Wok badge: Sense perception Marco Symington

a 'berry' good play about two theories of reality.

Rest of the Group: Eduardo, Huy, and Jeremy

Start journal 2/6/17

we are doing a 5-7 minute presentation of the 5th TOK chapter, sense perception. As of right now we aren’t 100% sure what we are going to do, but we are either going to do a project based on theories of reality, or perceptual illusions. We will most likely be doing something interactive in this presentation, such as a questionnaire. Our group understands well that we are behind in our project’s progress, but we hope to work diligently and efficiently today so that when the lesson ends we will be much closer to ready to present next class period.

end of class journal 2/6/17

in this class period we learned a lot and developed our project a lot. Definitely a lot more than we did in previous classes. We finalized our idea of what we were going to do for the project, and that really opened up the way for us to move forward. it was hard to come to a decision, but when we did we started zooming through everything and coming to agreements on many more things. We now know exactly what we are going to do, what props we need, and what we need to do to accomplish these missing parts to the whole of this project. I believe our project will go very well and also that it is an interesting topic to explore regarding sense perception. I’m proud of what our table accomplished today.

Isaac Lidsky: How Can Going Blind Give You Vision?

This TED talk on how "going blind can give you vision" is thought provoking and insightful. It talks about Isaac and his condition and how it would leave him blind. He was devastated by this shocking news and looked at this situation very negatively, thinking he lost something that was so important to him. The fact that we diagnose people without vision as a disability shows readers and all audiences in general how much we rely on senses, especially sight for our everyday lives. In chapter 5 this is seen through theories of reality. Common sense realism relies majorly on sight. and without sight or any of the other senses, we lose an aspect of how we perceive the world. Common sense realism is a theory of reality that states that we view the world as it is, and not much more. A knower views the world through its simplicity and what it perceives through its five senses.

2/8/17 reflection journal

I’m very impressed with myself and the members of our group on this project. We ended up getting off to a very late start, as we couldn't decide what we should use for our project. We ended up having only about 1 hour to make our entire project, because of the very late decision, but in that hour we got TONS of work done. I applaud Eduardo for taking the lead role, and leading us. Earlier i wrote how my goal for this project was to have my lines better memorized, and i believe i did that. I was coherent with my speaking except for my last bit of talking, but i had read that off the script so i was okay in the end. We got a 23/25 which is a 92%, which i am pleased about. Another goal of mine for this presentation was to stay within the boundaries of 5-7 minutes because other classes told me that Mr. Morrison would get really mad if we passed that limit. I was so nervous we would go over the maximum until our presentation started. Then the feelings went to the exact opposite. I was scared we wouldn't hit the minimum of 5 minutes. When we finished we ended at 6:45 seconds, a near perfect time.I’m happy wiht hour the project turned out and i believe my group should be too.

2/10/17 reflection journal

i learned in these past few lessons a lot about myself and sense perception. I learned that sense perception although is very reliable, is not always as true as we believe it to be. In some cases, sense perception is not the optimal way to know, but it is usually the one we refer to at a first glance at something, such as a scenery, how you perceive the world through the senses.

SCRIPT FOR OUR PLAY

(documentation)

Marco- instructor, presenter

Eduardo- scientific realism

Jeremy and Huy- common sense realism

Lenses of Perception

Oreo scientific realism: -When I taste the Oreo, I’m getting a sweet taste, indicating the presence of carbohydrates. Just think about it, it’s a source of short-term energy. If they’re consumed in moderation, how can they be considered unhealthy…I mean, everything is technically organic, made from living atoms and comprising carbon.

Common sense- Don’t think of the oreo in terms of chemistry and biology, just think about the fact that they’re cookies. Sweetness indicates sugar, but I’ve learned from past experiences that added sugar is simply unhealthy and even addicting. I know that eating too many will hurt my diet and decrease my consumption of nutritious food.

Common sense 2- Come on, it’s a cookie. Since when was a processed chocolate cookie considered food for athletes right before practice?

Scientific realism- You might be right. Now that I combine my thinking with logic, it does make sense that Oreos aren’t all that great. I guess they can increase chances of diabetes, which I realize is a negative health repercussion. Thanks for helping me out here, I’ll try to avoid them as much as possible.

Wow, this strawberry is great. But dang it, we just agreed that this sugary sweet taste corresponds to unhealthy food and snacks.

Common sense- Strawberries are fruits, of course they’re healthy. They’re directly organic, no processed added sugar.

Common sense 2- A strawberry’s a strawberry, it’s a good food whichever way you see it. Other knowers have all told me the same.

Scientific realism- Each strawberry is comprised of the monosaccharide fructose, but with the help of insulin it’s stored the liver as glycogen for later use. This is starting to make sense, thanks for helping me out with my diet guys!

Optical illusion 1 is shown and described by teacher:

Common sense- These lines are definitely slanted, isn’t it so straightforward! My senses are delivering, are you telling me my eyes are lying?

Scientific realism-Remember interpretation is a huge part of perception. Here’s a ruler, those lines are straight for a fact, just measure them. You’ll see that to observe the reality to the best of our abilities, you must learn to view only the relevant lines and then make observations.

Common sense- Wow, that’s pretty solid evidence. This is just incredible, can’t believe it’s the reality.

Teacher- Here’s a box now, tell me if you guys see anything

Common sense- Well, there’s a gray box, with a gray color much lighter in the bottom portion.

Common sense- I mean, it’s a skillfully drawn box.

Scientific realism- Wait guys, this is another optical illusion. You see, by adding the bright strip in the middle, the continuity was disrupted and the contrast between light and dark gray on the bottom square is highlighted. Take out the line, the effect disappears.

You taught me great lessons with food, but sometimes being straightforward deceives the senses into false creations. Be careful.

Teacher Great class discussions. So today we learned common sense and scientific realism have benefits and limitations as the situation changes, showing how the theories of reality must work in conjunction, along with confirmation with reason and intuition, and other such WOKs. Therefore, we can agree that senses primary function is not to give image of reality, but to provide tools for survival.
