" refers to the addition of something in an attempt to diminish unwanted behavior.

Essentially, when an undesirable behavior occurs, a stimulus is introduced in response, which leads to a decrease in that behavior over time. For example, if a student interrupts frequently, a teacher might give a reprimand or impose a less pleasant task to discourage that behavior. Over time, the idea is that the unwanted behavior will occur less frequently as the individual learns to associate the behavior with the unpleasant outcome.

Other options presented do not align with the definition of positive punishment. For instance, the first option refers to the removal of a stimulus, which is indicative of negative punishment rather than positive. The third option describes reinforcement by introducing a reward, which is aimed at increasing behavior rather than decreasing it. Lastly, the fourth option describes a disciplinary action that involves withdrawing privileges, which again relates to negative punishment rather than the addition of a stimulus to decrease behavior.
