![]() ![]() Negative reinforcement is not the opposite of positive reinforcement. It is a part of everyday life, for neurodiverse and neurotypical people alike. There is nothing inherently wrong or bad about negative reinforcement. Subsequently, a person will be more inclined to turn the light off the next time they want to sleep. This is negative reinforcement.Īnother example of negative reinforcement includes turning off a light at night (the light is subtracted), which leads to better sleep. In ABA terms, taking the shower was “negatively reinforced” by taking away (or subtracting) the bad smell. Someone who takes a shower to remove body odor is subtracting their bad smell. To understand the use of negative reinforcement during ABA therapy, it might help to think of “negative” in terms of the mathematical principle of subtracting (as opposed to the qualitative judgment of “negative” to mean something bad). ![]() This could be a noise, an object, a smell, or even a person.įor the full effects of negative reinforcement to be felt, once the stimulus is removed, the child must continue to engage in the behavior that led to the favorable outcome when similar situations arise again. In applied behavior analysis, the “stimulus” is whatever is taken away from the child that was causing them distress. When a child’s behavior causes the removal of a stimulus that they found unpleasant and an impediment to what they wanted to achieve, this is a state of negative reinforcement. The removal of the stimulus (the negative reinforcement) creates a wanted outcome for the person. Negative reinforcement happens when an unwanted stimulus in the environment is taken away because of a person’s behavior. It simply involves removing an uncomfortable stimulus as a method of encouraging desired behavior. Many people associate negative reinforcement with punishment, but it’s not. Types of positive reinforcement that are effective in everyday life include verbal praise or approval, the awarding of status or prestige, and direct financial payment.Though positive reinforcement is the basis of applied behavior analysis, negative reinforcement can also be used. This is because positive reinforcement makes the person or animal feel better, helping create a positive relationship with the person providing the reinforcement. The use of positive reinforcement in changing behavior is almost always more effective than using punishment. It is also important to note that reinforcement and punishment are not simply opposites. One may smoke a cigarette both because it brings pleasure (positive reinforcement) and because it eliminates the craving for nicotine (negative reinforcement). In other cases, reinforcement can be both positive and negative. On a hot day a cool breeze could be seen as a positive reinforcer (because it brings in cool air) or a negative reinforcer (because it removes hot air). A child who is grounded after fighting with a sibling (positive punishment) or who loses out on the opportunity to go to recess after getting a poor grade (negative punishment) is less likely to repeat these behaviors.Īlthough the distinction between reinforcement (which increases behavior) and punishment (which decreases it) is usually clear, in some cases it is difficult to determine whether a reinforcer is positive or negative. Positive punishment weakens a response by presenting something unpleasant after the response, whereas negative punishment weakens a response by reducing or removing something pleasant. ![]() Punishment, on the other hand, refers to any event that weakens or reduces the likelihood of a behavior. Reinforcement, either positive or negative, works by increasing the likelihood of a behavior.
