Successive Approximations

About 67% of all US households have some sort of pet, whether it be a dog, cat, fish, or even a lizard. Out of these 85 million families sustaining animals, for about 12 years now, I have been included within this percentile. In my particular case, I have had two dogs, both Golden Retrievers, and like many have trained them in certain ways to perform special tasks. It starts out with name recognition, then housetraining, and any others that one might want to follow through with like sitting, laying down, or rolling over. For any pet owners out there, we all know this is not an easy task and requires immense amounts of patience and repetition. One way to make something like this easier for both the owner and the dog is a type of operant conditioning we learned about called shaping. The idea of shaping first came from B.F. Skinner who discovered this phenomenon while expanding upon Edward Thorndike’s view on operant conditioning. Shaping offers an easier way to teach animals to act as a desired behavior through a method of positive reinforcement of behavior patterns. This term can also be called successive approximation and has been known to train animals to discriminate many types of objects and events. Skinner tested this theory on rats by breaking down behaviors into small, achievable steps in order to get them to press a lever to release food. Skinner would reward the rats for each step closer to the desired behavior, even if it meant them just slightly getting closer to the lever. By using this method of operant conditioning, Skinner trained the rats to perform proper behavior while deterring improper behavior.

Just like Skinner did with his rats, I used the same method of shaping on my dogs to teach them proper behavior. The main tasks my family and I would focus when training them were talents like sitting, laying down, and rolling over, as well as normal operations like, housetraining. For the talents, I started with teaching my dogs to sit by pushing their behind to the ground while saying the word “sit”. I would do this a couple times before rewarding them with a treat. This became a repetitive process for a couple days until they finally got a hang of it and it became instinct for them. After this, I proceeded with the same actions to teach them how to lay down. I would start out with saying “sit” in which they would sit to make sure the behavior is instilled in them and then repeated the previous process. I would physically push them to the ground multiple times, without causing any harm don’t worry, and then reward with a treat. Once again, I repeated this for a couple days and then used the same process for rolling over until all three activities were implanted within their minds and they could perform them without the retrieval of any treats. As well, I used the same system of treats for housetraining. Whenever they would go to the bathroom in the house, no treat was rewarded and we would occasionally yell at them, but if they went to the bathroom outside, a treat was rewarded. Both dogs eventually began waiting by the front door whenever they would have to go to the bathroom and then expected a treat afterwards. The desired behavior became so repetitive that both dogs could be let outside alone, with no leash, and would wait by the door until let in expecting a treat in the end. Even though this may not be successful in all cases of animals or dogs, it was quite fascinating to me how this worked so well for my dogs that we could trust them outside with no leash or electric fence with no worries.

Memory

This blog post is dedicated to the fascination and phenomenon that is memory. Memory has always been something that has baffled my mind, but I took extreme notice and obsessed over it in middle school, but refused to look into it until now. I have always had a bad memory in my opinion, but I would always compare my memory to one of my closest friends in middle school. Since learning about memory in class, I have come to see that my memory when I was younger was most relatable to the topic of maintenance rehearsal. This means that I had to repeatedly read, see, or even hear about something multiple times in order to keep it in my working memory. There have been numerous times where I had read a short excerpt in a class in which I would have to explain what I had just read. No matter how short the excerpt was, I was not able to retain a single piece of information from the text in order to give just a quick synopsis of what was just placed in front of me. This caused me to reread the information three, four, maybe even five more times just so I could recall the information to someone else. With this being said, most of this information would go straight to my short-term memory, but the truth is our short-term only last about 20 seconds. So, by the time I would be finished reading something, I would have already forgot about it, ultimately relaying myself back to reading it once more. This idea of rehearsal increases our short-term memory by at least 30 more seconds giving myself enough time to recall, but short after that, most of the information is gone. However, during this process, very little information is retained in my long-term memory, which is one side-effect of maintenance rehearsal.

This was very frustrating, especially when one of your best friends had what appeared to be a photographic memory. His mind had the ability to read or see something once and later, he could recall everything he observed days after, or even weeks at times. This was something I could not even fathom, especially with my struggling memorization issues. When I finally talked to him about it, I learned that he did not have a photographic memory and in fact, a photographic memory does not exist in a sense. What he was doing was something we discussed in class called elaborative rehearsal. Clearly being in middle school he did not use this term, but what he described to me was exactly this. Instead of repeating himself, he would think about what was just taught to him and associated the new information he was trying to learn with information he already knew. With this technique, everything he learned was being easily transferred from his short-term memory to his long-term memory in such a meaningful way that lead him to have such a strong long-term memory. This type of semantic encoding shows how he was able to remember things for so long as this process required the brain to process the information in a more in-depth way than normally. From that point on, I stopped repeating things to myself and practiced this technique of memorization, in which it has helped me immensely.

Personal Experience with Neuropsychology

“The brain is one of the largest and most complex organs in the human body. The brain is made up many specialized areas working together as well as nearly 100 billion nerves that communicate in trillions of connections. “This is a phenomenon in itself that an organ no bigger than the size of a melon can control all the nerves in our body and tell us exactly what to do. Another phenomenon to discuss is how the brain operates at such a high successful rate each and every day, but the reality is the brain does have its deficiency’s. The study of Neuropsychology examines damage to the brain in certain areas. This damage deals with the relationship between cognitive, emotional, behavioral and brain functions. About half a year ago, I had an experience with brain damage in my family and got to experience Neuropsychology first hand.

During Easter weekend last year, my family came up to visit me as usual. We would go to church Sunday morning in Pasquerilla, and then have a nice Easter brunch at the Nittany Inn. On this particular Easter, my dad picked me up from my apartment and we went off to church, and everything seemed normal as I didn’t question anything. It was after church as we proceeded to go to brunch did my family notice a difference. When we got in the car, he started to repeatedly ask us “Where am I going?” and “Where am I?”. This wasn’t particularly too odd because normally dads will be dads and ask the same question over and over again just to mess around with you. But, then he asked my mom multiple times “Did we check out of the hotel?” after he clearly gave my mom the room keys to go check out. Along with this, he kept checking the back of the car to see if they were all packed not realizing that the trunk was filled and they were ready to go home. It only got worse as he mistook the pineapple on my plate for eggs, was not eating anything, and began getting up from his seat to walk around and just stare up at the ceiling blankly. It was at this point that my family and I knew something was definitely wrong. Fifteen minutes into brunch we left, and rushed to Nittany hospital. In Nittany hospital they put my dad into stroke alert and began performing tests on him. Luckily, my father did not have a full on stroke, but he did experience what is called Transient Global Amnesia. TGA is a sudden, temporary episode of memory loss and can often be associated with neurological conditions such as strokes or amnesia. The symptoms resided themselves within 24 hours, but their is still a portion of the day that my dad does not remember at all and for a slight second he could not even remember who I was. I think it is safe to say that we can classify Transient Global Amnesia as a study in Neuropsychology. Below is a link demonstrating more information on TGA as well as how the brain looks while undergoing this amnesia scare.

The image above shows the progression the brains takes as Transient Global Amnesia happens. Over time, blood vessels that head to the brain get clogged ultimately causing this neurological condition. The doctor showed us similar images to these and further explained how this cloggage messes up memory and some body motions.
