Which of the following best illustrates negative reinforcement?

Negative reinforcement involves the removal of an aversive stimulus, which increases the likelihood of a behavior being repeated. In this case, the scenario that best illustrates negative reinforcement is when the noisy alarm is removed upon the completion of a task. The noisy alarm acts as an unpleasant stimulus, and its removal when the task is finished encourages the individual to complete tasks in the future to avoid that unpleasant sound.

This concept is distinct from other situations involving positive reinforcement, punishment, or the removal of privileges. For instance, giving a child candy for finishing homework represents positive reinforcement, as it adds a pleasant stimulus following a desired behavior. Scolding a student for not paying attention illustrates a form of punishment that aims to decrease undesired behavior rather than reinforce a desired one. Taking away privileges for inappropriate behavior is also a method of punishment, designed to discourage negative behaviors rather than reinforcing positive actions.
