Here is a brief video of Skinner’s pigeons playing ping pong. It’s important to be aware of some of the drawbacks in using physical punishment on children. Second, the length of the time-out is important. Finally, only reinforce the desired behavior. As technical parlance, positive refers to adding a factor while negative refers to removing a factor. How about Joaquin, the soccer player? In discussing operant conditioning, we use several everyday words—positive, negative, reinforcement, and punishment—in a specialized manner. Jerome quickly cleans his room because he wants a new art set. A secondary reinforcer has no inherent value and only has reinforcing qualities when linked with a primary reinforcer. Parents and teachers often use behavior modification to change a child’s behavior. In this case, a stimulus (the toy) is removed in order to decrease the behavior. The Difference Between Positive And Negative Reinforcement. Reinforcement can be positive or negative, and punishment can also be positive or negative. Some teachers and parents create a sticker chart, in which several behaviors are listed (Figure 1). Let’s consider parents whose goal is to have their child learn to clean his room. Riders apply pressure—by pulling the reins or squeezing their legs—and then remove the pressure when the horse performs the desired behavior, such as turning or speeding up. Negative- Remove aversive stimulus which increases behavior in future Positive- Give a wanted stimulus to increase behavior in the future. For example, say that Sophia and her brother Mario are playing with building blocks. An important part of shaping is stimulus discrimination. Positive and negative punishment, generally speaking, is the concept of adding certain unfavorable consequence or depriving the individual of certain favored item or advantage, in order to decrease the behavior. Second, punishment may cause children to become more aggressive and prone to antisocial behavior and delinquency (Gershoff, 2002). You remove Sophia from the room for a few minutes. Recall Pavlov’s dogs—he trained them to respond to the tone of a bell, and not to similar tones or sounds. The difference between them is that reinforcement aims to increase target behavior while punishment aims to decrease behavior. Chances are he won’t repeat this behavior. BF Skinner Foundation - Pigeon Ping Pong Clip. In the classroom, the teacher can reinforce a wide range of behaviors, from students raising their hands, to walking quietly in the hall, to turning in their homework. If Skinner were alive today, he would probably think this was a great idea. Sophia throws some blocks at her brother, so you give her a warning that she will go to time-out if she does it again. Still confused? Next, begin to reinforce the response that even more closely resembles the desired behavior. Positive punishment involves adding or introducing an unpleasant stimulus to stop the action or behavior. Because of the negative side effects of punishment (in the traditional sense, i.e. Reinforcement means you are increasing a behavior, and punishment means you are decreasing a behavior. Modification and adaptation, addition of Big Bang Learning example. A good example would be a child jumping on the bed who stops after being yelled at by an older sibling. positive vs. negative reinforcement. Positive punishment is adding an aversive stimulus to deter a behavior. Now let’s combine these four terms: positive reinforcement, negative reinforcement, positive punishment, and negative punishment (Table 1). For instance, positive can be adding something unpleasant resulting in unpleasant feelings, while negative can be removing something unpleasant resulting in pleasant feelings. Mom gives Mag additional chores for lying. Positive Reinforcement. Shaping is often used in teaching a complex behavior or chain of behaviors. In order for behavior modification to be effective, the reinforcement needs to be connected with the behavior; the reinforcement must matter to the child and be done consistently. When she comes back, she doesn’t throw blocks. They do not refer to the quality or impact of the punishment. Brandon may become fearful of the hitting, but he also may become fearful of the person who delivered the punishment—you, his parent. For example, you tell your five-year-old son, Jerome, that if he cleans his room, he will get a toy. But positive and negative do not represent the quality of the factor being added or removed. Shaping is needed because it is extremely unlikely that an organism will display anything but the simplest of behaviors spontaneously. The examples above describe what is referred to as positive reinforcement. It has been found that one of the most effective ways to increase achievement in school districts with below-average reading scores was to pay the children to read. While strategies like this are common today, in the past children were often subject to physical punishment, such as spanking. As against, in negative reinforcement, reduction or elimination of an unfavorable reinforcer, to increase the rate of response. Learning: Negative Reinforcement vs. Remember that in order for reinforcement to work, the organism must first display the behavior. What do you think about this program? It operates on the principle of negative punishment. A few minutes later, she throws more blocks at Mario. All punishers (positive or negative) decrease the likelihood of a behavioral response. All reinforcers (positive or negative) increase the likelihood of a behavioral response. The pressure is the negative stimulus that the horse wants to remove. Pleasure is also a primary reinforcer. Remember that reinforcement, even when it is negative, always increases a behavior. Second, he cleans up five toys. Remember, it is best to reinforce desired behaviors, rather than to use punishment. For example, a study by Cangi and Daly (2013) found that use of a token economy increased appropriate social behaviors and reduced inappropriate behaviors in a group of autistic school children. Mary’s tv time was cut by 20 minutes because she did not listen to her Mom. When the children in the study exhibited appropriate behavior (not hitting or pinching), they received a “quiet hands” token. Instead of rewarding only the target behavior, in shaping, we reward successive approximations of a target behavior. Let’s go back to Skinner’s rats again. For example, (a) a child might be playing on the playground with friends and push another child; (b) the child who misbehaved would then be removed from the activity for a short period of time. The person or animal learns that to not lose their favorable stimulus again, th… For most people, jumping in a cool lake on a very hot day would be reinforcing and the cool lake would be innately reinforcing—the water would cool the person off (a physical need), as well as provide pleasure.
