Memory Deterioration is the process of memories deteriorating by means of aging, injuries and accidents, or brain diseases. But why do these causes make our memories worse? Is it the only cause? Many people try to come up with only one conclusion or two, but there are actually many reasons for why our memories deteriorate, and there is usually not just one hypotheses explaining this. This is important for studying the effects of memory on humans/animals, also for studying certain diseases such as Alzheimer's, Parkinson's, and many other brain problems relating to memory. In real life, one America acquires Alzheimer's disease every 72 seconds. But why? Is it only because we age? As we take a look at this video, it explains how Alzheimer's is another progressive neuro-degenerative disease, through the views of the patients, doctors, and results.

As we can once again tell, it is evident that the actually cause of Alzheimer's disease hasn't been established yet. Will we ever know the cause? There are causes such as neurofibrillary tangles which create the loss of synapses, but this isn't the cause of memory deterioration, because correlation doesn't equal causation. There could've been an alternative reason to why patients that have those diseases, lose memory. This could be because with a loss of synapses comes a death and deterioration of acetylcholine neurons.
Some common myths of Alzheimer's is that "Memory loss is a natural part of aging." Although this can be seen to be true by many, it has not yet been scientifically proven,and the research still needs to be addressed. Also, there are people in real life that don't lose much of their memory as their age(but we should still keep in mind that their memory isn't always as reliable as it should be).

Freud's dream protection theory states many things about dreams such as fulfillment theories, wish fulfillment, and dreams being the protectors of sleep. But are these theories correct? Have these claims been disproved? The answer is yes, and they are false or are only closely true to what they're trying to interpret. Despite the validity of this theory, it is important because dreams have a lot to do with our daily lives. And by that, I mean that most people interpret their dreams without thinking scientifically. That's important because it can lead people to believe that their dreams have meaningful relations to their life. It's not true that it doesn't have any meaning at all, it's just that scientific evidence, and biological psychology studies ( such as activation-synthesis theory), has proved to show that most dreams don't depict hidden messages, but very obvious messages. If we take a look at this video, at the end of it is a man who says he saw a dream about a bloody man running through the church where him and his mom were at the time. He woke up and 5 days later his mother died.

Can we say that this had to be because he dreamed of a bloody man? What does the bloody man have to do with his mom dying? We have to think of the scientific principle " Correlation Vs. Causation". We can think of many instances where we had people being involved in a scary dream, and there are many people who die. We can think of it more like a coincidence. This is important to think about, because things like this can factor in everyone's life, and can affect it drastically. To think scientifically about it, we can avoid ignorant decisions that we make, and we can think about things that actually make sense. If we don't, we might just end up believing the wrong things that can dramatically alter our lives ( such as having a dreams that can bias our decisions and have a negative effect in our lives).
This picture symbolizes Lucid dreaming. I find this interesting, because I was unable to find articles or research that relates Lucid dreaming to dream protection theory. It makes me question if our dreams actually do have meaning if we lucid dream. Or if our decisions that we make while lucid dreaming depict our personality, daily decisions, life choices, etc... because that would mean we actually do have control of our dreams, and that what we do could effect our real life decisions, despite it being a dream ( because you can control a dream while lucid dreaming).

Synesthesia can be defined simply as the mixing of senses within a individual. By mixing, I mean interchanging, or you can think of it as replacing. It's when people experience crossing sensations such as having the ability to taste colors, or being able to see colors when they hear sounds. This can vary depending on the condition and severity of Synesthesia within a person. For example, if a person looks at this picture with synesthesia, they will see colors for the numbers, and can easily differentiate the 5 and the 2.


This condition is very important, because it can explain many different theories and concepts, such as the process of Sensation and Perception. To simplify things, Sensation picks up what we receive from our environments, and Perception is how our brain processes that information. But what about Synesthesia? Why do we feel cold when we see something so irrelevant such as a table? Why do we see the number 5 and think of a color? There's a neurological explanation, "When you were born, you had far more brain cells than you needed. A period of pruning happens where only the connections and brains cells you need and use survive. This is a normal and vital part of all mammals' early development. " This is important to understand, because we can use this information to help solve this kind of problem, and it could possibly be a link to other neurological problems. As we see in this link, , this young adult interchanges color with shapes and different words, letters, and even numbers! He states that it is a "feeling thing". This impacts his daily life because everything he does such as play music, it reminds him of color. This could help him remember things more clearly, or simply play better music with more feeling. But should this be cured? Is there a way to cure this? This is a good example of an article explaining synesthesia that can be disproved, If you look at the video, it's promoting inattentional blindness, it's not a test showing that you have synesthesia. If that was the case, then most people would have synesthesia, and the ratio for people who have synesthesia wouldn't be 1/2500, it would be higher... This promotes the principle Occam's Razor, and Ruling out Rival Hypothesis, because there's a simpler explanation, and the claim was ruled out by scientific evidence ( the ratio of synesthetic people). In this case, ruling out rival hypothesis is the most important rule of principle to follow.
