Shaping and Successive Approximations

Operant conditioning is learning that occurs based on the consequences of behavior and involve the learning of new actions. It commonly uses reinforcement and punishment to influence behavior. Reinforcement is anything that increases the desired behavior, while punishment is anything that decreases the undesired behavior. Additionally, there is both positive and negative types for reinforcement and punishment. Positive is when something pleasant is added, while negative is when something unpleasant is removed. For example, when your mom is nagging you to clean your room, and then you clean it, so she stops nagging; the nagging is the negative reinforcement because the stimulus is removed (nagging) to increase the desired behavior (cleaning your room).

One type of operant conditioning that is used is called shaping, which is how reinforcers guide behavior closer towards a desired behavior. This is how dogs are trained. Complex behaviors are able to be created through this technique. By using successive approximations, or “middle steps,” animals are able to be trained to do complex behaviors such as discriminating many types of objects and events.

I trained my dog, Hudson (pictured above), to play dead using shaping and successive approximations. I used a high-value treat as positive reinforcement when Hudson completed the desired behavior. We started by having him lay down from a standing position. This was easy because he had learned to lie down previously. Then we had him roll onto his back with his feet up. This was a little more challenging because it was not necessarily biologically predisposed to voluntarily lying on his back. This took about 2 days to get him to do correctly. Then we also taught him to “come alive” which was his release phase. This did not take long for him to learn. Through shaping and using in between steps to teach him, Hudson successfully learned to play dead and come alive!

 

Types of Learning

David Popkin

There are typically ways for people to learn through classical and operant conditioning. Classical conditioning is all about forming associations with a stimulus and a response. Operant conditioning works through reward, and consequence. The two types of consequences are called positive and negative punishment. Positive punishment means adding a negative consequence while negative punishment means taking away something enjoyed as a consequence. Positive reinforcement means adding a desirable reward while negative consequence is when a negative consequence is taken away. Rewards can also be given at different times. The terms to describe these times are fixed interval, variable interval, fixed ratio, and variable ratio. Fixed interval is when is when after a certain amount of time has passed a reward is given. Variable interval is when the amount of time between rewards are varied. Fixed ratio is when after performing the desired amount of behaviors a reward is given. Variable ratio is when a reward is given after different amount of rewards. Operant and Classical conditioning are both effective ways of learning

My parents were able to use operant conditioning in order to get me to do chores. Every week I would do all the chores my parents told me to do because I knew a reward would come. The reward would come at a fixed interval. Every Sunday I would receive my allowance and then the cycle would restart. This system of behavior followed by reward is a perfect example of operant conditioning. I have also used classical conditioning throughout my life without even realizing it. When my dogs were puppies I was very motivated to train them. I figured out that I had to associate the word sit with a treat. Whenever they sat down after I gave the command the puppies would get a treat. Soon I didn’t have to give them a treat but usually do so the behavior does not go extinct. It took many repetitions to teach them a simple trick but it was effective.
