I always thought perception meant a point of view or a perspective of somebody. But today I was open to another meaning of perception. In TOK, it refers to how we gain knowledge through our five senses: sight. smell, taste, hearing, and touch. In this, I also learned that there are other things such as sensation and interpretation. Sensation meaning it is given by the world and interpretation is given through our minds. Sensation is the things around us but everybody has a different interpretation of things. Not everybody will have the same interpretation of an image that they see. Our eyes are all different and we might be able to see something that other people may not see due to their difference in eye sight power.

believe that a good way to show to the audience an example of sense perception is by playing an investigation game where we blind fold people and give them objects to feel so they will be able to tell us what kinds of ways the idea can be interpreted. We can blind fold every person and give them all the same object and they can describe it to us and since everyone has a different sense perception we will poll which object is mainly seen with common-sense perception, scientific perception, or empiricism. Today I learned about the different theories of sense perception. this includes common-sense realism, scientific realism and phenomelism. There are also different ways of perceiving objects such as the visual ground method.

The things that I need to accomplish with my group today is that we need more of a foundation on what we are supposed to do for our experiment and we also need to make a clear hypothesis on it. I learned that we don't have a solid topic that is relevant to what we are supposed to do. So now we need to reevaluate our question and change it so that it will fit with what we need to achieve for the WOK badge. Problems that we have faced include the fact that our questions
Feb 7 journal entry:
Today we are presenting our projects for TOK and I would like to achieve a sense of accomplishment after this class. I would like to know that my group and I have shown to our class a sense of interest for out subject also to teach them something about sense perception in a manner that is both fun and educational.
If we were to do our experiment differently we should have done an experiment relating to our question such as visual grouping or visual grounding. Our question had no correlation to our experiment and I believe that we had no time to do this. We should have been given more time.
Elective Reading Journal
In this Ted Talk, David Linden states that touch is the most disregarded sense. He believes that touch is one of the most important of the five senses and individuals use it everyday as a form of communication. For example, people often use the phrase " I feel..." or "I am touched by..." when they are actually not feeling anything physically but feel something emotionally. This is scientific proof to show that humans are made to be emotional human beings and that they feel many things without physically feeling things. This opened my eyes to the senses that we have. I always believed that sight and hearing were the most important senses. But after I watched this TED Talk, I believe that sight and touch are the most used in an individual.
TED Talk: How Can Going Blind Give You Vision?
Isaac Lidsky lost his eyesight when he was 25. At first he thought that it was curse, but now he is saying that losing his eyesight was a blessing. It made him realize that he could create his own reality. Lidsky states that an individual uses their sense perception in regards to their prior knowledge on their surroundings. So when one of an individual's senses are taken away, they are substituted with a different way of perceiving things due to their modification in sense perception. With his lack of vision, he states that he can create his own reality and believe it. He is in charge of what he sees. Even though he does not actually see things, he imagines what he sees, and what he imagines, he believes is real. I have always wondered how people with visual impairment work. And with this TED Talk, I now understand that people who lack one sense will substitute it with another sense.
For my WOK badge presentation, my group and I conducted a experiment to test how reliable our sense of touch is with lack of vision. Our hypothesis for this experiment was that "the lack of vision will cause the subjects to have different interpretations of the object they are touching due to a modification in their sense perception". After we conducted our experiment to the class, we did not get the reaction from the participants that we were looking for. What we had hoped for was that at least one person who touched the spaghetti blindfolded would think that it was another object either than spaghetti. We had two items we wanted them to touch blindfolded. A fuzzy key chain and cooked spaghetti. But because of our time crunch, we were unable to present all our objects to our participants. Our results were that everyone who touched the spaghetti knew it was spaghetti.
If we were to do this project again and make it better, I believe that we would ask people outside of the class and create a video instead of doing it inside the classroom wasting time. Our experiment was also quite unorganized and we had people sprawled out everywhere. Our question also did not specifically relate to what our experiment was. I think that we should have narrowed it down again or chose an easier question that we could conduct a closely related experiment to.
How reliable is the knowledge provided by our senses?
This knowledge question is relevant because people should understand that our senses are not as reliable as we think they are. Sometimes the way we see, hear or touch things are different than what they really are. For example there have been many instances where people would perceive something as another because of their modification in sense perception. Everyone sees things differently, nobody can see the same thing. This is a significant knowledge question that should be added to the list because the main topic we are talking about is sense perception. And when we talk about sense perception we must also talk about how our senses can throw us off.
To answer this question, we can rely on our senses to an extent, but we cannot solely rely on it because they are not always correct. For example, if you are looking at a distorted image, your brain uses visual grouping to try and link the shapes together to make something out of it.
