Some children will need a more specific reinforcer, for example, an arm squeeze or break, after minutes of good behavior. When specific, individualized reinforcement schedules are designed, behavior can change in the desired direction. You might see behavior change, or you might not.
Click to Tweet! Great article! I get asked the difference between reinforcers and rewards all the time at my center Le Chemin ABA and will share your article with families and professionals.
We want to make sure that what we offer our learners is truly reinforcing see our post on Reinforcers versus Rewards. One way to do this is to offer choice. Peggy says:. November 22, at pm.

Our paychecks are rewards, as are high grades and acceptance into our preferred school. Positive reinforcement as a learning tool is extremely effective. 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. The result was a significant increase in reading comprehension Fryer, What do you think about this program?
If Skinner were alive today, he would probably think this was a great idea. In fact, in addition to the Skinner box, he also invented what he called a teaching machine that was designed to reward small steps in learning Skinner, —an early forerunner of computer-assisted learning. If students answered questions correctly, they received immediate positive reinforcement and could continue; if they answered incorrectly, they did not receive any reinforcement. The idea was that students would spend additional time studying the material to increase their chance of being reinforced the next time Skinner, In negative reinforcement , an undesirable stimulus is removed to increase a behavior.
The annoying sound stops when you exhibit the desired behavior, increasing the likelihood that you will buckle up in the future. Negative reinforcement is also used frequently in horse training. 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.
The pressure is the negative stimulus that the horse wants to remove. Watch this clip from The Big Bang Theory to see Sheldon Cooper explain the commonly confused terms of negative reinforcement and punishment.
Many people confuse negative reinforcement with punishment in operant conditioning, but they are two very different mechanisms. Remember that reinforcement, even when it is negative, always increases a behavior. In contrast, punishment always decreases a behavior. In positive punishment, you add an undesirable stimulus to decrease a behavior. An example of positive punishment is scolding a student to get the student to stop texting in class. In this case, a stimulus the reprimand is added in order to decrease the behavior texting in class.
In negative punishment , you remove a pleasant stimulus to decrease a behavior. For example, when a child misbehaves, a parent can take away a favorite toy. In this case, a stimulus the toy is removed in order to decrease the behavior. Punishment, especially when it is immediate, is one way to decrease undesirable behavior.
For example, imagine your four year-old son, Brandon, hit his younger brother. While strategies like this are common today, in the past children were often subject to physical punishment, such as spanking.
First, punishment may teach fear. Brandon may become fearful of the hitting, but he also may become fearful of the person who delivered the punishment—you, his parent. Similarly, children who are punished by teachers may come to fear the teacher and try to avoid school Gershoff et al.
Consequently, most schools in the United States have banned corporal punishment. Second, punishment may cause children to become more aggressive and prone to antisocial behavior and delinquency Gershoff, They see their parents resort to spanking when they become angry and frustrated, so, in turn, they may act out this same behavior when they become angry and frustrated.
While positive punishment can be effective in some cases, Skinner suggested that the use of punishment should be weighed against the possible negative effects. Make sure you understand the distinction between negative reinforcement and punishment in the following video:.
Still confused? Watch the following short clip for another example and explanation of positive and negative reinforcement as well as positive and negative punishment. In his operant conditioning experiments, Skinner often used an approach called shaping.
Instead of rewarding only the target behavior, in shaping , we reward successive approximations of a target behavior. Why is shaping needed? Remember that in order for reinforcement to work, the organism must first display the behavior. Shaping is needed because it is extremely unlikely that an organism will display anything but the simplest of behaviors spontaneously.
In shaping, behaviors are broken down into many small, achievable steps. The specific steps used in the process are the following: Reinforce any response that resembles the desired behavior. Then reinforce the response that more closely resembles the desired behavior.
You will no longer reinforce the previously reinforced response. Next, begin to reinforce the response that even more closely resembles the desired behavior. Continue to reinforce closer and closer approximations of the desired behavior.
