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.

Negative Afterimage

Reber Shukri Professor Vaughn Negative afterimage is a stimulus which elicits a positive image. In order to experience this, one can look at a bright source of light and then look away to a dark area. The way negative afterimage works is when the eye's photo-receptors which are the rods and cones adapt to over stimulation and lose sensitivity. The photo-receptors which are constantly exposed to the same stimulus will fatigue their supply of photo pigment, resulting a decrease in signal to the brain. The way negative afterimage connects to perception is because of bottom up processing where the stimulus influences what we perceive. https://www.youtube.com/watch?v=szy8iNCljlQ <Link to the video

Human Perception and it's Fascinating Facts

The human mind is capable of so many. different things that are turly incredible but most of the these incredbile things we take for granted. This article shows us the simple visual aspects and how our braing forms them within our mind. Throughout the article there are examples for different kinds of laws. These laws include Law of Proximity or Nearness, Law of Similarity, Law of Good Figure or Symmetry, Law of Closure, and Law of Continuity. All of these laws sound complicated and you amy assume that they are complex, however they aren't anywhere near that level. They are rather explnations for the reasoning behind why we perceive what we perceive. https://www.online-therapy.com/blog/human-perception-fascinating-facts/

Positivity

https://www.youtube.com/watch?v=kO1kgl0p-Hw&t=41s The video displays the power of the brain and the ways the brain can be tricked into doing things that would usually be out of someone's capabilities Two people were randomly chosen to shot free throws in basketball blind folded and then they took them of and shot them without. The first person missed all 10 blindfolded but was told that they were close or they went in when they didn't but when she took the blindfold off and shot them they were much closer and some actually went in, proving that the brain can be tricked by positivity. This relates to perception because if you tell yourself you can do something or someone is hyping you up into thinking you could do something you and your brain will preform better than with negative attitudes.
