What is a key characteristic of negative reinforcement?

Negative reinforcement is characterized by the removal of an unwanted stimulus following a specific behavior, which then increases the likelihood of that behavior occurring again in the future. This concept is grounded in the principles of operant conditioning, where behaviors are reinforced or discouraged based on the consequences that follow them. By eliminating an aversive condition, such as a loud noise or an unpleasant situation, negative reinforcement effectively encourages the desired behavior.

In contrast, introducing a positive stimulus, such as verbal praise or rewards, pertains to positive reinforcement rather than negative reinforcement. Adding chores as a form of punishment constitutes a punitive action rather than reinforcement. Therefore, the correct answer highlights the essential nature of negative reinforcement, which focuses on the removal of undesired stimuli to promote positive behavior.
