The Rubber Hand Illusion: Is Seeing Believing?

The Rubber Hand Illusion: Is Seeing Believing?
This video demonstrates bottom up perception overriding top down knowledge. Initially, the participants had top down knowledge that the rubber hand was not their hand. Although the rubber hand looks similar to a real hand, it is clear the rubber hand is not a real hand. As the participants' real hand (that was hidden) and the rubber hand (not hidden) began being stimulated simultaneously, the participants' bottom up perception overrode their top down knowledge, and felt the rubber hand was their real hand. This was evident when the hammer hit the rubber hand and the participants reacted as if the hammer was hitting their real hand. This illusion demonstrates how our senses have the ability to deceive us, showing that seeing should not necessarily lead to believing.

Typoglycemia and Predictive Coding

He lists a multitude of studies that are relevant to the orders of the letters, the impact these jumbles have on reading speed, and more. The article makes a strong case that we read wo

The Brain's Fast and Slow Thinking

Our brain processes information through fast and slow thinking. During the first half of the semester we focused a lot on how we perceive information, and what is occurring in our brains as we are taking it all in. The video begins as it shows a basic contrast between fast and slow thinking. Something that would take a matter of seconds to draw a conclusion would be fast thinking, such as looking at a picture and analyzing the situation at hand. In contrast, a complex math problem would utilize slow thinking as our brains are working out the problem; it is not automatically known. The video emphasizes how our fast thinking is quick to make assumptions without looking deeply enough into a situation. It is up to us to let our conscious system (slow thinking) compensate and deeper analyze. This is seen with optical illusions. We need to use our conscious system to sort these illusions out for what they really are. Learning this importance of conscious thinking shows us that our first
