“WOK Badge: Sense Perception”
Expectations and its Effect on Sense Perception
Our Question: To what degree are sense perceptions altered by our expectations?
January 31, 2017
Today we were introduced to how the badge system would work. I think it's extremely interesting and in this way we will learn more about the WOK's and AOK's. I feel like this system will allows us to be more hands-on and based on experience the more I am involved, the more I understand. Our first WOK is Sense perception. Today in class I read most of the chapter and I feel like one of the topics that stood out to me the most is change blindness. Since our perception is identified as being selective we tend to not notice obvious changes in our environment and surroundings. We only focus on what we seem to be interested in or what seems to catch our attention. Another subtopic that I am interested in this chapter is perceptual illusions. I think it's quite interesting how perception can be divided into two elements which is sensation and interpretation. I feel like this WOK is going to be extremely interesting and I can't wait to start on my presentation.

Primary Aim: Our project will be an altered version on the McGurk effect. The McGurk effect can be found in the TOK textbook. Mack, Alex, Paschalis, and I started our project with the question, "To what degree are sense perceptions altered by our expectations?" Our questions was based on "What is the role of expectation or theory in sense perception?" Our aim was to show how our sense perception can be altered to a high degree because of different sense biases we hold. We will test this idea by using a Kahoot to show how our sense perception are not always reliable/accurate as our sense often confuse each other. The way we use our Kahoot to test this idea will be explained below.
What did you do today/What did you accomplish today?
Since I wasn't here last class I had to take the quiz on Sense Perception. After I took my quiz I went and got together with my group (Alex, Mack, and Paschalis). They started a bit on the project last class so at first I was extremely confused, but then they explained everything and got me back on track. We discussed how our presentation will be an altered version of the McGurk effect, which I really enjoyed since I was extremely interested about this effect. We spent about 5 minutes trying to figure out what our essential question would be, and we came up with, "“To what degree are sense perceptions altered by our expectations?" We then hypothesized that Sense Perceptions were easily altered by expectations. Since our presenation was an alteration of the McGurk effect we spent most of the class period playing around with many different vowel and consonant combinations. We settled on around 11 combinations that were effect most of the time, and we concluded that we would record video clips of Paschalis saying these sounds in order to test our hypothesis. For example one of our combinations were "Faw" and "Baw". For example Paschalis would be mouthing the word "Faw", while the playback would be of the word "Baw." If we were to hear the word "baw" with our eyes closed, we would most likely realize that the sound "baw" was being made. However when we see the mouth movement of the word "faw" while the sound "baw" is being played, your eyes begin to weigh in, and sometime overrule your eyes. Therefore one will hear the word "faw" when in reality the sound that is playing is the word "baw". This will show how sense perception is unreliable it can be altered by our expectations. We hope to test how we use our previous knowledge to fill the gaps in our surroundings without using too much brain power in order to analyze those sensations.
What do you need to do to finish?
Today we did finish a huge amount of our TOK presentation. We figured out our presentation and how we would present it so that it's under 7 minutes. We also assigned jobs so that everyone would cooperate and not one person would be doing all the work. We just have to work on our kahoot and also video tape the clips that will be used in the kahoot. Mack and I will have to come up with a script or key points that we will have to say before and after the quiz. The quiz should take around 3-4 so we will have to up with 3-4 minutes worth of talking.

what are your goals and aims for today’s presentation/project? (discuss at least your personal goal)
My goal is to further inform people about Sense Perception. I believe that since our presentation is more hands-on (since they will be the ones performing our experiment) people will have a greater understanding our aim on sense perception. I think that our group is extremely prepared. We went over our presentation last night to make sure that it could be presented to be the best of our abilities. The only drawback is that Paschali is not here and we weren't informed until this morning so we had to rearrange our presentation so that we wouldn't miss any significant information. Our aim is to show people how Sense Perception can be altered by expectations. In order words that Sense Perception especially when dealing with several senses (multi-modal sensations), are unreliable and subject to our biases gained through prior experiences. One personal goal is that I have trouble presenting in front of people. I usually like to have like a planned script so that I know what I have to say thought my presentation. For this presentation I want to improvise more and see were my thoughts take me. I know its going to be difficult, but I hope that it turns out well.
AFTER PRESENTATION (Reflection Journal)
I think today's presentation went extremely well. I asked my peers for feedback and they said that it was extremely organized and very informational. I think that our preparation for our presentation was worthwhile. The only thing that didn't go as planned is that since the internet wasn't working as well as it should have, it caused the videos in our Kahoot to buffer multiple times. This caused our presentation to go over seven minutes. Although this happened, we still were able to get our message across and further inform our peers on sense perception. Although Paschalis wasn't there I feel like our presentation ran smoothly. I think that him not being there in a way forced us to work even more as a group which I really enjoyed. I think that this WOK is extremely interesting. I always new that sense perception was important, but I really never understood why. Our presentation which was an altered version on the McGurk effect, showed me that sense perception can easily be altered due to our past experiences. It is incredible how our biases play a large role in the interpretation of the world around us, later affecting our sense perception. Our biases often impact how we perceive the world.

Today we went on a field trip and just sat outside to observe our surroundings. In my opinion this was extremely relaxing. I don't remember the last time I have just sat outside to look at the environment. I always find myself doing something and I never have the time to just sit and think about what I am doing. I think that this personally helped me reflect on myself. I learned that it is important to stop and just think. Below are things that I saw and heard during our field trip.
- I hear birds chirping.
- I see a silver car glistening in the sunlight.
- I see a rusty vehicle with a huge bump on its rear end.
- I see hundreds of acorns which reminds me of Ice Age.
- I see leaves dancing with the wind.
- I see trees some with leaves and some without.
- I see multiple houses painted with a light shade of brown.
- I see a huge tree infant of me with vibrant leaves and missing branches.
3 Knowledge ?'s
Can expectations alter what we perceive using our five senses?
To what extent is eye-witness reliable?To what extent is my sense perception a reliable way of knowing?
To what extent is sense perception a reliable way of knowing?
Please read my journal dated January 3, 2017, in order to see the process in which my group and I went through to make our presentation. Like stated before our presenation was an alteration of the McGurk effect therefore we spent most of one class period playing around with many different vowel and consonant combinations. We settled on around 11 combinations that were effective most of the time, and we concluded that we would record video clips of Paschalis saying these sounds in order to test our hypothesis. Our next task was trying to find out a way in which we could test our experiment. We already knew what we would test and our method but we weren't quite sure on what application or platform we would use to perform our experiment. We had this problem pondering in our heads for a while until one of our group members suggested Kahoot. Below I have showed you the combinations in which we thought were most effective and I have posted the video clips on the Kahoot. After we found the combinations we made a doc regarding who would do what and we also put out script in which we would be presenting on February 7. We worked on the document the weekend before our presentation. On presentation day we just brought our notes and a computer with the Kahoot and we were ready to go. The link to our document is below.
