Do we hear what is really there or what we “want” to hear? The McGurk Effect is an example of an auditory illusion.Tags: Sense Perception, Ways of Knowing
The following episodes relate to the 'Sense Perception' Category
Ifound two videos which illustrate the importance of emotions and perception in understanding statistics. In the first video, the speaker Hans Rosling uses animated graphs to visualize the development of different countries. It is a powerful illustration on how a visual representation (sense perception!) of numbers in the form of colorful dots greatly helps in understanding statistics. Tables with numbers alone are too difficult to perceive. Rosling’s computer program makes these numbers accessible.
The second video is quite remarkable as well. It links the areas of knowledge arts, statistics (math), with the ways of knowing sense perception and emotions. The photographer Chris Jordan wants to create impact by visualizing very large numbers and thus causing emotional involvement. We people often do not want to act to improve our environment, for example, becasue the numbers and statistics that we have available are simply to abstract and too large. What does it mean, when we say that we use millions of paper cups every day? How much is a million? Is this a lot? How much is a lot? Chris Jordan’s artwork helps us in perceiving these numbers, this way causing emotional involvement and creating an incentive to act.All Articles, Areas of Knowledge, Arts, Arts, Emotion / Intuition, emotions, graphs, linking, Linking Questions, math, Mathematics, Sense Perception, speeches, statistics, ted, Videos, Videos, Ways of Knowing
Linking the different Areas of Knowledge (AOK) with different Ways of Knowing (WOK) can be quite challenging at times. I now attempted to link History with Language, Logics, Emotion and Sense Perception.
History and Language:
- Does the way (the language) that certain historical events are presented in history books influence the way that the reader understands these events?
- What role does loaded language play when talking about historical events?
- What role do connotation and denotation play when talking about historical events?
- How can language introduce bias into historical accounts?
- How does language help or hinder the interpretation of historical facts?
So, you are now sitting in front of your computer reading this very post about the Ways of Knowing. How do you know that? Honestly! How do you know that you are reading this text right now? Is it because someone told you? Of course not. You know it because your senses tell you so. You can read the text with your eyes (vision), you hear the sound of the computer fan humming (hearing), and you feel that you are sitting on a chair (touch).
Philosophers have identified these four ways of knowing: Sense Perception, Language, Emotion/intuition and Logics/Reason. Pick one fact that you know and ask yourself what the sources of this piece of knowledge are. From where do you know it? You will soon discover that it is possible to trace you knowledge back to one of these four Ways of Knowing. Let’s start with a little example: “I know that atoms exist”. How do you know it? Have you ever seen, heard or felt atoms before? I can hardly imagine. Sense perception is therefore an unlikely source. Do you intuitively and emotionally feel their existence? Hopefully not! The most likely source of this knowledge is that someone told, most probably a teacher, you or that you read about them. The source of this knowledge is therefore language.

The idea that that the language that we use can influence the way that we think is nothing new. According to the Sapir-Whorf-Hypothesis (also known as linguistic relativity) language does not only reflect our way of thinking, but is also able to shape it. This hypothesis became known in the 1950s. People from different cultures and languages view the world differently and organize their reality differently. The way that they think is influenced by the grammar and vocabulary of their language. To bring it directly to the point: there are certain thoughts and ideas that can only be thought in a particular language. These ideas do not exist in other languages. In this episode I’d like to give you several examples that illustrate this point. Continue reading »Tags: All Articles, Language, Language, Perception, Sense Perception, Ways of Knowing
When I was younger, in my teens, I started to discover my love for the sciences. I was fascinated by Biology and Physics and I think I must have driven my teachers crazy with my constant request for “proofs” and evidence. I liked science so much that I even included chemical formulas in my literature essays. Instead of saying “The water waves are gently moving in the sunset.” I’d write “Waves made of H2O are gently moving in the solar spectrum.” My English teacher then responded, “Don’t forget about the H2SO4 (sulfuric acid) which is dissolved as well!”. An then I didn’t feel as bad about the bad mark on the test anymore… Now I am teacher myself and occasionally I meet some students who remind me very much of myself. They are constantly confronting me with the words “How do you know that?” – always eager for empirical, scientific evidence. They want to see things before they believe it. They want formulas. They want cause and effect relationships. Without having been aware of it, I myself as well as my students, were followers of a certain philosophical school. We were “Positivists”.

I like to keep myself informed and I therefore like to read newspapers. Now with the internet being so widespread, I do not buy newspapers anymore, but rather visit my favorite newspapers online. Usually I start out with the computer news to keep myself updated on new products and developments, followed by science (deep in my heart I am a scientist, after all!) and politics and economics. The sports section I usually skip, I have to admit to you that I am not very competent in this particular area of knowledge. But I do read the sports section during the Olympics.

In this edition we will have a look at the concept of determinism. In a deterministic system the initial conditions of the system determine the future behavior of the system. The behavior of both a falling apple and a rolling die depend on the initial conditions. Even the same laws of physics apply, namely classical mechanics. Both falling apple and the rolling dice are deterministic systems. But I am able to calculate the landing position of a falling apple, but I am not able to calculate the result of a die roll. Why? How are these two examples different? Why does the die seem to behave according to chance, but not a falling apple? A rolling die is chaotic and it is unpredictable, even though it is deterministic. Even if we know all the physical laws and the starting conditions of a system, it is still not possible to predict the future behavior of chaotic systems.

In this edition of TOK-TALK we will explore if it is in principle possible to measure anything accurately. How does a measurement change the value of that what you want to measure? Listen to find out!
Here in front of me, I have a cup of hot water, and over here we have a thermometer. Let’s put the thermometer into the glass, we have to wait a bit for the temperature reading to adjust. For our listeners, it’s a digital thermometer with a metallic probe. You use similar thermometers to measure the inside temperature of a cake to check if it is finished baking.
