This day we learned what sense perception was and its connection to Theory of Knowledge. My group came up with practice quiz questions for this chapter. It's quite interesting to me that our senses play such a massive role in our knowledge. Everything we know comes to us from our senses. (Hearing, seeing, touching, etc ) We also learned that there might be other senses we use that we don´t recognise officially yet. In my opinion the way we perceive things is very important, and our surroundings play a massive role in our knowledge.

Today in class we took a quiz over the sense perception chapter which I required 2 tries to pass. When I passed the second one with a 10/10, I felt like I really understood the chapter. The class discussion was more helpful than reading the actual textbook to be honest. After taking the quiz, our presentation group debated on what we should do for our presentation, to ultimately earn our badges. My idea was to have volunteers taste different foods with their eyes closed and guess what it was. This would show the relationship between taste, smell and sight. Everybody would have recognized the foods with their eyesight, but could they do the same relying on their taste and smell? I think this experiment would test our sense perception, and show how vital our senses truly are.

Start of Class: Today we will focus on our sense perception presentation. We need to figure out what objects we need for the project, and who will bring what. We will bring them in on the presentation day. I think that today we need to focus on making our presentation and connecting our activity to what we are actually learning, sense perception. Real world examples and using Theory of Knowledge terms will help us with our presentation, as they will put what we mean into context. Our presentation will examine the relationship between sight, taste, and smell. To be more exact, how our brain's interpretation of gustatory and olfactory information is affected by lack of visual information.

End of Class: Today in class we learned how to condense a broad theme into a concise essential question. Our essential question was: ¨To what extent can we trust our senses of taste and smell without sight?¨ This class period was one of our most productive. We almost finished all the planning necessary for our presentation. All that is left to do is for everybody to deliver their promises. In this case, the promises are to prepare for the class presentation and bring our assigned items.

Knowledge Questions

How can we know if our senses are reliable?

There is no way to know if our senses are reliable. The way we perceive things is affected by how our brain interprets it. We all sense the same things, but how we interpret it is unique to everybody.

To what extent do you agree with the following claim: “All knowledge begins with sense perception”?

I mostly agree with this claim. While most knowledge begins with sense perception, there is also the factor of memory. We know some things thanks to our experiences we've already had. However, in cases where the knowledge is something we haven´t learned before, the start is to sense something. From there, you gain the knowledge.

The Experiment

What we used

Cherrios
Dried Mango
Rice Cakes
Carrot
Apple Sauce
Experiment

Hypothesis: People will have a hard time guessing the food without their sense of sight.

Procedure: We blindfolded volunteers and gave them food to smell and then eat. They would then guess what the food was.

Conclusion: People had a very hard time guessing the food because of their impaired senses. the fact that they were missing their sense of sight meant they relied on smell and taste.

Reflections

This was a great project overall. We had a solid, interesting, testable essential question. However, we passed the seven minute maximum. Nevertheless, the project was very beneficial to trying to learn and understand the Way of Knowledge of sense perception. We started off reading a chapter and trying to understand the main concepts and vocabulary terms and ended with an original experiment that provided an interesting approach to a knowledge question dealing with sense perception.. After reading the chapter and passing the quiz, our group had a much clearer idea of what sense perception really was. After that, we focused on formulating an experiment to where it provides us with the knowledge we seek (our essential question). Our biggest problem was figuring out what we could test that would involve these senses. Once we made that choice, the project experience improved at an exponential rate. Every improvement we made lead to even better ones. Everyone in the group made contributions and the project was a success. This project made me realize on how dependent our senses are on each other. they are all connected. It´s not really five senses, but a network of different senses. Working together, these senses create our perception of the world. This project was entertaining to complete and I learned a lot, not only about sense perception, but also about planning and working within a group.

Elective Reading

This TED Talk is about Isaac Lidsky. This man lost his sight at age 25 and speaks about how he turned this unfortunate situation into a blessing for him. He mentions that losing his eyesight taught him that he is in control of his own reality. While watching this TED Talk, I realized that our brain is nothing but a neural computer that receives, stores information, and interprets it with several factors involved. Sight is an illusion. Your brain creates an image of what you physically see from the light rays our eyes perceive. However, our brain also associates everything with a specific emotion and reaction. Lidsky says, "What you see can impact how you feel, and how you feel can literally impact what you see." What he means is that we don´t ¨see¨ objectively. The visual data that we sense with our eyes is objective. However, the way our brain interprets visual data is completely subjective. There are many factors involved such as memory, age, gender, etc. We don't see a universal truth, but the truth our brain creates from what it gets. Isaac states that what we see is not the universal truth or objective reality, but rather what we see is a unique and personal reality that is constructed completely by our brain. Isaac´s truth is what he senses with his other senses, "You create your own reality and you believe it." Without eyesight, Isaac is able to ¨see¨ the world at its actual state without the impact of his brain affecting the image. This TED talk was very interesting to me as it showed me the power of our senses and how much they truly affect the world we perceive around us.

Extension Proposal

I chose this as my extension proposal source because of its relevance to the chapter on sense perception. It´s also a good source we can add to the elective reading list we use now. Our presentation essential question was ¨To what extent can we trust our senses of taste and smell without sight?¨. This source dealt with that same idea, the idea of ¨How can we know if our senses are reliable?¨ Throughout this TED talk, Donald Hoffman attempts to answer this. He is an expert in cognitive science, and truly understands how the brain works. He shows us how the brain interprets our sensory data to construct our own personal reality. I really enjoyed this TED talk and found it interesting and relevant as a source because of the numerous examples Hoffman provides of how the brain interprets data to shape our world.
