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. Finally, only reinforce the desired behavior. Shaping is often used in teaching a complex behavior or chain of behaviors. Skinner used shaping to teach pigeons not only such relatively simple behaviors as pecking a disk in a Skinner box, but also many unusual and entertaining behaviors, such as turning in circles, walking in figure eights, and even playing ping pong; the technique is commonly used by animal trainers today.
An important part of shaping is stimulus discrimination. This discrimination is also important in operant conditioning and in shaping behavior. They use shaping to help him master steps toward the goal. Instead of performing the entire task, they set up these steps and reinforce each step.
First, he cleans up one toy. Second, he cleans up five toys. Third, he chooses whether to pick up ten toys or put his books and clothes away. Fourth, he cleans up everything except two toys. Finally, he cleans his entire room. Rewards such as stickers, praise, money, toys, and more can be used to reinforce learning.
How did the rats learn to press the lever in the Skinner box? They were rewarded with food each time they pressed the lever. For animals, food would be an obvious reinforcer. What would be a good reinforce for humans? For your daughter Sydney, it was the promise of a toy if she cleaned her room. How about Joaquin, the soccer player? If you gave Joaquin a piece of candy every time he made a goal, you would be using a primary reinforcer.
Primary reinforcers are reinforcers that have innate reinforcing qualities. These kinds of reinforcers are not learned. Water, food, sleep, shelter, sex, and touch, among others, are primary reinforcers. Call for reinforcements! The bridge is in need of reinforcement.

Positive Reinforcement In an attempt to increase the likelihood of a behavior occurring in the future, an operant response is followed by the presentation of an appetitive stimulus.
Negative Reinforcement In an attempt to increase the likelihood of a behavior occurring in the future, an operant response is followed by the removal of an aversive stimulus. Reinforcer A behavior operant response is sometimes more likely to occur in the future as a result of the consequences that follow that behavior. Positive Reinforcer A positive reinforcer is an appetitive event whose presentation follows an operant response.
Negative Reinforcer A negative reinforcer is an aversive event whose removal follows an operant response.
