Conditioning – Operant Vs. Classical – Training Dogs

During this unit in psychology we learned about two different types of conditioning. The two types we discussed in class were classical conditioning and operant conditioning. Although these two types of conditioning seem to get mixed up a lot, they are two completely different things.

Classical conditioning is a type of learning that has to do with learning with the association of a stimulus. There are four factors to classical conditioning; unconditioned stimulus, unconditioned response, conditioned stimulus and conditioned response. The unconditioned stimulus is what naturally causes a response, the example we used in class with the food that was given to the dog. The unconditioned response is what naturally occurs, the example from class was the salivation. The conditioned stimulus normally would have nothing to do with the stimulus but it is connected to the trigger, during class the example was the tone. Finally the conditioned response is what is learned. Classical conditioning follows these four concepts that are distinguished by a behavior being learned through the process.

The other type of conditioning is called operant conditioning. Operant conditioning is when an association is made between the result of an event and the behavior that caused the result. This is different from classical conditioning because due to classical conditioning you have no control over what is being learned. Operant conditioning follows the idea that if you do well, you will receive a reward; therefore you will always do better and try hard in order to receive that reward.

A part of operant conditioning that is very common deals with shaping, which when a person (or reinforcer) reinforces and guides the behavior to produce a favorable outcome or behavior. I have used this concept many times with my dogs at home. When we first got our dogs they were all little puppies, and had no clue how to do anything except bark at all hours of the night and pee on the carpet when no one was looking. My siblings and I made it our goal to train them to do cool tricks and listen to us when we gave them commands. In order to get the dogs to learn the tricks and commands we wanted them to learn we used shaping and operant conditioning. When teaching them to shake our hand we would make them sit, and give them a treat and then they learned that when they would sit they would get a treat. After that we started saying paw, and would tap their paw in order for them to place it in one of our hands. When their paw was in our hands, we would give them a treat. They once again realized that once they did these actions they would get a treat. After a lot of practice and a lot of time, the dogs were able to do more then just bark and break all of their toys. Operant conditioning was used to teach them how to do their tricks. At the time I did not know there was a name for the process that was going on, but after discussing it in class I realized that there is a name for training dogs to do tricks by rewarding them as they excel in what they are doing.

Monocular Cues – Motion Parallax

As part of the second unit in the class we discussed vision and many different aspects involved with our vision. One subject we discussed that I seemed to find very interesting was the discussion about Monocular Cues. Monocular Cues are used to help perceive depth by only using one eye. There are many types of cues for example; relative size, interposition, aerial perspective, linear perspective, texture gradient, and motion parallax. Artists use these cues to help portray depth in their work and create a more realistic creation. Each of these cues helps portray depth in different ways and they are all used and perceived in many different ways all of the time.

Relative sized is used when two or more objects are being compared. The one that is smaller, therefore casting a smaller image on the retina is seen and perceived as farther away then the object that is bigger. Interposition, which is also referred to, as occlusion is when one object is in front of or blocking the other object, meaning that the object being blocked is behind that is blocking it. Another cue we discussed was linear perspective, which is when parallel lines are used to converge in the distance. This can be seen a lot when creating roads or long distances in paintings.  People often get this mixed up with convergence but they are not the same thing and should not be mixed up. One other cue is motion parallax, which for me seems to be the most common and easy to understand.

Motion parallax is when an object closer to you tends to move at a speed much faster than an object that is farther away. When I was coming back home for spring break and was looking out the window I seemed to notice this a lot. When I was looking directly out the window right next to the bus the area on the ground made it seem like we were moving at such an great speed. However, when I looked beyond what was just in front of me and into the distance I did not feel as if we were still moving with that same speed. Everything that was much farther away was moving with a slower speed compared to the ground right next to the bus. Motion parallax is used to determine absolute depth perception and helps display the discrepancy in motion of near objects and of objects that are much farther away.

Laboratory and Naturalistic Observations

Today laboratory observations are very common while trying to understand the behavior of a person and even in some cases of an animal. Along with laboratory observations, naturalistic observations can also be made. The two different observations help researchers find out what is wrong with a specific person or animal and what could possibly be causing that. Observations allow researchers to gather their information, and form conclusions in order to help someone out. Laboratory and naturalistic observations are both successful in seeking out the information needed, however they both contain a number of advantages and disadvantages making them more appealing in certain conditions.

Naturalistic observation allows the patient to be very comfortable in their setting and eliminates the fear of the patient being uncomfortable. Natural settings allow the patient to act natural, and have a great possibility of matching up with the real life behavior of the person. However a disadvantage is that when someone knows they are being observed they can change the results of the study without noticing. If someone knows they are being watched it can alter their behavior and change the results, which has the potential to possibly mess up the information gathered by the researchers.

On the other had laboratory observations occur in a laboratory because special equipment might be needed to perform the experiment and it might be hard to provide that equipment in a natural setting. Advantages of observations taken from a laboratory include a much more controlled setting. Being in a laboratory, the researchers are able to control everything that is happening and can minimize any outside influences. Another advantage to this kind of observation is the use of specialized equipment; it can help produce results that would not be able to be observed outside of a laboratory. However, being observed in a laboratory can be very uncomfortable to some people. When a patient knows they are being observed it can be very hard for them to focus and can possibly alter the results.

My friend recently has been having problems when she is sleeping and doctors have a feeling that she stops breathing in her sleep. While she was explaining all of this to me she said she was scared to go in for testing. Ironically we had just discussed behavioral observations in class, and I knew why she was so nervous. She had said that they want to watch her sleep, in order to determine if she does indeed stop breathing while she is sleeping. I knew she was going to feel uncomfortable since she would be sleeping in a new environment but I kept reinforcing her that they only want to find out what is wrong with her. Although she was very scared and nervous for the testing to be done, she knew that it needed to be done for them to figure out what is wrong with her when she is sleeping.

I thought it was very interesting that she had mentioned this right after we had learned about it. Everyday people are undergoing observational studies in order to figure out what could possibly be wrong with them, if anything is wrong. A laboratory observation does have many advantages however, for some people it can be very unpleasing and very nerve-racking. At the end of the day, the process of being observed is worth it because researchers and specialists gather the information needed to help figure out what is wrong with someone.
