Examples Versus Positive Reinforcement Versus Punishment Effectiveness Negative reinforcement is a term described by B. F. Skinner in his theory of operant conditioning. In negative reinforcement, a response or behavior is strengthened by stopping, removing, or avoiding a negative outcome or aversive stimulus. Verywell / Jessica Olah How Does It Work? Negative reinforcement works to strengthen certain behaviors by removing some type of aversive outcome. As a form of reinforcement, it strengthens the behavior that precedes it. In the case of negative reinforcement, it is the action of removing the undesirable outcome or stimulus that serves as the reward for performing the behavior. Aversive stimuli tend to involve some type of discomfort, either physical or psychological. Behaviors are negatively reinforced when they allow you to escape from aversive stimuli that are already present or allow you to completely avoid the aversive stimuli before they happen. Deciding to take an antacid before you indulge in a spicy meal is an example of negative reinforcement. You engage in an action in order to avoid a negative result. One of the best ways to remember negative reinforcement is to think of it as something being subtracted from the situation. When you look at it in this way, it may be easier to identify examples of negative reinforcement in the real world. Examples of Negative Reinforcement Looking at some real-world examples can be a great way to get a better idea about what negative reinforcement is and how it works. Consider the following situations: Before heading out for a day at the beach, you slather on sunscreen (the behavior) to avoid getting sunburned (removal of the aversive stimulus). You decide to clean up your mess in the kitchen (the behavior) to avoid getting into a fight with your roommate (removal of the aversive stimulus). On Monday morning, you leave the house early (the behavior) to avoid getting stuck in traffic and being late for work (removal of an aversive stimulus). At dinner time, a child pouts and refuses to eat her vegetables for dinner. Her parents quickly take the offending veggies away. Since the behavior (pouting) led to the removal of the aversive stimulus (the veggies), this is an example of negative reinforcement. Can you identify the negative reinforcer in each of these examples? Sunburn, a fight with your roommate, being late for work, and having to eat vegetables are all negative outcomes that were avoided by performing a specific behavior. By eliminating these undesirable outcomes, preventive behaviors become more likely to occur again in the future. Do You Unwittingly Encourage Bad Behavior in Your Kids? Negative vs. Positive Reinforcement Positive reinforcement is a type of reinforcement that involves giving someone the desired reward in response to a behavior. This might involve offering praise, money, or other incentives. Both positive and negative reinforcement work to increase the likelihood that a behavior will occur again in the future. You can distinguish between the two by noticing whether something is being taken away or added to the situation. If something desirable is being added, then it is positive reinforcement. If something aversive is being taken away, then it is negative reinforcement. Negative Reinforcement vs. Punishment One mistake that people often make is confusing negative reinforcement with punishment. Remember, however, that negative reinforcement involves the removal of a negative condition to strengthen a behavior. Punishment involves either presenting or taking away a stimulus to weaken a behavior. Consider the following example and determine whether you think it is an example of negative reinforcement or punishment: Luke is supposed to clean his room every Saturday morning. Last weekend, he went out to play with his friend without cleaning his room. As a result, his father made him spend the rest of the weekend doing other chores like cleaning out the garage, mowing the lawn, and weeding the garden, in addition to cleaning his room. If you said that this was an example of punishment, then you are correct. Because Luke didn't clean his room, his father punished him by making him do extra chores. If you are trying to distinguish between negative reinforcement or punishment, consider whether something is being added or taken away from a situation. If an unwanted outcome is being added or applied as a consequence of a behavior, then it is an example of punishment. If something is being removed in order to avoid or relieve an unwanted outcome, then it is an example of negative reinforcement. Effectiveness Negative reinforcement can be an effective way to strengthen the desired behavior. However, it is most effective when reinforcers are presented immediately following a behavior. When a long period elapses between the behavior and the reinforcer, the response is likely to be weaker. In some cases, behaviors that occur in the intervening time between the initial action and the reinforcer are may also be inadvertently strengthened as well. Some experts believe that negative reinforcement should be used sparingly in classroom settings, while positive reinforcement should be emphasized. While negative reinforcement can produce immediate results, it may be best suited for short-term use. A Word From Verywell Negative reinforcement can have a powerful effect on behavior, but it tends to be most useful when used as a short-term solution. The type of reinforcement used is important, but how quickly and how often the reinforcement is given also plays a major role in the strength of the response. The schedule of reinforcement that is used can have an important impact not only how quickly a behavior is learned, but also on the strength of the response.
